Get the current FIL (Filecoin) token price via x402 micropayment on Base for $0.02 per request.
What it does
This endpoint returns the current price of the FIL (Filecoin) token. It is part of a broader suite of pay-per-call APIs hosted at lowpaymentfee.com, all accessible via the x402 payment protocol on the Base network. Each request costs $0.02 in USDC, with no API keys, rate limits, or subscriptions required — you simply attach an x402 payment header to your POST request.
The provider offers a range of endpoints spanning data analytics, AI/ML inference, finance/Web3 market data, and infrastructure utilities, all at the same $0.02 per-call price point. This specific endpoint sits in the Finance & Web3 category and is designed for retrieving real-time token pricing for Filecoin (FIL). The response MIME type is application/json.
The x402 challenge is live and well-formed: it advertises payment to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on Base, with a maxAmountRequired of 20000 base units (i.e., $0.02 given USDC's 6 decimals). The timeout is 300 seconds. No OpenAPI schema or detailed response documentation was found beyond the challenge's outputSchema stub, so the exact response shape must be inferred from the endpoint name and category.
Capabilities
Use cases
- —Fetching the current Filecoin (FIL) price for portfolio trackers or dashboards
- —Integrating real-time FIL pricing into trading bots or DeFi applications
- —Agent-driven price checks where no API key management is desired
- —On-demand token price queries with per-call USDC micropayments
Fit
Best for
- —AI agents or bots that need keyless, pay-per-call crypto price data
- —Developers prototyping apps that need FIL price without subscription overhead
- —Low-volume or sporadic price lookups where flat per-request pricing is economical
Not for
- —High-frequency trading requiring sub-second latency and bulk pricing (no documented bulk discount or websocket support)
- —Users who need historical price data or OHLCV candles (endpoint appears to return current price only)
- —Applications that cannot settle payments in USDC on Base

Quality
The x402 challenge is live and well-formed with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no response documentation, no example responses, and the crawled docs/pricing/README pages are all empty beyond a 'Connect wallet' stub. The response JSON example above is entirely inferred from the endpoint path and category.
Warnings
- —No OpenAPI or response schema available — the exact response format is unknown and the example_response_json is speculative.
- —Documentation pages (/docs, /pricing, /README) returned no meaningful content beyond 'Connect wallet'.
- —The broader provider site lists many endpoints but provides no detailed documentation for any of them.
- —The specific endpoint path mentions 'FIL' but no confirmation of what data fields are returned.
