# AveDaris Delivery Proof Verification

> AveDaris Delivery Proof Verification is a paid API for AI agents from api.avedaris.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-29).

Retrieves a cryptographic delivery proof confirming that a paid agent service was actually delivered via the x402 protocol

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 avedaris-delivery-proof-verification-486932be
```

Example prompt: Can you pull the delivery proof for the agent-utility-network service I just paid for, so I can confirm the x402 delivery actually went through?

## When to prefer this

Use this endpoint when you need to cryptographically confirm that an x402-paid agent service was actually delivered — particularly in autonomous workflows where payment and delivery must be independently verified before proceeding. Prefer this over trusting the originating service's own status response, or when building audit trails for agent-to-agent micropayment transactions on the AveDaris network.

## Known failure modes

- Missing or invalid payment reference returns an empty or error response
- Undelivered service returns delivered: false
- Stale or expired transaction references may return no proof
- Network or upstream errors return 5xx responses
- Malformed query parameters result in 400-level errors

## How this service works

Test that your x402 client can pay AUN: one call returns a deterministic paid receipt that the purchase was delivered (a liveness check, not downstream business-value proof). Use it as a first test call; once it works, the same client and wallet can call vendor-intelligence (company research), domain-trust-score or web-read-batch with no setup. $0.001 USDC per call on Base.

## Output

Returns a JSON object containing the service name (e.g. 'agent-utility-network'), the utility type (e.g. 'delivery.proof'), the protocol used ('x402'), and a boolean 'delivered' field confirming whether the service was successfully delivered.
