Fallback Resolve

by agent.halowerk.com in Search & web

x402 APIPassing, checked 3 h ago

Searches the public x402 discovery catalogue for services able to replace a broken dependency. Give the failed URL and, better still, a short description of what it did and the fields you need back; matches are scored on overlap between your task words and the candidate name, description and path, then ordered by score and price. Every hit carries the reason it matched, its price in USDC, its network and when the catalogue last saw it.
