Before and after: 3 of 6 endpoints are answered from our edge cache instead of a round trip to AgentDataAPI.
Why use RealtimeAPI
Cached answers from Cloudflare's edge in 300+ cities, measured every 5 minutes.The same data AgentDataAPI serves, refreshed on its schedule: freshness shown per endpoint, and every answer says how old the copy is (X-RTAPI-Data-Age).One API key for every feed.Pay per call in USDC (x402), buy a 1-hour, 1-day, 7-day or 30-day pass, or prepay USDC credits.MCP tools for agents: Claude, Cursor or any MCP client can call this feed directly.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 07:00 UTC.
