# APEX Faucet Arc Payment Inspector

> APEX Faucet Arc Payment Inspector is a paid API for AI agents from apexfaucet.xyz, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-03).

Inspects an Arc blockchain transaction hash as a payment and returns token data (symbol, holders, price) along with payment tier and asset details.

## Facts

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 apex-faucet-arc-payment-inspector-1a423dab
```

Example prompt: Can you check Arc transaction hash 0xabc123...def456 to see if it counts as a valid payment and tell me the APEX token price and holder count?

## When to prefer this

Use this endpoint when you need to inspect a specific Arc blockchain transaction hash to verify it as a payment and simultaneously retrieve APEX token metadata (price, holders). It is uniquely suited to the Arc/APEX ecosystem and combines payment validation with token analytics in a single call.

## Known failure modes

- Invalid or malformed tx hash returns error or ok:false
- Transaction not found on Arc network
- Transaction exists but was not a recognized payment
- Network timeout or Arc RPC unavailability
- Stale or already-processed transaction hash rejected

## How this service works

Did that Arc payment actually land? Pass ?tx=0x… and optionally ?to=0x… and ?expect=1.50 to get the payer, the amount, whether it reached your address, confirmations, finality and the gas paid — all in USDC. Handles the thing that breaks most Arc integrations: USDC is the NATIVE gas token at 18 decimals in tx.value AND has a 6-decimal ERC-20 view, so a verifier that only reads Transfer logs reports real payments as zero. Read-only: checking never consumes the payment.

## Output

Returns a JSON object with: ok (boolean success flag), data (object containing token symbol, holder count, and USD price), paid (numeric amount paid), tier (payment tier string like 'cheap'), and asset (payment asset name like 'USDC').
