Real-time XLM (Stellar Lumens) price data via x402 micropayment on Base network.
What it does
This endpoint returns the current price of XLM (Stellar Lumens) as a pay-per-call API secured by the x402 protocol. It is part of a broader suite of finance, analytics, AI, and utility APIs hosted at lowpaymentfee.com, all priced at $0.02 per request with no API keys, rate limits, or subscriptions required.
Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). The x402 challenge specifies a maxAmountRequired of 20,000 base units, which at 6 decimals for USDC equals $0.02 per call. The endpoint accepts POST requests and returns JSON. No authentication beyond the x402 payment header is needed.
Documentation on the site is extremely sparse — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The endpoint is confirmed live (returns 402 with a valid x402 challenge), but the exact response format for a successful paid request must be inferred from the endpoint path and the broader site context (crypto token price data).

Quality
The endpoint is confirmed live with a valid x402 402 challenge, pricing is clear ($0.02 USDC on Base), and the purpose is inferable from the URL path. However, there is no OpenAPI spec, no documented request/response schema, no example payloads, and the site's docs pages are empty beyond a wallet connect prompt. Significant inference is required.
