Find better alternatives to an x402 endpoint. Given a resource URL, returns the top semantically-similar endpoints (matched on advertised purpose via description embeddings) that currently OUT-SCORE it on our deterministic trust score — so an agent about to pay a mediocre endpoint can discover a more reliable, better-settled one serving the same function. Each result carries its trust score, grade, cosine similarity, advertised price and free endpoint-page URL. Same-host siblings and 'avoid'-flagged endpoints are excluded. Returns an empty list (still a valid answer) when nothing beats the subject.
# 1. Ask the endpoint what it costs (no payment, no wallet needed): curl -i -X POST 'https://x402.fuchss.app/v1/similar' # -> HTTP/1.1 402 Payment Required # the response carries the price, asset and pay-to address. # 2. Pay and retry with any x402 client: npx x402-fetch -X POST 'https://x402.fuchss.app/v1/similar'
Endpoint: https://x402.fuchss.app/v1/similar. Operated by x402.fuchss.app, not by Animica. Price and availability were correct at the last probe on 2026-09-02 and are set by the operator, who may change them.
