## 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-payment-options-431f0939 -d '<json body>'
```

Example prompt: Before my agent buys access to https://merchant.example/v1/quote, check what payment options that merchant accepts — I want to know if it supports USDC on Base or USDG on Robinhood Chain.

## When to prefer this

Use this endpoint when an agent or orchestrator needs to inspect what payment methods a specific merchant supports before committing to a purchase — especially in policy-gated or multi-currency environments where compatibility must be confirmed first. Prefer this over guessing or attempting a payment blind, particularly when operating under spending rules that restrict which networks or currencies are allowed.

## Known failure modes

- Invalid or unreachable merchant URL returns an error or empty result
- Merchant URL does not implement x402 payment protocol — no options returned
- Malformed URL (not starting with http:// or https://) rejected by input validation
- Merchant server timeout leads to failed lookup
- URL exceeds 2048 character limit and is rejected

## 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 the payment options available at the specified merchant URL, including accepted stablecoins (USDC, USDG), supported blockchain networks (Base, Robinhood Chain), payment protocols (x402), and any other merchant-specific payment configuration details needed before initiating a transaction.
