## 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 x402-secure-api-staging-t54-ai-4dd35f59 -d '<json body>'
```

Example prompt: Before my AI agent submits this Solana USDC payment, verify the Verifiable Intent evidence and x402 payment binding to confirm the intent is legitimate and properly bound.

## When to prefer this

Use this endpoint when an AI agent needs to verify the authenticity and binding of a Verifiable Intent with an x402 Solana payment before executing a payment — specifically in agentic workflows on Solana where preventing unauthorized or spoofed payments is critical. Prefer this over generic signature verification when you need x402-specific protocol validation combined with intent binding checks.

## Known failure modes

- Invalid or malformed Verifiable Intent evidence returns a validation failure
- Mismatched x402 payment binding returns a binding error
- Unsupported Solana network or chain configuration returns an error
- Missing required fields in the request body returns a 400 bad request
- Payment amount or token mismatch returns a binding verification failure
- Network timeout or Solana RPC unavailability returns a service error

## How this service works

Verify Verifiable Intent evidence and Solana x402 payment binding before an agent payment. Price: $0.1 USDC (Solana)

## Output

Returns a verification result indicating whether the Verifiable Intent evidence is valid and whether the Solana x402 payment binding is correctly associated with the intent, allowing or blocking the agent payment accordingly.
