Relay · Rate Limits

Val Run Rate Limits

Relay publishes no rate-limit documentation (its documentation host is a paused surge.sh page, HTTP 403). The endpoint does return a runtime rate-limit signal on every response, but it is set by the hosting platform's edge (Val Town, fronted by Cloudflare and Render), not by Relay: the identical x-ratelimit-* triple appears on a nonexistent *.web.val.run host (HTTP 500) and on every response from Relay's val. Recorded because it is the signal an agent calling Relay actually receives; attributed to the platform because that is who sets it.

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

It captures 1 rate-limit definition.

Limit state is signalled in the observed, checked_for, and not_observed response headers.

Tagged areas include Company, AI Agents, A2A, Human-in-the-Loop, and Physical Tasks.
