The latest block number seen by the intelligence layer, as an exact decimal string.

Use it to judge how fresh intelligence data is. It is not the canonical chain head: read that from Ethereum JSON-RPC (eth_blockNumber).

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

chainstringrequired

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

fresh0 or 1optional

Query parameter. 1 skips the cache and asks for a new lookup.

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 `GET`.
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.
