Real-time PERP token price data via x402 micropayment on Base for $0.02/request.
What it does
This endpoint returns the current price of the PERP token, accessible via the x402 payment protocol on the Base network. It is part of a broader suite of pay-per-request APIs offered by lowpaymentfee.com, covering data analytics, AI/ML inference, finance/Web3 data, and utility services. Each call costs $0.02 (20,000 base units of USDC on Base), with no API keys, rate limits, or subscriptions required.
The endpoint accepts POST requests and settles payment in USDC (contract 0x8335…2913) on the Base L2 network. The x402 challenge confirms the endpoint is live, advertising x402Version 1 with an "exact" payment scheme. The payment address is 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3, and the maximum timeout is 300 seconds. The response MIME type is application/json.
Documentation on the site is extremely sparse — 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 documentation, and no usage examples available. The exact shape of the JSON response (e.g., whether it includes timestamp, source, or historical data) is unknown and must be inferred from the endpoint path alone.
Capabilities
Use cases
- —Fetching the current PERP token price for trading bots or portfolio dashboards
- —Integrating real-time PERP pricing into DeFi applications without managing API keys
- —Agent-driven price checks where per-call micropayments replace subscription billing
Fit
Best for
- —Developers needing on-demand PERP token pricing without subscription overhead
- —AI agents that can autonomously pay per request via x402
- —Low-volume or bursty use cases where flat-rate plans are wasteful
Not for
- —High-frequency trading requiring sub-second latency and bulk pricing tiers
- —Users who need historical OHLCV candle data or charting (no evidence this endpoint provides it)
- —Anyone without a Base-network USDC wallet to settle x402 payments

Quality
The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no request/response schema, and all documentation pages are empty beyond a wallet-connect prompt. The endpoint's actual response format is entirely unknown.
Warnings
- —No OpenAPI or schema documentation available — request body and response shape are unknown.
- —Docs, API, pricing, and README pages all render only 'Connect wallet' with no usable content.
- —No examples or sample responses are provided anywhere on the site.
- —The broader site lists many endpoints but it is unclear whether all are functional or placeholders.
