TON liquidity data via x402 micropayment on Base — $0.02 per request, no API key needed.
What it does
This endpoint at lowpaymentfee.com provides DeFi liquidity data for the TON blockchain. It is part of a broader platform offering data, analytics, AI, finance, and infrastructure APIs, all gated behind the x402 payment protocol. Each call costs $0.02 in USDC on the Base network — no API keys, no rate limits, and no subscriptions required.
The endpoint accepts POST requests and returns JSON. The x402 challenge confirms the endpoint is live, accepting payments to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on Base. The maxAmountRequired of 20000 base units (USDC has 6 decimals) equals $0.02 per request.
Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what fields the liquidity endpoint accepts or returns. The endpoint's specific input parameters and output format must be discovered experimentally. Given the DeFi/TON context, it likely returns liquidity pool data (TVL, pool addresses, token pairs, volumes), but this is inference, not confirmed.

Quality
The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no request/response examples, and all documentation pages returned only a wallet-connect prompt. The endpoint's input parameters and output format are entirely unknown.
Warnings
- —No API documentation available — docs, pricing, and README pages all render only a 'Connect wallet' prompt with no content.
- —No OpenAPI or JSON schema for request or response bodies; input parameters are unknown.
- —Endpoint purpose (TON liquidity) is inferred from the URL path only; no authoritative description exists.
- —The broader platform lists many endpoints across diverse categories (AI, geocoding, finance) all at $0.02 — quality and depth of each is unverified.
