It is part of the lowpaymentfee.com platform, which offers a broad suite of data, analytics, AI, finance, and utility APIs — all gated behind the x402 payment protocol on the Base network.\n\nThe endpoint accepts POST requests and returns JSON. Each call costs $0.02 in USDC (the x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC on Base, which has 6 decimals = $0.02). No API keys or accounts are required; payment is handled inline via the X-PAYMENT header using the x402 exact-amount scheme. The payment settles to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 on the Base L2 network.\n\nDocumentation beyond the landing page is extremely sparse — the /docs, /api, /pricing, and /README pages all render only a \"Connect wallet\" prompt with no additional technical detail. There is no OpenAPI spec, no request/response schema, and no example payloads available. The specific request parameters (e.g., time range, interval/granularity) and response shape for the OHLCV data are unknown and must be discovered experimentally. The endpoint is confirmed live (returns a proper 402 challenge).","tags":[],"capabilities":["ohlcv-candlestick-data","crypto-market-data","bal-token","x402-payment","base-network","usdc-settlement","pay-per-request","no-api-key"],"categories":["finance","crypto"],"synonyms":["BAL OHLCV","Balancer candlestick","BAL price history","crypto candlestick API","BAL market data","OHLCV API","Balancer token chart data"],"warnings":["No API documentation available — /docs, /pricing, /api, and /README pages all return only a wallet-connect prompt with no technical content.","No OpenAPI or JSON schema for request or response; request parameters (interval, time range, etc.) are unknown.","No example responses available; the actual data format must be discovered by making a paid request.","The broader lowpaymentfee.com platform lists many endpoints across diverse categories (AI, analytics, finance, utilities) all at $0.02 — the depth and quality of each is unverified."],"endpointUrl":"https://lowpaymentfee.com/api/v1/crypto/BAL/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/BAL/ohlcv","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live and returns a valid x402 402 challenge, confirming it exists and is gated at $0.02/request in USDC on Base.
