How is this list of alternatives built?

It is a rule over live records, not a hand-written list: every listing in Coinbase x402 Bazaar (Discovery API + MCP)'s own category that carries a Sato Score, ordered by the same evidence the rest of the site ranks on — Sato Score tier, whether an endpoint answered our probe, whether a deploy spec exists and was reproduced, a sustained observed record, and chain overlap with Coinbase x402 Bazaar (Discovery API + MCP). It is rebuilt from the records, so it changes when they do.

Rule · Every listing in Coinbase x402 Bazaar (Discovery API + MCP)’s own category (MCP) that carries a Sato Score, ordered by score tier, observed liveness, deploy-spec and reproduced-install evidence, and chain overlap with Coinbase x402 Bazaar (Discovery API + MCP).

This page ranks peers on how open, active and verifiable each one is — the same evidence Sato Hub publishes everywhere else.

A Sato Score is not an audit: none of these has been security-reviewed by Sato Hub, and a listing with no earned verification is self-reported.

“Differs on” is derived from the records — type, chains, openness and deployment — and states a difference, never a preference. ✓ marks an earned state named as what was checked; none of them is a safety claim.
