Pay-per-call stock data API for ticker ABT, settled in USDC on Base via x402.
What it does
This endpoint at lowpaymentfee.com provides stock data for the ticker ABT (Abbott Laboratories) via a simple POST request, paid per call using the x402 protocol. Each request costs $0.02 in USDC on the Base network — no API keys, no rate limits, and no subscriptions required. The payment is settled on-chain to a specified wallet address.
The provider, lowpaymentfee.com, hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance/crypto market data, and utility services, all priced uniformly at $0.02 per request. This specific endpoint sits under the /api/v1/stocks/ path and is parameterized by ticker symbol (ABT in this case). The x402 challenge confirms the endpoint is live and accepts USDC (contract 0x8335…2913) on Base with a maximum amount of 20,000 base units (i.e., $0.02 given USDC's 6 decimals).
Documentation is extremely sparse — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI schema, no example request/response payloads, and no description of the response format beyond the stated mimeType of application/json. The endpoint is confirmed live via the 402 challenge, but the actual data quality, coverage, and response structure remain unknown.
