# ScanPay Payment Reconcile

> ScanPay Payment Reconcile is a paid API for AI agents from scanpay-edge.alextaghiashvili.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-11-02).

Verifies a Base USDC on-chain transaction against an expected invoice, checking amount, recipient, asset type, and confirmation status.

## 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 scanpay-payment-reconcile-d76409e8
```

Example prompt: Can you verify whether the Base USDC transaction 0x3a7f...d291 actually paid $25.00 to the recipient address 0xBbBb...bBbB, and confirm it has at least 1 confirmation?

## When to prefer this

Use this endpoint when you need to programmatically verify that a specific Base USDC on-chain transaction satisfies an invoice — specifically checking recipient address, USD amount, asset type, and confirmation count in a single call. Prefer this over manual block explorer lookups when automating payment gating, order fulfillment workflows, or agent-to-agent settlement verification on the Base network.

## Known failure modes

- Invalid tx_hash format (must be 0x + 64 hex chars) returns validation error
- Transaction not yet indexed or not found on Base returns null/empty tx fields
- Insufficient confirmations results in confirmation_state: pending and discrepancy flag
- Amount or asset mismatch reflected in discrepancies array with matches: false
- Invalid recipient address format (not 0x + 40 hex chars) returns schema validation error
- expected_amount_usd of 0 or above 100000 is rejected by schema constraints

## How this service works

Pay-per-call x402 APIs for AI agents: OpenAI-compatible LLM chat, perp funding and arbitrage spreads, crypto prices, gas, FX, Solana SPL mint audit, token price by contract, x402 delivery-receipt verification, web search, clean page extraction, batch tools and deterministic code-security scanning. USDC on Base or Solana, no signup, no API key, from $0.0001 a call.

## Output

Returns a JSON object containing: whether the transaction matches the invoice (matches: boolean), the transaction details (to, from, asset, status, value_usd, block_number, confirmations), the expected values (recipient, amount_usd, asset), a list of discrepancies (e.g. amount_mismatch, asset_mismatch, insufficient_confirmations), the chain (base), confirmation_state (pending/confirmed), and an observed_at_unix timestamp.
