Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-receipt-retrieval-cadd8c15 -d '<json body>'
```

Example prompt: Fetch the Tollex signed receipt for transaction ID 'rcp_X9kLmN3qPw7bT2vR' so I can confirm the USDC payment settled correctly.

## When to prefer this

Use this endpoint when you need to retrieve and verify a specific, already-executed Tollex payment transaction. It is the right choice for auditing agent spending, reconciling uncertain or in-flight payments, or producing proof-of-purchase receipts for a known receipt ID. Prefer this over generic payment lookup tools when the transaction was made through Tollex's x402 protocol on Base or Robinhood Chain.

## Known failure modes

- Receipt ID not found (invalid or expired ID returns 404-style error)
- Malformed receipt ID pattern fails schema validation (must match ^[A-Za-z0-9_-]{8,128}$)
- Payment still pending — receipt not yet finalized
- Insufficient funds or payment failed — no receipt generated
- Network or blockchain confirmation lag causing temporary unavailability

## 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 a signed receipt object confirming the completed Tollex payment transaction, including payment amount in USDC or USDG, the chain used (Base or Robinhood Chain), policy-check status, and a cryptographic signature verifying settlement.
