# ERC-8004 Registry Entry Verifier

`POST /v1/tools/verify_erc8004_registry_entry`

## Request

- Base URL: `https://ainumbers.co`
- URL: `https://ainumbers.co/v1/tools/verify_erc8004_registry_entry`
- Auth: none declared

Checks whether a caller-supplied claimed ERC-8004 agent registry entry (Identity, Reputation, or Validation registry) and a caller-supplied on-chain record, independently read by the caller from the registry contract, agree field-by-field, and separately whether any address-shaped field in the on-chain record is EIP-55 checksum-valid. Zero network calls; this tool never queries a registry contract itself, so it makes no claim about the current on-chain state, only that the two supplied records are consistent with each other at the time supplied. Generic schema only, no per-registry-type adapter code -- the caller supplies both records as arbitrary key-value pairs. agent_id is compared as an opaque literal string throughout: never parsed as a number, never resolved against an Agent Card or A2A endpoint, never cached, and never cross-referenced against another registry. Two independently reported findings, never fused into one boolean.
