x402 reliability index

Published free by Aegis by Boris Inc · generated 2026-08-20T17:31:08Z · JSON · no payment, no key, no account.

65% of indexed x402 endpoints are not healthy right now.

Most of the machine economy's advertised endpoints do not answer. An agent that pays before it checks is paying into that failure rate. Aegis exists to verify delivery before the payment, not after.

The x402 universe — measured by 402index.io, not by us

95,418 endpoints across 3,798 services, from 402index.io's free public API (/api/v1/health). Retrieved 2026-08-20T17:31:03Z; cached at least 15 minutes. Their measurement, reproduced with credit — Aegis did not probe these endpoints.

What Aegis measures itself

Aegis registry (aegis.borisinc.com) — our own probes. These numbers are ours.

4,355 services scored, 4,352 registered
5,287,638 probes recorded
4,679 delivery spot-checks, of which 318 were real on-chain purchases
tiers: flagged: 325 · provisional: 815 · trusted: 131 · unverified: 5 · verified: 3,079

A trust score here is backed by a real purchase: Aegis buys from sellers on a schedule and records whether they actually delivered. Method: /spec. Aegis rates its own endpoints too and marks them self=1.

Honest framing

This index is free and unauthenticated. There is no x402 challenge on it and there never will be.
Aegis makes no revenue claim and no traction claim on this page. These are measurements, not business metrics.
Upstream universe counts are cached for at least 15 minutes out of respect for a free third-party API.
The two datasets above are shown side by side and are never merged. 402index.io counts the universe; Aegis counts what Aegis has verified.
