# Plainsight x402 Payment Preflight

> Plainsight x402 Payment Preflight is a paid API for AI agents from shop.netlobo.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-12).

Checks whether a specific route (or the entire shop) is payable via x402 — verifying it is listed, priced, backed by a funded USDC wallet, and actively settling payments.

## 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 plainsight-x402-payment-preflight-5f0b4952
```

Example prompt: Before I pay anything, can you preflight-check the /v1/gas route on the Plainsight shop to confirm it's listed, priced, and that the USDC wallet behind it is actually funded and has been settling in the last 30 days?

## When to prefer this

Use this endpoint when an AI agent or developer needs to validate an x402 payment route before committing funds — especially to confirm the payTo wallet is live and funded, the route is priced and listed, and real settlements have occurred recently. Prefer this over blindly attempting a payment when reliability and fund safety matter, or when building an agent that needs to programmatically discover and vet x402 endpoints before routing tasks to them.

## Known failure modes

- Route not found in catalog — in_catalog: false returned
- Wallet has zero or insufficient USDC balance — wallet_ok: false
- No settlements in 30-day window — gap_30d may be null or very large
- Invalid or malformed route path — query param parsing error
- Shop is entirely unlisted or misconfigured — status: fail across all routes
- Network RPC unavailable — live balance read may fail with 5xx

## How this service works

Per-call data and LLM products, paid in USDC on Base via x402. No accounts, no API keys: each request returns 402 with a payment challenge.

## Output

A JSON object containing: overall pass/fail status, the pay-to wallet address, USDC asset address, live USDC wallet balance in USD, network (e.g. eip155:8453 for Base), and per-route details including whether the route is in the catalog, whether it is priced, its USD price, 30-day knock count, 30-day settlement count, and settlement gap. Also includes the timestamp of the check.
