Get the current stock price for KO (Coca-Cola) via a pay-per-call x402 endpoint on Base.
What it does
This endpoint returns the current stock price for the ticker KO (Coca-Cola) through the lowpaymentfee.com platform, which offers a suite of pay-per-request APIs settled via the x402 protocol on the Base network using USDC. Each call costs $0.02 (20,000 base units of USDC with 6 decimals). No API keys or accounts are required — payment is handled inline via the X-PAYMENT header.
The endpoint accepts POST requests and returns JSON. It is part of a broader catalog on lowpaymentfee.com that includes data analytics, AI/ML inference, finance/crypto feeds, and utility endpoints, all priced at $0.02 per request. The x402 challenge was successfully captured, confirming the endpoint is live and accepting payment on Base (asset contract 0x8335…2913, which is USDC on Base).
Documentation beyond the landing page is sparse — the /docs, /pricing, /api, and /README pages all returned only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of the response schema. The endpoint path suggests it returns a price for the KO stock ticker, but the exact response format is unknown.

Quality
The endpoint is confirmed live via a valid 402 challenge, and pricing is clear ($0.02 per request in USDC on Base). However, there is no OpenAPI spec, no documented request/response schema, no example payloads, and all documentation pages are empty beyond a wallet-connect prompt. The actual response format must be guessed from the URL path alone.
Warnings
- —No OpenAPI or schema documentation available — response format is unknown
- —All doc/pricing/README pages return only a 'Connect wallet' prompt with no content
- —No example request or response payloads are provided anywhere
- —The exact data source for stock prices is not disclosed — accuracy and freshness are unverifiable
