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 #134 via an x402-gated POST request. It is part of a broader platform offering multiple API categories — data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities — all priced at $0.02 per call with no API keys, rate limits, or commitments required.
Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). The x402 challenge advertises a maxAmountRequired of 20,000 base units, which at 6 decimals equals $0.02. The endpoint accepts POST requests and returns application/json. The x402 version is 1 with an "exact" payment scheme and a 300-second timeout.
The specific endpoint `/api/v1/orders/134/status` appears to be an order-status lookup. However, the crawled documentation is extremely thin — the docs, API, pricing, and README pages all rendered only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema documentation, and no examples of what the order status response looks like. The platform lists many endpoints but provides no detailed documentation for any of them.
Capabilities
Use cases
- —Checking the status of a specific order programmatically
- —Integrating order tracking into an agent workflow with per-call payment
- —Demonstrating x402 micropayment protocol usage on Base
Fit
Best for
- —Agents needing simple order status lookups without API key management
- —Developers experimenting with x402 payment protocol
- —Low-volume, pay-as-you-go order status queries
Not for
- —High-volume order management systems needing bulk queries
- —Users who need detailed API documentation or response schema guarantees

Quick start
curl -X POST https://lowpaymentfee.com/api/v1/orders/134/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 spec, no request/response schema, no documentation beyond a wallet-connect prompt, and the endpoint is hardcoded to a single order ID with no explanation of what it returns. Effectively a stub listing.
Warnings
- —No API documentation available — docs, API, pricing, and README pages all show only 'Connect wallet'
- —No OpenAPI or output schema describing the response format
- —Endpoint is hardcoded to order ID 134; unclear if other order IDs are supported via different URLs
- —No request body schema documented
- —Platform lists many endpoints but none have detailed documentation
