PAYMENT-REQUIRED header, so services that were live and serving valid v2 challenges were recorded here as dead or broken.
Fixed on 2026-07-30: every tracked endpoint was re-probed, live endpoints went from 1452 to ~3480 and the dead share from 74% to ~38%.
Do not cite the liveness numbers on this page. See the current report and methodology. The scam/anomaly findings are unaffected.
Snapshot of the x402 agent-payment ecosystem as of 2026-07-07 · by PulseFeed · see the live report →
of the services 402index lists as "healthy" actually return a valid x402 challenge under PulseFeed's independent probe. We caught 1064 of 2039 listed-healthy endpoints that did not return a valid x402 challenge to our probe. (Superseded — see the correction above: this count includes live x402 v2 services our old prober could not read.) Agents shouldn't trust a listing blindly.
| Date | Services | Endpoints | Catalog acc. | Dead |

Methodology: PulseFeed continuously crawls x402 catalogs (CDP Bazaar + 402index), independently probes every endpoint for a valid x402 challenge, verifies each payTo on-chain, and tracks payTo/price history over time. This report is generated automatically from that data and updates daily.
