Pay-per-call OHLCV candlestick data for Filecoin (FIL) via x402 on Base.
What it does
This endpoint provides OHLCV (Open-High-Low-Close-Volume) candlestick data for the Filecoin (FIL) cryptocurrency. It is part of the lowpaymentfee.com platform, which offers a suite of data, AI, finance, and utility APIs all priced at $0.02 per request and settled via the x402 protocol on the Base network using USDC.
The endpoint accepts POST requests and returns JSON. Payment is handled inline via the X-PAYMENT header — no API keys, accounts, or rate limits are required. The x402 challenge confirms the endpoint is live, accepting up to 20,000 base units of USDC (i.e., $0.02) per call, paid to address 0x1A2B…85F3 on Base. The asset contract (0x8335…2913) is the canonical Base USDC contract.
Documentation beyond the landing page is extremely thin — the /docs, /api, /pricing, and /README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema, and no example payloads available. The exact query parameters (e.g., time range, interval) and response shape must be discovered experimentally. Because of this, the listing carries significant uncertainty about the precise capabilities and data quality of the endpoint.

Quality
The x402 challenge is live and confirms pricing and payment details, but there is no OpenAPI spec, no request/response schema, no documentation content (all doc pages show only 'Connect wallet'), and no example payloads. The endpoint's exact parameters and response format are unknown, making this effectively a stub listing.
Warnings
- —No API documentation available — /docs, /api, /pricing, and /README pages all render only 'Connect wallet' with no content.
- —No OpenAPI or JSON schema provided; request parameters and response shape are entirely unknown.
- —No example requests or responses available; integration requires trial-and-error discovery.
- —The broader lowpaymentfee.com platform lists many diverse endpoints (AI, analytics, finance, utilities) all at $0.02 — data quality and reliability are unverified.
