THETA liquidity data via x402 micropayment on Base network for $0.02/request
What it does
This endpoint provides DeFi liquidity data for the THETA token, accessible through the x402 payment protocol on the Base network. It is part of a broader suite of APIs offered by lowpaymentfee.com covering data analytics, AI/ML inference, finance/Web3, and infrastructure utilities. Each request costs $0.02 in USDC, paid per-call with no API keys, rate limits, or subscriptions required.
The endpoint accepts POST requests and returns JSON. The x402 challenge confirms the endpoint is live, settling payments in USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on the Base L2 network. The max amount required is 20,000 base units of USDC (6 decimals), which equals $0.02. Payment is made via the x402 X-PAYMENT header, with a timeout of 300 seconds.
Documentation is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no detailed description of what fields the THETA liquidity endpoint returns. The endpoint's specific functionality (e.g., pool TVL, depth, volume) must be inferred from the URL path alone.

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 are empty beyond a wallet-connect prompt. The specific data returned by this endpoint is entirely unknown.
Warnings

- —No OpenAPI or JSON schema describing request parameters or response fields
- —Endpoint functionality (what liquidity data fields are returned) is inferred solely from the URL path
- —The broader lowpaymentfee.com site lists many diverse API categories; unclear if all are fully implemented or stubs
