# 404 Mentions API — product mention tracking
Find where a product or topic is being discussed on Reddit and Hacker News.
## Endpoint
GET `https://mentions-api-404-production.up.railway.app/v1/mentions`
Header: `Authorization: Bearer <API_KEY>`
| Param | Values | Notes |
| --- | --- | --- |
| `product` | any name, e.g. `linear.app` | ≥2 chars, required |
| `days` | 1–365 | lookback window, default 7 |
| `sample` | `true` | sandbox mode — free, no credits billed |
## Quick test (no key needed for a feel of the shape — get a key at https://404kidwiz.github.io/mentions-api/)
```bash
curl -H "Authorization: Bearer $MENTIONS_KEY" \
"https://mentions-api-404-production.up.railway.app/v1/mentions?product=linear.app&days=30"
```
Response: recent mentions (`source`, `title`, `url`, `score`, `created`), plus `credits_remaining`.
## Workflow
1. Run with `sample=true` first to preview results for free.
2. Remove `sample` for the full live pull — bills 1 credit per call.
3. Daily cap enforced server-side; errors are never billed.
## Getting a key / topping up
- Keys and credit packs: **https://404kidwiz.github.io/mentions-api/** — $10 = 100 credits via Stripe.
- Top-up link pattern: append `?client_reference_id=<your_api_key>` to the buy link so credits land on your key automatically.
## Tips
- Query the bare domain (`linear.app`) rather than the brand word — matches more Reddit/HN titles.
- Rate limit: 429 means slow down; 401 means bad key.
