}Get many Plutus datums by hash in one call
Resolve up to 100 datums in one call. Every requested hash is a key of the response’s data object, in request order; a hash with no datum on chain maps to null rather than being dropped, so the response can be read against the request without re-deriving it. Values are the same hex CBOR the single-datum endpoint returns under ‘cbor’. The best-effort JSON decode is not included: it is per-datum CPU that would dominate a batch this endpoint exists to keep cheap. Served by YACI direct SQL with no provider fallback.

}Authorizations
API key (programmatic access — recommended)
Send your API key in the X-Api-Key header. Keys start with nxs_ and are
created in the dashboard (or via POST /api/keys with a session JWT).
Each key is scoped to one chain and one network (for example
CARDANO_MAINNET), fixed at creation time. It cannot query a different network
on the same chain, and it cannot query a different chain at all. A mismatched
network parameter returns 400 Network Mismatch. Create one key per chain
and network under the same account.
This is the credential most integrations should use.
Query Parameters
Accepts either the value listed here (CARDANO_MAINNET) or its kebab-case alias (cardano-mainnet); matching is case-insensitive. Omit it and the network is taken from the API key. A value that disagrees with the key's own network returns 400 Network Mismatch.
CARDANO_MAINNET, CARDANO_PREPROD, CARDANO_PREVIEW, APEX_PRIME_MAINNET, APEX_VECTOR_MAINNET, APEX_VECTOR_TESTNET, MIDNIGHT_MAINNET, MIDNIGHT_PREPROD, MIDNIGHT_STAGENET, BITCOIN_MAINNET, BITCOIN_TESTNET4 Body
