Find better alternatives to an x402 endpoint.

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. The price fields stay machine-readable: amountUsd is always the raw advertised amount, and the separate boolean priceCeiling is true when the endpoint uses the x402 'upto' scheme, i.e. amountUsd is an authorization ceiling and the real charge is typically lower. Same-host siblings and 'avoid'-flagged endpoints are excluded. Returns an empty list (still a valid answer) when nothing beats the subject.
