## 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 algovoi-mpp-probe-compliance-aware-crypto-payment-probe-1781d548 -d '<json body>'
```

Example prompt: I need to send a compliant crypto payment to a merchant — run a compliance-screened MPP probe through AlgoVoi and give me back the transaction ID and receipt so I can confirm the payment went through.

## When to prefer this

Choose this endpoint when you need a compliance-aware crypto payment that includes sanctions screening and KYB gating out of the box, especially in agentic commerce flows using the MPP or x402 protocol. Prefer it over generic crypto payment endpoints when an audit trail across multiple blockchains and regulatory compliance are required for the transaction.

## Known failure modes

- Sanctions match on payer or payee — payment blocked with compliance rejection
- KYB gate not passed — merchant or user identity unverified, payment refused
- Insufficient USDC balance — payment cannot be funded
- Invalid or malformed body/queryParams — 400 bad request
- Blockchain network congestion — delayed or failed transaction confirmation
- Unsupported payment protocol version — protocol mismatch error

## How this service works

Compliance-aware crypto payment gateway with sanctions screening, KYB gating and a write-once audit chain across seven blockchains and four agent payment protocols (x402, MPP, AP2, A2A). Drop-in storefront plugins for merchants, a non-custodial Chrome extension wallet for users.

## Output

Returns a JSON object containing a transaction ID (tx_id), a payment receipt (receipt), and a resource ID (resource_id) confirming the probe payment was processed and logged on the audit chain.
