Fetch RPL token data via x402 micropayment on Base for $0.02 per request.
What it does
This endpoint at lowpaymentfee.com returns token data for RPL (Rocket Pool) via the x402 payment protocol. It is part of a broader suite of pay-per-call APIs offered by the same provider, spanning data analytics, AI/ML inference, finance/Web3 market data, and utility services. All endpoints on the platform share a uniform $0.02-per-request pricing model settled in USDC on the Base network.
The specific endpoint `/api/v1/tokens/RPL` accepts POST requests and returns JSON. Payment is handled inline via the x402 protocol: callers attach an `X-PAYMENT` header containing a signed USDC payment of up to 20,000 base units (i.e., $0.02, since USDC uses 6 decimals) to the provider's address on Base. No API keys, accounts, or rate limits are advertised — access is gated purely by micropayment.
Documentation beyond the landing page is extremely sparse. The docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of what fields the RPL token endpoint actually returns. The endpoint is confirmed live (returns a valid 402 challenge), but the exact response schema and supported query parameters are unknown.

Quality
The endpoint is confirmed live with a valid x402 402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI spec, no documented request/response schema, no example payloads, and all documentation pages render only a wallet-connect prompt. The actual data returned is entirely unknown.
