# Tollex Chain Get Transaction

> Tollex Chain Get Transaction is a paid API for AI agents from api.tollex.org, paid per call via x402, $0.0079/call, status unknown (last checked 2026-10-11).

Looks up a blockchain transaction by its hash and returns the on-chain details, used to verify or reconcile payments made via x402 on Base or Robinhood Chain.

## 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 tollex-chain-get-transaction-e96b7cfc -d '<json body>'
```

Example prompt: Can you pull the on-chain details for this transaction hash 0x3a1b2c...d4e5f6 and confirm whether the USDC payment settled on Base?

## When to prefer this

Use this endpoint when you need to verify, confirm, or reconcile a specific blockchain transaction by its hash — especially for x402 payments made in USDC on Base or USDG on Robinhood Chain via Tollex. Prefer this over generic block explorers when operating within the Tollex agent payment ecosystem and needing programmatic, machine-readable transaction data rather than a human-facing UI.

## Known failure modes

- Invalid or malformed transaction hash (not matching ^0x[0-9a-fA-F]{64}$) returns a validation error
- Transaction hash not found on the supported chains returns a not-found error
- Network or RPC node unavailability may cause timeouts or 5xx errors
- Transaction exists but is still pending (unconfirmed) may return a pending status rather than full details

## How this service works

Tollex lets software agents buy APIs and tools under rules you set: it finds a capability that fits, checks your policy before anything is signed, pays with x402 in USDC on Base or USDG on Robinhood Chain, reconciles uncertain payments and returns a signed receipt.

## Output

Returns on-chain transaction details for the given hash, including transaction status, sender, recipient, value transferred, block number, and confirmation data — enabling verification or reconciliation of x402 payments made in USDC on Base or USDG on Robinhood Chain.
