Limitless API rate limits

As of July 31, 2026, Limitless warm book latency is 317 ms at the median (p50, 24h window), with 392 ms at p90 and 1.28 s at p99. Limitless ranks #2 of 4 chains measured on this benchmark.

Limitless documents no rate limits, so it gets the most conservative ramp in the cohort (10/20/40 per 10s, auto abort). Measured quirk: error responses are CDN cached for four hours, so one expired market keeps answering with the same 400 long after resolution. The harness treats those as probe_invalid and re pins rather than counting them against the venue. Warm book p50: 317 ms.
