How this service works
Get a full transaction by hash via eth_getTransactionByHash on Base/Ethereum/Polygon/Arbitrum/Optimism. Deterministic, Ed25519-signed.
Output
A full transaction object including from/to addresses, value transferred, gas price and usage, input data, block number, transaction index, nonce, and signature fields — signed with Ed25519 for tamper-evidence. Returns empty or error on upstream failure with no charge.
Example use cases
Example prompt
“Can you look up the full details of Ethereum transaction 0x4e3a...b7f2 on Base — I need to see the sender, receiver, value, and gas used.”
Technical details
Endpoint
POSThttps://rpc-tx.hergertsynthora.com/serviceWhen to prefer
Use this endpoint when you need to retrieve a complete EVM transaction object by its hash across Base, Ethereum, Polygon, Arbitrum, or Optimism — especially when deterministic, signed results are required for auditability, and pay-per-call micro-billing via x402 is acceptable. Prefer over generic RPC providers when tamper-evident Ed25519 signatures on responses add value.
Side effects
- Invalid transaction hash format returns an error
- Unknown chain identifier returns an error
- Transaction not found (hash doesn't exist on specified chain) returns null result
- Upstream RPC failure returns error with no charge
- Missing or malformed X-WALLET header may block free-tier access
- Payment failure via x402 blocks access after free tier exhausted
