Retrieve top NFT collections on Base via x402 micropayment
What it does
This x402-enabled endpoint returns data about top NFT collections on the Base blockchain. Operated by Erudite Intelligence LLC, it accepts a POST request with an optional collection address or slug and returns JSON intelligence about NFT collections. The endpoint is live and returns a standard x402 payment challenge.
Payment is required per call: 10,000 base units of USDC on Base (eip155:8453) or 10,000 base units of USDT on Tron (tron:728126428). Since both USDC and USDT use 6 decimals, this equates to $0.01 (one cent) per request. The x402 facilitator is Coinbase CDP for the Base payment option. Settlement is handled through the EruditePay Bridge, which supports 20 blockchains and charges 0.5% per settlement.
Documentation is sparse — the endpoint description is simply "Crypto data intelligence" and the example output is a generic `{"success": true, "data": {}}` stub. The input schema accepts a `collection` field (string: NFT collection address or slug) in a JSON POST body, but the exact response structure for top collections data is not documented. No dedicated docs page exists (the /docs path returns a 404). Users should expect NFT collection ranking or analytics data for the Base chain, but the precise fields returned are unknown without making a paid call.
