How we measure: before is a direct call to AgentDataAPI from Cloudflare's edge (successful probes only); after is what an API-key caller gets at the edge: the read of our cached copy at the same edge location plus the gateway's own time per request. A cache miss adds the provider's time. Both leave out the agent-to-edge leg, which is the same either way. 24-hour p50 and p95, updated hourly. Last updated 2026-11-11 07:07 UTC.
