X402 List Api Rate Limits

Two independent throttles, both keyed on client IP and both signalled in response headers rather than only in prose: a 200 req/min sliding-window rate limit that returns 429 with Retry-After, and a 2,000 GET/day metering quota that returns 402 and can be paid through rather than waited out. The soft advisory band above 100 req/min is unusual and worth noting — requests still succeed, the API just tells the client it is approaching the ceiling.

X402 List Api Rate Limits is the machine-readable rate-limit profile for x402 List API on the APIs.io network, in the API Commons Rate Limits shape.

It captures 2 rate-limit definitions, measuring requests_per_minute and get_requests_per_day.

Limit state is signalled in the rateLimit, rateLimitRemaining, rateLimitReset, and rateLimitThrottled response headers, and an exhausted limit returns HTTP 429.

The profile also includes response codes documented for throttled and metered.

Tagged areas include x402, Cryptocurrency, 402, Agentic Payments, and API Directory.
