Pay-per-call stock quote API for ADBE via x402 on Base, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides stock data for Adobe (ADBE) through a pay-per-call x402 protocol. The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) at a cost of $0.02 per request (20,000 base units with 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.
The provider hosts a broader suite of APIs spanning data analytics, AI/ML inference (sentiment, summarization, classification, embeddings), finance (price feeds, exchange rates, crypto quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation), all priced uniformly at $0.02 per request. However, this specific listing covers only the `/api/v1/stocks/ADBE` endpoint.
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 MIME type `application/json`. The endpoint is confirmed live via a 402 challenge response.
