AgentCash — Paid API Access

Call any x402 or MPP-protected API with automatic wallet authentication and payment. No API keys or subscriptions required.

Check Balance

agentcash.get_balance()

Returns total USDC balance across supported networks. Use this before paid calls to confirm funds are available.

Redeem Invite Code

agentcash.redeem_invite(code="YOUR_CODE")

One-time use per code. Credits added instantly. Run agentcash.get_balance() after to verify.

Deposit USDC

1. Call agentcash.list_accounts() to get per-network wallet addresses and deposit links
2. Send USDC on Base network (eip155:8453) or Solana (solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp) to the matching address
3. Or open the returned deposit link for the selected network

Important: Only Base or Solana network USDC. Other networks or tokens will be lost.

Calling Paid APIs

1. Pick an origin — or search

Check the Available Services table below first. If any origin clearly covers the task, skip search entirely and jump to step 2 (discover). Examples:

Task	Origin (skip search)
Look up a person or company	stableenrich.dev
Generate an image or video	stablestudio.dev
Get Instagram/TikTok data	stablesocial.dev
Send an email	stableemail.dev
Upload a file	stableupload.dev

Only use search when none of the listed origins fit:

agentcash.search(query="send physical mail")

Returns matching origins with endpoints and pricing (the top match often includes schema so you can call fetch immediately).

2. Discover endpoints

agentcash.discover_api_endpoints(url="https://stableenrich.dev")

Returns all endpoints, pricing, and usage instructions. Read the instructions field — it has critical endpoint-specific guidance.

3. Check schema (optional)

agentcash.check_endpoint_schema(url="https://stableenrich.dev/api/fullenrich/people-search")

Returns full request/response JSON schemas and pricing for a specific endpoint.

4. Make a paid request

agentcash.fetch(
  url="https://stableenrich.dev/api/fullenrich/people-search",
  method="POST",
  body={
    "current_company_domains": [{"value": "stripe.com"}],
    "current_position_seniority_level": [{"value": "VP"}]
  }
)

Payment is automatic: sends request, gets 402 challenge, signs USDC payment, retries with credential, returns result. Payments settle only on success (2xx) — failed requests cost nothing. agentcash.fetch also handles SIWX-authenticated endpoints automatically when the route supports that flow.

Tips

• Skip search when a listed origin fits the task. Go straight to discover_api_endpoints. Only use search when no origin in the Available Services table matches.
• Always discover before calling arbitrary paths — the instructions field has critical endpoint-specific patterns and required parameters.
• Payments settle only on success (2xx) — failed requests cost nothing.
• Use check_endpoint_schema when unsure about request/response format.
• Independent agentcash.fetch calls can run in parallel for better throughput.
• Network: Base (eip155:8453) or Solana (solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp), Currency: USDC.

Troubleshooting

Issue	Solution
"MCP tool not found"	Reinstall MCP, restart IDE
"Insufficient balance"	Run agentcash.get_balance(), then agentcash.list_accounts() or redeem an invite code
"Payment failed"	Transient error — retry the request
"Invalid invite code"	Code already used or doesn't exist
Balance not updating	Wait for Base or Solana network confirmation (~2 sec)
