Real-time stock price data for LMND via x402 micropayment on Base network.
What it does
This x402 endpoint at lowpaymentfee.com provides real-time stock price data for the ticker LMND (Lemonade, Inc.). It is part of a broader platform offering pay-per-request APIs across finance, analytics, AI/ML, and infrastructure categories, all gated behind the x402 payment protocol on the Base network using USDC.
The specific endpoint `/api/v1/stock/price/LMND` accepts POST requests and returns JSON. Payment is made via the x402 `X-PAYMENT` header with a maximum cost of 20,000 units of USDC (on Base, contract `0x8335...2913`), which at 6 decimals equals $0.02 per request. The platform advertises no API keys, no rate limits, and instant access — you pay per call with no subscriptions or commitments.
Documentation 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 schema, no example request/response payloads, and no description of the response format. The endpoint is confirmed live (returns 402 challenge on POST), but the actual response schema for a paid request is unknown. The platform hosts many other endpoints (analytics, AI, crypto, finance, utilities) at similar price points, suggesting a broad but lightly documented API suite.

Quality
The endpoint is confirmed live with a valid 402 challenge and clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no documented request/response format, no example payloads, and the docs/pricing/README pages are all empty beyond a wallet-connect prompt. The listing is functional but severely under-documented.
Warnings
- —No OpenAPI or JSON schema available for request or response payloads

- —Response format for a successful paid request is completely unknown
