Dropspace API Skill

Multi-platform social media publishing with AI-generated content, per-post analytics, and persona-based writing styles.

Setup

Set your API key with least-privilege scopes (only grant what you need):

export DROPSPACE_API_KEY="ds_live_..."  # from dropspace.dev/settings/api

Recommended: Create a key with only read, write, generate scopes. Do not grant send or admin unless you explicitly need autonomous publishing or account management. You can always create a separate key with broader scopes later.

Base URL: https://api.dropspace.dev Auth header: -H "Authorization: Bearer $DROPSPACE_API_KEY"

Also available as MCP server: npx -y -p @jclvsh/dropspace dropspace-mcp Machine-readable docs: llms.txt | OpenAPI

API Key Scopes

Keys can be scoped to limit what they're allowed to do. Use least-privilege — only grant scopes your workflow requires.

Scope	What it allows
read	View launches, personas, connections, analytics, usage
write	Create and update launches and personas
generate	AI content generation (text from descriptions)
send	Publish launches to connected social accounts and deliver webhooks
admin	Manage API keys and webhooks

Legacy publish and delete scopes still authenticate for grandfathered keys (publish → send, delete → write), but new keys should use the current scope names.

Use Case	Recommended Scopes
AI agents / MCP (draft + review)	read, write, generate
AI agents / MCP (auto-publish)	read, write, generate, send
CI/CD publishing	read, write, send
Monitoring / dashboards	read
Full access (admin tools)	all scopes

Missing scope returns 403 with AUTH_002.

Audit Logging

Destructive/sensitive API operations are automatically logged: delete launch/persona, publish, create/revoke key, create/delete/rotate webhook.

Supported Platforms

twitter, linkedin, reddit, instagram, tiktok, facebook, youtube, producthunt, hackernews, substack

Per-Platform Character Limits

Twitter 280/tweet (25,000 for X Premium) × 6 tweets (use thread array or content string), LinkedIn 3,000, Instagram 2,200, Reddit 3,000, Facebook 3,000, TikTok 4,000, YouTube 5,000 description / 100 title, Product Hunt 500, Hacker News 2,000, Substack 3,000

Core Workflow: Create & Publish

1. Check connected platforms

# User's OAuth connections
curl -s https://api.dropspace.dev/connections \
  -H "Authorization: Bearer $DROPSPACE_API_KEY"

# Official Dropspace accounts available for posting
curl -s https://api.dropspace.dev/dropspace/status \
  -H "Authorization: Bearer $DROPSPACE_API_KEY"

Connections: OAuth-connected accounts with platform, username, account_type, is_active, expires_at. Managed via dashboard. Dropspace status: Shows which official Dropspace accounts (facebook, linkedin, twitter, reddit, instagram, tiktok, youtube) are connected and available for the dropspace_platforms field.

2. Create a launch (AI generates platform-specific content)

curl -s -X POST https://api.dropspace.dev/launches \
  -H "Authorization: Bearer $DROPSPACE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "title": "launch title",
    "product_description": "what to post about (1-2000 chars)",
    "platforms": ["twitter", "linkedin", "reddit"],
    "product_url": "https://optional-url.com",
    "persona_id": "optional-uuid",
    "scheduled_date": "optional ISO 8601 (≥15 min future)",
    "publish": "optional boolean — immediately publish after creation (returns 202, mutually exclusive with scheduled_date, requires write+send scopes)",
    "wait": "optional boolean — wait for publishing to complete and return post URLs inline (requires publish: true, returns 200 with posting_status)",
    "dropspace_platforms": ["twitter"],
    "user_platform_accounts": {"twitter": "account-id"},
    "media": [
      {"source": "url", "url": "https://example.com/image.png"},
      {"source": "base64", "data": "iVBOR...", "filename": "slide.png", "mime_type": "image/png"}
    ],
    "media_attach_platforms": ["twitter", "linkedin"],
    "media_mode": "images|video",
    "custom_content": "single text for all platforms (validated against lowest char limit)",
    "custom_content_reddit_title": "reddit title when using custom_content (max 300 chars)",
    "platform_contents": {
      "twitter": {"thread": ["tweet 1", "tweet 2", "tweet 3"]},
      "reddit": {"title": "...", "content": "..."},
      "linkedin": {"content": "custom post"},
      "tiktok": {
        "content": "caption text",
        "tiktok_settings": {
          "privacy_level": "PUBLIC_TO_EVERYONE",
          "auto_add_music": true,
          "allow_comments": true,
          "allow_duet": true,
          "allow_stitch": true
        }
      }
    }
  }'

Content auto-generated via Claude from description + scraped URL + persona.

