Get blockchain-specific transaction JSON.

GET

https://optimism-index.nownodes.io/api/v2/tx-specific/{txid}

Authorizations

ApiKeyAuthApiKeyAuth

api-key string

NOWNodes API key passed in the api-key header.

Returns transaction data in the exact backend-specific format. Use this when a chain exposes fields that are intentionally absent from the normalized Tx schema.

Load estimate: Medium; payload size depends on chain-specific fields and transaction complexity.

Parameters

txidstringrequiredpath

Transaction id/hash.

Response

200OK

Chain-specific transaction payload.

401Unauthorized

Unauthorized: API key is present but rejected by the NOWNodes gateway.

405Method Not Allowed

Method Not Allowed. Returned by the NOWNodes gateway for malformed or unsupported gateway-level requests.

422Unprocessable Entity

Missing API key. The NOWNodes gateway returns plain text for this error.

Public API error.
