SNX token data via x402 micropayment on Base — $0.02 per request, no API key needed.
What it does
This endpoint at lowpaymentfee.com provides token data for SNX (Synthetix Network Token) as part of a broader suite of finance, crypto, AI, and utility APIs. All endpoints on the platform use the x402 payment protocol, settling in USDC on the Base network. Each request costs $0.02 (20,000 base units of USDC with 6 decimals), and there are no API keys, rate limits, or subscription commitments — callers simply attach an x402 payment header to each request.
The specific endpoint `/api/v1/tokens/SNX` sits alongside other crypto and finance endpoints such as `/api/v1/crypto/quotes`, `/api/v1/finance/prices`, and `/api/v1/finance/rates`. While the exact response schema for this token endpoint is not documented, it is reasonable to infer it returns JSON data about the SNX token (likely price, market data, or metadata) given the platform's finance and crypto API category.
The endpoint is live and returns a proper x402 challenge (HTTP 402) when called without payment. It accepts POST requests and settles payments to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` using USDC (`0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`) on Base. The maximum timeout for payment settlement is 300 seconds. Documentation on the site is extremely sparse — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no additional technical detail.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no documentation, no OpenAPI schema, no example responses, and no description of what the /tokens/SNX endpoint actually returns. The docs, pricing, and API pages are all blank beyond a wallet-connect prompt. Pricing is clear ($0.02/request) but the response format is entirely unknown.
