Traces

Historical callTracer trace tree for a whole block

Reconstructed call tree per transaction in a block using callTracer, wrapped in the standard response envelope. Returns the whole block, unpaginated (next_cursor is never present). A permanent coverage gap returns 422, never an empty array; a recent block with transactions but no trace data yet returns 503 instead -- once it is further behind the indexed head than the chain's trace window, it is 422 too (see "Errors" above).

Path parameters

chainstring required

Chain identifier: the chain value of an entry in GET /chains (for example robinhood_mainnet), which lists every value this API accepts, i.e. the exact lowercase form of that entry's chain_slug. Matching is exact and case-sensitive; other spellings, aliases and numeric chain IDs are not accepted and return 404 not_found (unknown or not-public chain). What the chain serves differs per chain: see that entry's features and coverage.

numberinteger required

Non-negative block height.

Response

One call tree per transaction in the block, in tx_index order ([] for a real, finalized block that has zero transactions).
