generated: '2026-08-12' method: probed source: >- Response headers observed on live unauthenticated requests to https://mcp.valid.co/health, https://mcp.valid.co/api/mcp/ and https://api.valid.co/ on 2026-08-12, plus a search of valid.co for any published limits. limit_count: 0 limits: [] headers: [] status_on_exhaustion: null notes: >- Valid documents no rate limits anywhere on its public surface — there is no developer portal, no API reference and no mention of limits in the terms of service. Nor are limits signalled at runtime: no RateLimit-*, X-RateLimit-*, or Retry-After header appeared on any response from mcp.valid.co (repeated requests to /health), from the MCP endpoint's 401, or from the Kong gateway at api.valid.co. An agent calling this surface has no way to learn its budget in advance and no runtime signal to back off on — it would have to infer throttling from failures. Recording the honest zero: nothing published, nothing signalled. This says nothing about whether limits are enforced behind the auth gate, only that they are not observable.
