What it does

This endpoint returns the current price of the THETA token. It is part of a broader suite of pay-per-call APIs hosted at lowpaymentfee.com, all settled via the x402 protocol on the Base network using USDC. The specific endpoint at `/api/v1/tokens/THETA/price` accepts POST requests and returns JSON.

Pricing is $0.02 per request (20,000 base units of USDC with 6 decimals). There are no API keys, no rate limits, and no subscription commitments — each call is paid individually via an x402 payment header. The payment is sent to the on-chain address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` using the USDC contract at `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` on Base.

The provider site lists many other endpoints across data/analytics, AI/ML, finance/Web3, and infrastructure categories, all at the same $0.02 price point. Documentation beyond the landing page is sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional technical detail. The exact response schema for this token price endpoint is not documented, so the output format must be inferred from the endpoint name and MIME type (application/json).

Quality

0.40/ 1.00

The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no documented response format, and all doc/pricing/README pages return only a wallet-connect prompt with no technical content. The example response is entirely inferred.

Warnings

  • —No API documentation available — docs, pricing, and README pages all show only 'Connect wallet' with no technical detail.
  • —Response schema is unknown; the example_response_json is speculative based on the endpoint path.
  • —No information on data source, update frequency, or accuracy of the THETA price feed.