Content options (mutually exclusive):

• Omit both → full AI generation for all platforms
• platform_contents → per-platform custom content. Platforms without content get AI-generated. Reddit requires title. Product Hunt/HN support optional title (max 60/80 chars). Twitter supports thread (string[], each ≤280 chars or ≤25,000 for X Premium, max 6 tweets) instead of content — mutually exclusive with content.
• custom_content → string distributed to all platforms (validated against most restrictive char limit), or string[] to create a Twitter thread (each ≤280 chars or ≤25,000 for X Premium, max 6) that joins with double newlines for other platforms. Array form requires Twitter in platforms. Use custom_content_reddit_title if Reddit is included.

user_platform_accounts key format:

• Simple keys: "twitter", "reddit", "instagram", "tiktok"
• LinkedIn personal: "linkedin:personal" → personal profile
• LinkedIn org: "linkedin:organization:<org_id>" → company page
• Facebook page: "facebook:page:<page_id>"
• Multiple keys allowed (e.g. post to personal + org simultaneously)

TikTok settings (platform_contents.tiktok.tiktok_settings):

• privacy_level (REQUIRED before publishing): "PUBLIC_TO_EVERYONE", "FOLLOWER_OF_CREATOR", "MUTUAL_FOLLOW_FRIENDS", or "SELF_ONLY"
• Optional booleans: allow_comments, allow_duet, allow_stitch, is_commercial, is_your_brand, is_branded_content, auto_add_music
• Branded content (is_branded_content: true) cannot use SELF_ONLY privacy
• Can be set at creation or updated via PATCH (deep-merged)

Inline media upload (media field): Upload images/videos inline via URL or base64 — server handles storage upload and populates media_assets in the response. Max 10 items (9 images + 1 video). Images: jpeg/png/webp/gif (5MB). Videos: mp4/mov (512MB via URL, 4MB via base64). media_attach_platforms and media_mode auto-inferred if not set. Mutually exclusive with media_assets.

Pre-uploaded media (media_assets field): For files already in storage — requires id, url, type, filename, size, mime_type. Mutually exclusive with media.

Media limits: Instagram/Facebook 10, Reddit 20, TikTok 35.

Inline publish (publish + wait fields):

• publish: true → immediately publish after creation (returns 202). Mutually exclusive with scheduled_date. Requires both write and send scopes.
• wait: true (requires publish: true) → wait for publishing to complete synchronously and return 200 with posting_status containing per-platform results and post URLs. Typical wait: 10-30s for text platforms, up to 60s+ with Instagram/TikTok.
• If publish validation fails after creation, returns 201 with publish_error: { code, message } — retry via POST /launches/:id/publish.

Publish validation (LAUNCH_007): When publishing fails validation, the response includes a details array listing all blocking issues. Checks include: char limits (all platforms), Reddit title ≤300 chars, Reddit video needs video+thumbnail, Reddit images need images, Instagram reel needs video, Instagram carousel needs ≥2 images, TikTok requires tiktok_settings.privacy_level, TikTok video needs video, TikTok photo needs images. Instagram requires media. TikTok requires video or photos. media_mode: "images" or "video" (auto-inferred when using media).

Upload errors: UPLOAD_001 (unsupported type), UPLOAD_002 (too large), UPLOAD_003 (storage upload failed).

3. Review & edit content

# Edit specific platform content:
curl -s -X PATCH https://api.dropspace.dev/launches/LAUNCH_ID \
  -H "Authorization: Bearer $DROPSPACE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"platform_contents": {"twitter": {"thread": ["tweet 1", "tweet 2", "tweet 3"]}}}'

# Or regenerate for specific platforms:
curl -s -X POST https://api.dropspace.dev/launches/LAUNCH_ID/generate-content \
  -H "Authorization: Bearer $DROPSPACE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"platforms": ["twitter"]}'

4. Publish

curl -s -X POST https://api.dropspace.dev/launches/LAUNCH_ID/publish \
  -H "Authorization: Bearer $DROPSPACE_API_KEY"

Returns 202. Async — poll /status or use webhooks (launch.completed, launch.failed, launch.partial).

