Real-time DOT token price via x402 micropayment on Base for $0.02 per request.
What it does
This endpoint returns the current price of the DOT (Polkadot) token. It is part of the lowpaymentfee.com platform, which offers a suite of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and utility services. All endpoints use the x402 payment protocol, settling in USDC on the Base network.
The specific endpoint at `/api/v1/tokens/DOT/price` accepts POST requests and returns JSON. The x402 challenge advertises a maximum cost of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 per request (USDC uses 6 decimals). No API keys are required; payment is handled inline via the X-PAYMENT header. The platform advertises no rate limits and instant access.
Documentation beyond the landing page is sparse — the /docs, /pricing, and /README pages all returned only a "Connect wallet" prompt with no substantive content. There is no OpenAPI spec or detailed schema describing the response format. The endpoint is confirmed live (HTTP 402 challenge captured), but the exact response fields for a successful paid request are not documented in the crawled material.

Quality
The endpoint is confirmed live with a valid x402 402 challenge and clear pricing ($0.02 USDC on Base). However, there is no OpenAPI spec, no response schema, no example responses, and all documentation pages returned only a wallet-connect stub. The listing is largely inferred from the landing page and the x402 challenge.
