API Scoreboard
Independent, probe-based quality scores for paid agent APIs (L402 & x402), grouped by data type: crypto, stocks, weather, traffic and more. Every verified L402 API here can also be called through BitTuitive with one payment (router).
1256L402 endpoints discovered
2950x402 endpoints discovered
417endpoints scored
2026-11-15 17:41:07 UTClast probe cycle
Scores (0-100) come only from Bittuitive's own automated, unpaid probes over a rolling 7 days: availability 35, valid payment challenge 25, latency 15, price consistency 15, listing completeness 10. Nobody can pay for a better score, and Bittuitive's own endpoints are scored by the same rules. Categories are assigned automatically from each listing's name, description, directory category and URL.
