Get the verified metadata of a contract: name, ABI methods and proxy/implementation split, with optional calldata decoding.

Verified metadata does not certify that a contract is secure. Coverage is limited: on 2026-11-06 several well-known Ethereum contracts answered 422 unsupported. When you already have the ABI, calldata decode is the dependable path.

Released on Ethereum. Any other chain value answers 422 with state unsupported. More chains are coming; see the changelog.

Every answer is an envelope with state, meta, optional data and optional error. Read state first: ok, empty, partial, stale, unsupported or unavailable (see response states). meta.cached tells you whether the answer came from cache.

Parameters

addressstringrequired

Address to look up: 0x + 40 hex characters, any letter case.

callDatastringoptional

Optional calldata (0x…) to decode against the ABI.

chainstringrequired

Chain id, see Network above (eth, and for labels also solana and avalanche). Aliases: ethereum → eth, sol → solana, avax → avalanche.

freshbooleanoptional

Optional. true skips the cache and asks for a new lookup (GET routes: ?fresh=1).

Response

Illustrative response; values are examples, not a recorded observation.

Errors

HTTP	`error.code`	When
400	`invalid_request`	Malformed address, unknown field, `null` value or invalid JSON.
401	`unauthorized`	Missing or invalid API key.
403	`scope_missing` / `tier_insufficient`	The key lacks `intelligence:read`, or the plan is below Business.
405	`method_not_allowed`	Wrong HTTP method; the `Allow` header names `POST`.
422	`unsupported`	The chain (or the contract) is not supported by this method.
429	`rate_limited`	Over the `intelligence` per-second limit; wait `Retry-After` seconds.
503	`unavailable`	The lookup could not be completed right now; retry later.
504	`timeout`	The lookup took too long; retry, or retry later with the same input.
