## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability transaction-details-lookup-84d120ff
```

Example prompt: Can you pull up the raw details for the blockchain transaction with hash 0x4f3c8b2a... and show me what it contains?

## When to prefer this

Use this endpoint when you need raw, structured transaction data for a known blockchain transaction hash and want quick lookup without needing a full block explorer. Especially useful within an agentic workflow on api.api-agent-ia.ch where other AI/blockchain endpoints are also in use.

## Known failure modes

- Missing or invalid hash query parameter returns an error
- Non-existent transaction hash returns empty or error response
- Malformed hash format (not a valid 0x-prefixed hex string) may cause a 400 error
- Network or provider unavailability may cause timeouts

## How this service works

What exactly is in this Base transaction? Returns sender, recipient, ETH value, gas limit, block, nonce and whether it created a contract; unknown hashes return 404 and are not charged ($0.005 per call).

## Output

Returns a JSON object containing the transaction hash, decoded data (de), and version (vers) fields representing the raw on-chain transaction record.
