Get the current price of RPL (Rocket Pool) token via a pay-per-call x402 endpoint on Base.
What it does
This endpoint returns the current price of the RPL (Rocket Pool) token. It is part of a broader suite of APIs offered by lowpaymentfee.com, which covers data analytics, AI/ML inference, finance/Web3 data, and utility services — all gated behind the x402 payment protocol on the Base network.
The endpoint accepts POST requests and returns JSON. Payment is settled in USDC on Base (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) at a cost of $0.02 per request (maxAmountRequired of 20,000 base units with 6 decimals). There are no API keys, no rate limits, and no subscription commitments — each call is paid individually via the X-PAYMENT header. The x402 challenge was successfully captured, confirming the endpoint is live.
Documentation beyond the landing page is sparse: the /docs, /pricing, /api, and /README pages all returned only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI schema, no example request/response payloads, and no detailed field documentation available from the crawl. The output format and exact fields returned are unknown and must be inferred from the endpoint name and the broader site context (token price data).
