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 #116 via a POST request, gated behind an x402 payment challenge. It is part of a broader platform (lowpaymentfee.com) that offers a variety of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and utility services — all priced at $0.02 per request and settled in USDC on the Base network.
The specific endpoint `/api/v1/orders/116/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 (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base), which equals $0.02 given USDC's 6 decimals. No API keys are required; callers authenticate purely via the X-PAYMENT header containing a signed payment proof. The endpoint responds with application/json.
The platform advertises no rate limits, no minimums, and instant access. Documentation pages (/docs, /pricing, /api, /README) all resolve but appear to require a wallet connection to render content, so detailed request/response schemas are not available from the crawl. The broader site lists additional endpoints for sentiment analysis, text summarization, classification, embeddings, price feeds, exchange rates, geocoding, and more — all at the same $0.02 price point.
Capabilities
Use cases
- —Checking the status of a specific order programmatically with per-call payment
- —Integrating order tracking into an agent workflow without managing API keys
- —Demonstrating x402 payment protocol integration on Base network
Fit
Best for
- —Developers experimenting with x402 payment protocol
- —Agents that need keyless, pay-per-call API access
- —Low-volume order status lookups without subscription commitments
Not for
- —High-volume order management systems needing bulk queries at lower cost
- —Users who need detailed API documentation before integrating
- —Applications requiring order status for arbitrary order IDs (this endpoint is hardcoded to order 116)
Quick start
curl -X POST https://lowpaymentfee.com/api/v1/orders/116/status \
-H "X-PAYMENT: <x402-payment-proof>" \
-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 request/response examples, and the docs pages all require wallet connection to render. The endpoint appears to be for a single hardcoded order ID (116), making its general utility unclear.
Warnings
- —Documentation pages (/docs, /pricing, /api, /README) require wallet connection and returned no useful content during crawl
- —No OpenAPI or request/response schema available — input and output formats are unknown
- —Endpoint path is hardcoded to order 116; unclear if other order IDs are supported or if this is a demo
- —The platform lists many endpoints but none have detailed documentation visible without wallet auth
