Check order status via x402 micropayment on Base (USDC, $0.02/request).
What it does
This endpoint at lowpaymentfee.com returns the status of order #76 via a POST request, gated by the x402 payment protocol. It is part of a broader platform offering data & analytics, AI/ML inference, finance/Web3, and infrastructure utility APIs — all priced at $0.02 per request, settled in USDC on the Base network.
The specific endpoint `/api/v1/orders/76/status` accepts POST requests and requires an X-PAYMENT header containing a valid x402 payment proof. The x402 challenge confirms the endpoint is live, advertising a maxAmountRequired of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is sent to address 0x1A2B…85F3 with a 300-second timeout.
The platform advertises no API keys, no rate limits, and instant access. Documentation pages (/docs, /pricing, /api) appear to require a wallet connection and contain no additional readable content. There is no OpenAPI schema, no detailed request/response documentation, and no examples beyond the x402 challenge itself. The endpoint path suggests it returns JSON (mimeType: application/json) with order status information, but the exact response schema is unknown.
Capabilities
Use cases
- —Checking the status of a specific order programmatically with per-request micropayment
- —Integrating x402-gated order lookups into agent workflows
- —Demonstrating x402 protocol payment flows on Base network
Fit
Best for
- —Agents or services that need on-demand order status without subscription commitments
- —Developers experimenting with x402 micropayment protocol on Base
- —Low-volume, pay-as-you-go API consumption
Not for
- —High-volume order tracking where subscription pricing would be cheaper
- —Users who need detailed API documentation or OpenAPI specs before integrating
- —Querying arbitrary order IDs (this endpoint is hardcoded to order 76)
Quick start
curl -X POST https://lowpaymentfee.com/api/v1/orders/76/status \
-H "X-PAYMENT: <x402-payment-proof>" \
-H "Content-Type: application/json"Endpoint
Quality
The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no request/response examples, and documentation pages are empty (wallet-gated). The endpoint is scoped to a single hardcoded order ID (76), limiting general utility. Effectively a stub listing.
Warnings
- —Endpoint path is hardcoded to order 76 — unclear if other order IDs are supported or if this is a demo
- —No OpenAPI or response schema available; response format is unknown
- —All documentation pages (/docs, /pricing, /api, /README) require wallet connection and provide no readable content
- —Platform appears to be a demo or showcase site; actual data backing these APIs is unverified
