Real-time SNX token price via x402 micropayment on Base for $0.02 per request.
What it does
This endpoint returns the current price of the SNX (Synthetix) 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/SNX/price` accepts POST requests and returns JSON. The x402 challenge advertises a maximum cost of 20,000 base units of USDC (0x8335…0913 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 extremely sparse — the /docs, /pricing, /api, and /README pages all returned only a "Connect wallet" prompt with no substantive content. There is no OpenAPI spec, no example request/response payloads, and no detailed documentation for the token price endpoint specifically. The response schema must be inferred: it likely returns a JSON object with the token symbol and its current price, but this is unconfirmed.