5. Check posting status

curl -s https://api.dropspace.dev/launches/LAUNCH_ID/status \
  -H "Authorization: Bearer $DROPSPACE_API_KEY"

Returns per-platform posting logs with status, post_url, post_id, error_message, error_code, attempt_count, posted_at.

6. Get per-post analytics with engagement metrics

curl -s https://api.dropspace.dev/launches/LAUNCH_ID/analytics \
  -H "Authorization: Bearer $DROPSPACE_API_KEY"

Returns per-platform metrics (live refresh — fetches from platform APIs when stale >5 min):

• Twitter: likes, retweets, replies, quotes, bookmarks, impressions, urlClicks, profileClicks
• LinkedIn: impressions, uniqueImpressions, likes, comments, shares, clicks, engagement
• Facebook: reactions, comments, shares
• Instagram: views, engagement, saved, likes, comments, shares
• Reddit: score, upvotes, upvoteRatio, comments
• TikTok: views, likes, comments, shares

Response includes fetched_at, next_refresh_at (fetched_at + 5 min), and per-platform cache_status (fresh | refreshed | stale). Calling the endpoint triggers a refresh automatically when data is stale.

Batch Analytics

# Fetch analytics for up to 100 launches in one request
curl -s "https://api.dropspace.dev/launches/analytics?ids=uuid1,uuid2,uuid3" \
  -H "Authorization: Bearer $DROPSPACE_API_KEY"

Returns { data: [...], errors: [...] } with partial success support. Each item includes launch_id, platforms (with per-platform metrics + deletion info), and status. No fetched_at/next_refresh_at (those are single-launch only). Uses cached metrics — does not trigger live refresh from platforms.

Post Deletion Detection

Analytics responses include deletion detection fields per platform:

• is_deleted (boolean) — true if the post was detected as deleted/removed
• deleted_detected_at (ISO 8601) — when deletion was first detected
• deletion_reason — one of: not_found (404), gone (410), creator_deleted, moderation_removed, account_deleted, spam_filtered

Platform-specific detection:

• LinkedIn: Detects REMOVED_BY_LINKEDIN_TAKEDOWN
• Reddit: Checks removed_by_category
• Twitter: Catches authorization errors as possible account deletion
• TikTok/Instagram/Facebook: Detects 404/410 responses

Deletion is detected during the analytics cron refresh cycle (runs every 5 minutes for recently active posts).

First-Touch Attribution (Built-in)

Dropspace has built-in signup attribution via Next.js middleware → httpOnly cookie → profiles table.

How it works:

1. First page visit → middleware captures referrer + UTM params into ds_attr cookie (30-day expiry)
2. On signup → auth callback writes to profiles.signup_referrer, signup_utm_source, signup_utm_medium, signup_utm_campaign

Add UTM params to links:

https://www.dropspace.dev?utm_source=tiktok&utm_medium=social&utm_campaign=slideshow_feb

Query attribution data via Supabase:

SELECT signup_referrer, signup_utm_source, signup_utm_medium, signup_utm_campaign, created_at
FROM profiles
WHERE created_at >= now() - interval '7 days'
AND signup_utm_source IS NOT NULL;

Launch Management

Method	Endpoint	Description
GET	/launches	List all (paginated: page, page_size 1-100)
POST	/launches	Create with AI-generated content
GET	/launches/:id	Get single with posting_status
PATCH	/launches/:id	Update draft/scheduled/cancelled (name, content, schedule, status, media, dropspace_platforms, user_platform_accounts)
DELETE	/launches/:id	Delete (not running)
POST	/launches/:id/publish	Publish (async, 202)
POST	/launches/:id/retry	Retry failed platforms only
POST	/launches/:id/retry-content	Retry content generation for failed platforms (optional platforms filter)
POST	/launches/:id/generate-content	Regenerate AI content (optional platforms)
GET	/launches/:id/status	Detailed posting logs
GET	/launches/:id/analytics	Per-post engagement metrics (live refresh, 5-min cache)
DELETE	/launches/:id/posts/:logId	Delete a single published post from platform (logId from /status)
DELETE	/launches/:id/posts	Delete all published posts for a launch

