x402-gated order status endpoint on Base, pay-per-call with USDC.
What it does
This endpoint at lowpaymentfee.com provides access to order status information via the x402 payment protocol. The specific resource `/api/v1/orders/94/status` returns order status data for order ID 94 in JSON format, gated behind a per-request USDC micropayment on the Base network.
The endpoint accepts POST requests and requires an X-PAYMENT header conforming to x402 version 1. The maximum amount required per call is 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimal places. Payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a timeout of 300 seconds.
lowpaymentfee.com hosts a broader suite of x402-gated APIs spanning data & analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation) — all priced at $0.02 per request. No API keys, rate limits, or commitments are required. However, the crawled documentation pages (docs, pricing, README) returned only a "Connect wallet" prompt with no substantive content, so the actual response schema and detailed behavior of this specific order-status endpoint remain undocumented.

Quality
The x402 challenge is live and well-formed, confirming the endpoint exists and its pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no response examples, no documentation beyond a wallet-connect prompt, and the endpoint path is specific to a single order ID (94), making its general utility unclear. Effectively a stub listing.
Warnings
- —No API documentation available — docs, pricing, and README pages all return only a 'Connect wallet' prompt.
- —No response schema or example response is provided; actual output format is unknown.
- —The endpoint path is hardcoded to order ID 94; it is unclear whether other order IDs are supported or how to discover them.
- —The broader site advertises many API categories (AI, finance, analytics, etc.) but none could be verified beyond their listing on the homepage.
