It is part of the lowpaymentfee.com platform, which offers a broad suite of data, analytics, AI, finance, and utility APIs — all payable per-request via the x402 protocol on the Base network using USDC.\n\nThe endpoint is live and returns a standard x402 402 challenge when called without payment. Each request costs $0.02 (20,000 base units of USDC, which has 6 decimals). Payment is made via the x402 \"exact\" scheme to a specified wallet address on Base. The endpoint accepts POST requests and returns JSON.\n\nThe provider's landing page lists uniform $0.02/request pricing across all endpoints, with no API keys, no rate limits, and no minimum commitments. However, documentation beyond the landing page is essentially empty (all doc/pricing/README pages just show a \"Connect wallet\" prompt), so the exact request body schema, supported query parameters (e.g., time range, interval), and response format for this OHLCV endpoint are not documented. Users should expect standard OHLCV fields but will need to experiment or contact the provider for specifics.","tags":[],"capabilities":["ohlcv-data","crypto-market-data","theta-token","x402-payment","per-request-pricing","base-network","usdc-settlement","json-response"],"categories":["finance","crypto"],"synonyms":["THETA candlestick data","THETA price history","THETA OHLCV","crypto OHLCV API","THETA market data","cryptocurrency candles","THETA trading data"],"warnings":["No documentation available for request body schema or response format — all doc pages show only 'Connect wallet'","No OpenAPI or machine-readable schema provided","Response structure and supported parameters (timeframe, interval, etc.) are unknown","The provider hosts many diverse endpoints under one domain; quality and reliability of each is unverified"],"endpointUrl":"https://lowpaymentfee.com/api/v1/crypto/THETA/ohlcv","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://lowpaymentfee.com/api/v1/crypto/THETA/ohlcv","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.400","qualityRationale":"The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02/request in USDC on Base).