Launch Status Lifecycle

Statuses in lifecycle order: draft → manual → trigger → scheduled → running → completed / partial / failed / cancelled

Status	Cron auto-publishes?	Dashboard action buttons?	Can publish via API?	Use case
draft	❌	❌	✅	Initial creation, not ready
manual	❌	✅	✅	Ready, waiting for manual publish
trigger	❌	✅	✅	Ready, waiting for explicit trigger
scheduled	✅ (when scheduled_date ≤ now)	✅	✅	Will auto-publish at scheduled time
running	—	—	—	Currently publishing
completed	—	—	—	All platforms succeeded
partial	—	—	✅ (retry)	Some platforms failed
failed	—	—	✅ (retry)	All platforms failed
cancelled	—	—	✅ (retry)	Manually cancelled

Key rules:

• The publish cron only picks up scheduled launches with scheduled_date ≤ now. All other statuses require manual action.
• Status is auto-derived on PATCH for editable launches (draft/manual/trigger/scheduled). The server overrides your requested status based on configuration:
  • Has user_platform_accounts or dropspace_platforms + scheduled_date → scheduled
  • Has user_platform_accounts or dropspace_platforms + no scheduled_date → trigger
  • Has content + no posting accounts → manual
  • This means you cannot force manual on a launch that has posting accounts. It will auto-transition to trigger.
• To unschedule without losing settings: PATCH with {"scheduled_date": null}. The server will auto-set status to trigger (since posting accounts exist). Do NOT set to draft (loses dashboard action buttons) or DELETE (soft-deletes, hard to recover).
• To pause a scheduled launch: PATCH {"scheduled_date": null}. Status becomes trigger automatically.
• POST /launches/:id/publish triggers immediate publishing regardless of scheduled_date. Never call this on scheduled launches unless you want them published now.
• manual = no posting accounts configured (publish manually). trigger = has posting accounts but no schedule (publish on demand).

PATCH fields: name (1-200 chars), scheduled_date (ISO 8601 | null to unschedule), status, platforms, product_description (max 10,000 chars), product_url (empty string to clear), persona_id (null to clear), platform_contents (deep-merged per platform — existing platforms preserved, within a platform included fields replace old values), user_platform_accounts, dropspace_platforms, media/media_assets (replaces entirely), media_attach_platforms, media_mode. All optional but ≥1 required. Running launch can only be cancelled. TikTok tiktok_settings is deep-merged (can update individual fields without overwriting others).

Note: Media generation (AI image/video via fal.ai) is not available through the public API. Media upload (attaching existing images/videos) is supported.

Deleting Published Posts

• Requires write scope on API key (legacy delete scope still works for grandfathered keys)
• Works on: Twitter, Facebook, LinkedIn, Reddit
• Does NOT work on: Instagram, TikTok (returns DELETE_NOT_SUPPORTED — manual deletion required)
• logId is the posting_log UUID from the /status endpoint
• If post was already deleted on platform (404), treated as successful deletion
• On success, posting log status updated to deleted
• Use Dropspace API: DELETE /launches/:id/posts/:logId or DELETE /launches/:id/posts

Agent Payments (x402 + MPP)

Autonomous agents can use the API without accounts or subscriptions via two payment protocols:

x402 (crypto): USDC on Base via X-PAYMENT header (base64-encoded proof) MPP (Stripe): Card charge via Authorization: Payment <base64url> header

• Only supported on launch endpoints (create, list, get, update, delete, publish, status)
• 5 free launches/month using official Dropspace accounts
• Beyond free tier: $0.50 per launch creation (paid at creation, publishing is always free)
• Agent users can only post to official Dropspace accounts (not connected user accounts)
• Rate limit: 30 req/min per agent identity (wallet address for x402, payer credential for MPP)
• On 402 response, body contains both x402 and mpp challenge objects

Rate Limits

Limit	Value
General API	60 req/min per API key
Content generation	30 req/min per user

On 429: check Retry-After header (seconds). Rate limit headers: X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Reset (Unix timestamp in milliseconds, not seconds).
