What it does

This x402-enabled endpoint, hosted by Erudite Intelligence LLC at bridge.eruditepay.com, returns NFT valuation data for a given wallet address and NFT collection on the Base network. Callers POST a JSON body containing an `address` (wallet or contract address) and a `collection` (NFT collection address or slug), and receive a JSON response with valuation intelligence.

Payment is required per-call via the x402 protocol (v2). The endpoint accepts 0.01 USDC on Base (eip155:8453) or 0.01 USDT on Tron (tron:728126428). Settlement is facilitated through the EruditePay Bridge, which supports 20 blockchains and uses Coinbase CDP as one of its facilitators. The provider is described as offering "Crypto data intelligence."

Documentation is sparse — the crawled /docs path returns a 404, and the Bazaar schema embedded in the x402 challenge provides only a minimal example output (`{"success": true, "data": {}}`). The exact structure of the returned NFT valuation data is not documented beyond this stub. The endpoint is live and returns a well-formed 402 challenge on POST requests.

Quality

0.45/ 1.00

The endpoint is live and returns a valid x402 challenge with a Bazaar schema, but documentation is effectively absent (all doc paths 404). The output example is a stub with an empty data object, so the actual response structure is unknown. Pricing is clear ($0.01 per call).

Warnings

  • —No dedicated documentation available — /docs returns 404
  • —Output schema is a stub; the actual shape of the 'data' field is undocumented
  • —The example response from the Bazaar extension shows only {"success": true, "data": {}} with no real fields
  • —It is unclear what valuation methodology or data sources are used
