Pay-per-call stock price lookup for ABBV via x402 on Base (USDC).
What it does
This endpoint returns the current stock price for AbbVie (ticker ABBV) 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 — callers simply attach an X-PAYMENT header with a valid x402 payment proof.
The endpoint accepts POST requests and returns JSON. It is part of a broader catalog on lowpaymentfee.com that includes finance, analytics, AI/ML, crypto, and utility endpoints, all priced uniformly at $0.02 per request. The x402 challenge confirms the endpoint is live, discoverable, and accepting payments to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 on Base.
Note that the specific response schema for this stock price endpoint is not documented — the crawled docs pages returned only a wallet-connect prompt with no further detail. The exact fields returned (e.g., current price, timestamp, volume) must be inferred from the endpoint name and general finance API conventions. Use with caution if you need guaranteed field names.

Quality
The x402 challenge is live and confirms pricing, network, and asset. However, there is no OpenAPI schema, no documented request/response format, and the docs pages are empty (wallet-connect only). The endpoint's actual output fields are unknown.
Warnings
- —No response schema or example response is documented — field names and structure are unknown.
- —Documentation pages (/docs, /api, /pricing, /README) returned no useful content beyond a wallet-connect prompt.
- —The specific stock price endpoint (/api/v1/stocks/ABBV/price) is not listed on the homepage catalog, which lists /api/v1/finance/prices instead — it may be an unlisted or experimental route.
