Coin Metrics Rate Limits

Published Coin Metrics API v4 rate limits. Four rate-limit plans (Community, Trial, Default/PRO, Download/PRO) with sliding-window request limits, a cap of 10 parallel REST requests, and 200 parallel WebSocket connections for paid keys. 429 on violation with X-RateLimit-* headers per draft-polli-ratelimit-headers-03 plus an X-RateLimit-Plan header (default | trial | download | community).

Coin Metrics Rate Limits is the machine-readable rate-limit profile for Coin Metrics on the APIs.io network, in the API Commons Rate Limits shape.

It captures 6 rate-limit definitions, measuring requests_per_window, concurrent_requests, and concurrent_connections.

Limit state is signalled in the limit, remaining, reset, and plan response headers, and an exhausted limit returns HTTP 429.

The profile also includes response codes documented for throttled.

Tagged areas include Rate Limiting, Crypto, and Market Data.
