Real-time SOL token price via x402 micropayment on Base for $0.02 per request.
What it does
This endpoint returns the current price of the SOL (Solana) token, accessible via the x402 payment protocol. It is part of a broader suite of paid APIs offered by lowpaymentfee.com, covering data analytics, AI/ML inference, finance/Web3 data, and utility services. Each request costs $0.02 (20,000 base units of USDC on the Base network, where USDC has 6 decimals). No API keys or rate limits are required — callers simply attach an x402 payment header to each POST request.
The endpoint is live and returns a standard x402 402 challenge when called without payment. It accepts the "exact" payment scheme, settling in USDC (contract 0x8335…2913) on the Base L2 network, with a 300-second payment timeout. The response MIME type is application/json. The specific output schema for the price data is not documented beyond the MIME type, so the exact shape of the JSON response body must be inferred or discovered by making a paid call.
The provider's landing page lists uniform $0.02 pricing across all endpoints and advertises no API keys, no rate limits, and instant access. Documentation pages (/docs, /pricing, /api, /README) appear to be behind a wallet-connect gate and yielded no additional technical content during the crawl.

Quality
The endpoint is live (402 challenge captured) with clear pricing ($0.02/request in USDC on Base). However, there is no OpenAPI schema, no documented response format, and all docs pages are gated behind wallet-connect with no accessible content. The response body shape is unknown.
Warnings
- —No OpenAPI or response schema available — the exact JSON response structure is undocumented.
- —All documentation pages (/docs, /pricing, /api, /README) returned only a wallet-connect prompt with no technical content.
- —The provider offers many endpoints across diverse categories (AI, analytics, finance, utilities) all at the same $0.02 price — the actual data sources and quality behind each are unverified.
