Get the current ICP token price via x402 micropayment on Base for $0.02 per request.
What it does
This endpoint returns the current price of the ICP (Internet Computer) token. It is part of a broader suite of pay-per-call APIs hosted at lowpaymentfee.com, covering data analytics, AI/ML inference, finance/Web3 data, and utility services. All endpoints use the x402 protocol for payment, settling in USDC on the Base network.
The specific endpoint `/api/v1/tokens/ICP/price` accepts POST requests and returns JSON. The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base), which equals $0.02 per request (USDC uses 6 decimals). No API keys or accounts are needed — payment is handled entirely via the X-PAYMENT header in the x402 flow.
Documentation on the site is extremely sparse. The docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional content. There is no OpenAPI schema, no request/response examples, and no detailed documentation for any endpoint. The endpoint is confirmed live (returns a proper 402 challenge), but the exact response format and any supported query parameters are unknown.

Quality

However, there is no OpenAPI schema, no request/response examples, and all documentation pages are empty stubs. The exact response format and supported parameters are entirely unknown.
