# TELAGO Verify x402 Delivery After Payment

> TELAGO Verify x402 Delivery After Payment is a paid API for AI agents from ozeejewwpjmabshxyitc.supabase.co, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-29).

Verifies that an x402 HTTP delivery was fulfilled after a Base USDC payment by checking the on-chain settlement receipt, payTo/amount match, and HTTP response status, returning PROVEN, INCOMPLETE, or CONFLICT.

## 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 telago-verify-x402-delivery-after-payment-6299f6ed
```

Example prompt: Can you verify that my x402 payment with transaction hash 0xabc123 was actually delivered — the payTo should be 0xSeller... and the expected atomic amount is 3000, and the HTTP response came back as 200?

## When to prefer this

Use this endpoint when you need to cryptographically attest that an x402 HTTP micropayment on Base USDC resulted in actual content delivery — especially for agent workflows that require proof-of-delivery before releasing funds or logging compliance records. Prefer this over manual receipt checks when you need a structured PROVEN/INCOMPLETE/CONFLICT verdict that can be acted on programmatically.

## Known failure modes

- Transaction hash not found on Base network — returns INCOMPLETE or error
- payTo address mismatch between expected and on-chain — returns CONFLICT
- Amount mismatch between expectedAmountAtomic and settled amount — returns CONFLICT
- HTTP response status indicates non-delivery (e.g. 402, 500) — returns INCOMPLETE or CONFLICT
- Invalid or malformed transaction hash — returns validation error
- Network latency causing unconfirmed settlement — returns INCOMPLETE

## How this service works

Verify x402 delivery after payment. Check Base USDC settlement receipt, exact payTo/amount, HTTP delivery status and return PROVEN, INCOMPLETE or CONFLICT.

## Output

Returns an attestation verdict of PROVEN (payment settled correctly and HTTP delivery succeeded), INCOMPLETE (payment or delivery not yet confirmed), or CONFLICT (mismatch between on-chain settlement and delivery status), along with supporting details about the settlement receipt, payTo/amount comparison, and HTTP response code.
