Query NFT ownership data via x402 micropayment on Base for $0.02 per request.
What it does
This endpoint at lowpaymentfee.com returns NFT ownership information for NFT ID 94. It is part of a broader platform offering pay-per-request APIs across data analytics, AI/ML inference, finance/Web3, and infrastructure categories — all settled via the x402 protocol on the Base network using USDC.
The specific endpoint `/api/v1/nfts/94/owner` accepts POST requests and returns JSON. Payment is handled inline via the X-PAYMENT header using the x402 exact-payment scheme. The maximum amount required is 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals). The payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on the Base network, with a timeout of 300 seconds.
The platform advertises no API keys, no rate limits, and instant access. All endpoints on the site are uniformly priced at $0.02 per request. No OpenAPI schema or detailed documentation was found beyond the landing page listing and the x402 challenge itself, so the exact request body format and response structure for this NFT owner endpoint are unknown.

Quality
The endpoint is live and returns a valid x402 402 challenge, confirming it is operational. However, there is no OpenAPI spec, no documentation of request/response schemas, and the endpoint is narrowly scoped to a single NFT ID. The crawl pages beyond the landing page returned only 'Connect wallet' with no useful content.
Warnings
- —No OpenAPI or schema documentation available — request body format and response structure are unknown.
- —Endpoint is scoped to a single NFT ID (94); unclear if other NFT IDs are available at similar paths.
- —Landing page lists many API categories but no detailed docs were accessible; actual functionality behind each endpoint is unverified.
- —No robots.txt or agents.txt found.
