## 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 x402scan-send-transaction-821f90dc -d '<json body>'
```

Example prompt: Send a payment through the x402 ecosystem via x402scan — I want to pay for a resource endpoint using USDC right now.

## When to prefer this

Use this endpoint when you need to programmatically send a payment or transaction within the x402 protocol ecosystem, especially when interacting with x402-gated resources or sellers listed on x402scan. Prefer this over generic payment APIs when the recipient or resource specifically requires x402 protocol compliance.

## Known failure modes

- Insufficient USDC balance results in payment failure
- Invalid transaction payload format returns a 400 error
- Network or facilitator unavailability causes a timeout
- Unauthorized sender address returns a 401 or 403 error
- Malformed recipient or resource address returns a validation error

## How this service works

## Output

A confirmation response indicating whether the x402 transaction was successfully submitted, along with a transaction ID or receipt that can be used to track the payment in the x402 ecosystem explorer.
