The curated directory for the x402 ecosystem
Every service on the Gold-402 list is one we put there on purpose — with the independent health, uptime, and trust grades from across the ecosystem gathered in one place. Don't let your agents trade in the dark.
What this is
24K Labs runs the Gold-402 Directory — a curated map of the x402 ecosystem. The x402 protocol lets an AI agent pay for a service in USDC and get its result with no account and no API key. The catch: the endpoints are scattered, and plenty are dead, mislabeled, or vaporware. This directory is the layer that sorts the real from the noise.
Being on the list is the whole point. Each entry gets its own page — our note on the service, the endpoint, and any independent trust grades we can pull in from raters across the ecosystem. Nothing here is pay-to-list.
How the directory works
A list you can trust, and the grades to back it up.
Curated, not scraped
A service earns its spot through a submission, not an algorithm. If it isn't real, it doesn't go on the list.
Grades from the ecosystem
Where independent raters (like fuchss) publish a live grade for an endpoint, we surface it right on the listing.
Built for agents
The Verify API returns our verdict plus aggregated rater grades for any resource in one call — x402-gated at $0.001, no key.
The human layer of the x402 economy
x402 is backed by the Linux Foundation with 50+ member organizations including Coinbase, Cloudflare, Stripe, Visa, and AWS. The protocol moves the money; the directory tells you which endpoints are worth paying.
