x402 Entity-ID Resolver
GET entityresolver.xyz/resolve
Why an agent can trust this route.
Sonar evidence is advisory. Paid delivery is shown as verified only when paid probes are available; otherwise route estimates use the unpaid handshake as a clearly labeled proxy.
Observed outcomes
Name in, official IDs out. Give it a company or crypto name or ticker ("Apple", "ETH", "Stripe") and get the verified IDs that identify it everywhere: SEC CIK + ticker, GLEIF LEI, Wikidata QID, CoinGecko slug. Every ID is pulled live from the entity's own official registry and tagged with the sources that agreed — so you can check it yourself, not trust an LLM's guess. Ranked by confidence.
