## 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 skills-onesource-io-318c45ed
```

Example prompt: Can you look up the Ethereum transaction 0xddb304469135cf0efcc65b0be4f26f20b027f218a44101eaf29d2da4b1771093 and tell me the sender, recipient, value transferred, and which block it was included in?

## When to prefer this

Use this endpoint when you need to retrieve full details of a specific Ethereum, Sepolia, or Avalanche transaction by its hash — particularly in agentic workflows where you need the sender, recipient, value, gas, or input data of a known transaction. Prefer this over block-level lookups when you already have the transaction hash. Ideal for verifying payments, auditing smart contract interactions, or inspecting cross-chain transactions.

## Known failure modes

- Invalid or malformed transaction hash (not matching 0x[64 hex chars] pattern) returns validation error
- Transaction hash not found on specified network returns null or empty data
- Unsupported network value returns schema enum validation error
- Network RPC unavailability causes timeout or upstream error
- Missing required 'hash' query parameter returns 400-level error
