NFT collection statistics on Base via x402 micropayment (USDC/USDT)
What it does
This x402-enabled endpoint returns NFT collection statistics for collections on the Base blockchain. Operated by Erudite Intelligence LLC, it accepts a POST request with a JSON body containing a `collection` field (an NFT collection address or slug) and returns collection-level stats in JSON format.
The endpoint is live and returns a standard x402 v2 payment challenge. It accepts two payment methods: USDC on Base (eip155:8453) at 10,000 base units ($0.01 per call) and USDT on Tron (tron:728126428) at 10,000 base units ($0.01 per call). Payment is facilitated through the EruditePay x402 Bridge, which supports 20 blockchains and uses Coinbase CDP as one of its facilitators.
Documentation is sparse — the endpoint description in the challenge is simply "Crypto data intelligence" and the output example is a generic `{"success": true, "data": {}}` stub. There is no detailed documentation for this specific data endpoint (the provider's /docs path returns a 404). The exact fields returned in the `data` object for collection stats are not documented, so consumers should expect to discover the response shape empirically.

Quality
The endpoint is live (402 challenge captured) with a clear schema for input, but the output is a generic stub with no documented fields. No dedicated docs exist for this data endpoint. Pricing is clear ($0.01/call). The sparse output example and missing documentation significantly limit usability.
Warnings
- —Output schema is a generic stub — actual response fields for collection stats are undocumented
- —Provider docs path (/docs) returns 404; no detailed API documentation available
- —The example output {"success": true, "data": {}} may not reflect real response structure
