Check order status via x402 micropayment on Base network for $0.02 per request.
What it does
This endpoint at lowpaymentfee.com returns the status of order #173 via a POST request, gated behind an x402 payment challenge. It is part of a broader platform (lowpaymentfee.com) that offers a variety of API categories — data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities — all priced at $0.02 per request and settled in USDC on the Base network.
The specific endpoint `/api/v1/orders/173/status` is labeled "Premium API Access" in the x402 challenge. The payment scheme is "exact" with a maxAmountRequired of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is made via the X-PAYMENT header per the x402 protocol, with no API keys or rate limits required. The challenge specifies a max timeout of 300 seconds.
The platform advertises a simple pay-per-use model with no minimums, no commitments, and no API keys. Documentation pages (/docs, /pricing, /api, /README) all appear to require wallet connection and contain no additional content in the crawl. As a result, the actual response schema and detailed behavior of this endpoint are unknown — only the x402 challenge metadata is available.
Capabilities
Use cases
- —Checking the status of a specific order (#173) programmatically
- —Demonstrating x402 protocol payment flows on Base
- —Agent-driven order tracking with per-request micropayments
Fit
Best for

- —Agents that need to query order status with crypto micropayments

Quick start
curl -X POST https://lowpaymentfee.com/api/v1/orders/173/status \
-H "X-PAYMENT: <x402_payment_token>" \
-H "Content-Type: application/json"Endpoint
Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no documented request/response format, no examples, and all documentation pages behind wallet-connect walls returned no useful content. The endpoint path is hardcoded to a single order ID (173), making its general utility unclear.
Warnings
- —No response schema or example responses available — actual output format is unknown
- —All documentation pages (/docs, /pricing, /api, /README) returned only 'Connect wallet' with no substantive content
- —Endpoint path is hardcoded to order 173; unclear if this is a demo or a real order-tracking system
- —No OpenAPI spec or ai-plugin manifest found
