DeFi liquidity data for TWT token, paid per-request via x402 on Base network.
What it does
This endpoint at lowpaymentfee.com provides DeFi liquidity data for the TWT (Trust Wallet Token) via a pay-per-call x402 protocol. The endpoint is live and returns a 402 challenge requiring payment in USDC on the Base network. The price per request is $0.02 (20,000 base units of USDC with 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof to access the data.
The provider (lowpaymentfee.com) hosts a broad catalog of pay-per-request APIs spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities, all priced at $0.02 per call. This specific endpoint sits under the Finance & Web3 category and focuses on liquidity information for the TWT token. The response MIME type is application/json. However, documentation beyond the landing page is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further technical detail.
Because there is no OpenAPI schema, no example request/response payloads, and no documentation describing the response fields or accepted request parameters, the actual data structure returned is unknown. Callers should expect a JSON object with liquidity-related metrics for TWT but will need to experiment to discover the exact shape. The endpoint accepts POST requests and is discoverable per its outputSchema metadata.

Quality
The endpoint is live (402 challenge confirmed) with clear pricing ($0.02/request in USDC on Base), but there is no OpenAPI schema, no documentation of request parameters or response fields, and no example payloads. The docs/pricing/README pages are all blank beyond a wallet connect prompt, making this effectively a stub listing.
