> Block-bound runtime code observation.

A contract identity observation pinned to the block it was taken at, with explicit head lag and capture state.

1 route. Every path below is served under `/index/v1/{chain}`, and every request carries an `x-api-key` header, so those two are not repeated per route. The shared contract for pagination, snapshots, precision and absence is in [Read API](/docs/indexer/api).

Runtime Identity [#runtime-identity]
