Plainsight x402 Payment Preflight
x402
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 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.
Example use cases
Pre-pay route validation for agent
“Before my agent sends a payment to the /v1/research route, can you do a preflight check to confirm it's properly listed, has a USD price set, and the payTo wallet has a live USDC balance?”
Whole-shop x402 readiness audit
“Can you run a bare preflight on the Plainsight shop to see if all the routes are payable, the USDC wallet is funded, and settlements have been happening over the last month?”
Stale endpoint detection before billing
“I want to know if the /v1/gas endpoint is actually settling — can you check its 30-day settlement gap and confirm it hasn't gone dark before I build a payment flow around it?”
Technical details
Endpoint
GEThttps://shop.netlobo.com/preflight/x402?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
