# Tollex Merchant Inspect

> Tollex Merchant Inspect 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).

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-merchant-inspect-65f9785c -d '<json body>'
```

Example prompt: Before committing to any payment, check what the merchant at https://merchant.example/v1/quote actually offers — I want to see its capabilities, price, and whether it fits my policy rules.

## When to prefer this

Use this endpoint when an agent or orchestration layer needs to evaluate a merchant API before committing payment — especially to check pricing, capabilities, and policy compliance in a single lookup. Prefer this over blindly calling an unknown endpoint when budget governance or audit trails matter.

## Known failure modes

- Invalid or non-HTTPS URL returns a validation error
- Merchant URL is unreachable or times out
- Merchant does not expose x402-compatible metadata, returning an empty or partial result
- Malformed merchant response that cannot be parsed into a structured capability description
- Rate limiting or quota exceeded on the Tollex side

## 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 structured metadata about the merchant endpoint at the given URL, including its capability description, pricing (likely in USDC), supported payment protocols, and any policy-relevant signals that allow the caller to decide whether to proceed with a purchase.
