  Live unauthenticated GET https://api.execution.market/api/v1/health on 2026-09-19 returned x-ratelimit-remaining: 32,
  x-ratelimit-tier: free, x-ratelimit-class: public, x-request-id, x-response-time. No x-ratelimit-limit or
  x-ratelimit-reset header was present on that 200; skill.md tells clients to honour X-RateLimit-Reset on a 429, so
  the reset header is expected on exhaustion. No 429 was provoked by this pipeline.
confidence: medium
confidence_note: >-
  Two provider pages give different numbers on different axes: skill.md (v14.3.0, 2026-09-13) states per-operation
  hourly limits; the docs REST page states per-minute limits by auth tier and still lists an "API Key" tier that
  auth.md says is disabled in production. Both are recorded; the skill file is the more recent and is what agents are
  told to refresh before every task.
