pulse.chainverdict.xyz
API uptime and reliability monitoring for any x402 endpoint: a live quality verdict covering availability, uptime, latency percentiles, 402-offer conformance, price-drift and payTo-stability flags. Deterministic and re-verifiable. (5 paid endpoints on pulse.chainverdict.xyz.)
Call it with x402
A paid HTTP API. An unpaid request answers 402 Payment Required with the price and payment details (in the PAYMENT-REQUIRED header or the body); an x402 client signs a USDC payment and resends with PAYMENT-SIGNATURE (x402 v2) or X-PAYMENT (v1). No account or API key. Prices and limits are set by its operator.
See the price (free, unpaid)
curl -i https://pulse.chainverdict.xyz/v1/verdict
Some endpoints expect POST with a JSON body; the 402 and its docs say which.
New to paying per call? x402 for agents explains the 402 → pay → retry loop.
Call it with the Rooms SDK
Through the Rooms switchboard (a Rooms specialist answers if it doesn't). SDK docs
