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 #178 via a POST request, gated by an x402 payment challenge. It is part of a broader platform that offers dozens of pay-per-call API endpoints across data analytics, AI/ML inference, 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/178/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 sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout. No API keys or rate limits are advertised; access is granted purely through the x402 payment header.
The broader platform also lists endpoints for sentiment analysis, text summarization, classification, embeddings, price feeds, exchange rates, token quotes, gas estimates, geocoding, validation, conversion, and generation — all at the same $0.02 price point. However, no OpenAPI schema, detailed documentation, or example responses were found in the crawl. The docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no substantive content.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing. However, there is no OpenAPI schema, no documentation, no example responses, and the endpoint is hardcoded to a single order ID (178). The crawled docs/pricing/API pages were all empty beyond a wallet connect prompt.
Warnings
- —Endpoint is hardcoded to order #178 — unclear if other order IDs are supported or if this is a demo
- —No OpenAPI schema or response schema available; response format is unknown
- —All documentation pages (docs, API, pricing, README) returned only 'Connect wallet' with no content
- —The broader platform advertises many endpoints but none have documented schemas or examples
