NFT collection floor-price endpoint, pay-per-call at $0.02 via x402 on Base.
What it does
This x402-enabled endpoint at lowpaymentfee.com returns floor-price data for NFT collections. The specific route `/api/v1/collections/1/floor` serves collection #1's floor price. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) at a maximum cost of $0.02 per request (20,000 base units with 6 decimals). The endpoint accepts POST requests and returns JSON.
The broader lowpaymentfee.com platform advertises a wide catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and utility services — all priced at $0.02 per request. No API keys or rate limits are required; access is instant via the x402 payment protocol. However, the crawled documentation pages (docs, pricing, README) returned only a wallet-connect prompt with no substantive content, so details about request parameters, response schemas, and the actual data sources behind this endpoint are unknown.
Because the endpoint is live (returning a proper 402 challenge) but documentation is essentially absent, consumers should expect to experiment with the POST body to discover accepted parameters. The collection ID "1" in the URL path suggests a path-parameterized design where other collection IDs may also be queryable.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no documentation, no request/response schema, and no examples. The actual data source and accuracy of floor-price data are unknown.
Warnings
- —No documentation available — docs, pricing, and README pages all return only a wallet-connect prompt with no content.
- —No request body schema or response schema documented; consumers must discover parameters experimentally.
- —The specific data source for NFT floor prices is unknown; data quality and freshness cannot be verified.
- —The endpoint path references collection ID '1' but it is unclear what collection this maps to or what other IDs are valid.
