US W-2 tax data for 2024 via per-request x402 micropayment on Base (USDC).
What it does
This endpoint at lowpaymentfee.com provides access to 2024 W-2 tax-related data through a simple POST request, paid per call using the x402 protocol. Payment is settled in USDC on the Base network at $0.02 per request (20,000 base units of USDC with 6 decimals). No API keys, rate limits, or upfront commitments are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers dozens of x402-gated APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services, all priced uniformly at $0.02 per request. The specific endpoint `/api/v1/tax/w2/2024` is not documented in detail on the site's landing page (which lists other categories but not tax endpoints), so the exact input schema and response format are unknown. The x402 challenge confirms the endpoint is live, accepts POST requests, and returns application/json.
Because the provider's documentation pages (docs, pricing, README) all resolve to a minimal "Connect wallet" stub with no further detail, the precise fields accepted and returned by this tax endpoint remain unclear. Callers should expect to experiment or contact the provider for schema details.

Quality
The x402 challenge confirms the endpoint is live and priced at $0.02 USDC on Base, but there is no documentation for the tax/w2/2024 endpoint — no input schema, no response examples, and the docs pages are empty stubs. The endpoint is not even listed on the provider's own landing page, making it effectively a stub listing.
