Pay-per-call token data API for ALGO — $0.02 per request via x402 on Base.
What it does
This endpoint at lowpaymentfee.com provides premium API access to ALGO (Algorand) token data via a pay-per-request model using the x402 protocol. Payment is settled in USDC on the Base network at $0.02 per call (20,000 base units of USDC with 6 decimals). No API keys, rate limits, or subscriptions are required — each request is individually paid for via an X-PAYMENT header.
The endpoint is part of a broader platform offering dozens of pay-per-call APIs across categories including data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities — all priced uniformly at $0.02 per request. The specific `/api/v1/tokens/ALGO` path suggests it returns token-level data for Algorand, likely including price, market data, or metadata, though the exact response schema is not documented.
The x402 challenge is live and returns a valid 402 response with an "exact" payment scheme. The payment is directed to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` using USDC at contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` on Base. The timeout for payment settlement is 300 seconds. Documentation beyond the landing page is essentially empty (all doc/pricing/API pages just show "Connect wallet"), so the exact request format and response structure must be inferred.
