Retrieve crypto wallet portfolio data for any address on Base, paid per-call via x402.
What it does
This x402-gated endpoint, operated by Erudite Intelligence LLC, accepts a wallet or contract address and returns portfolio data described as "Crypto data intelligence." The endpoint lives at `https://bridge.eruditepay.com/v1/base/wallet/portfolio` and responds to POST requests with a JSON body containing an `address` field.
Pricing is $0.01 per call, payable in USDC on Base (eip155:8453) or USDT on Tron (tron:728126428). The x402 v2 challenge was captured live, confirming the endpoint is operational. Payment is facilitated through the EruditePay Bridge, which supports 20 blockchains and uses Coinbase CDP as one of its facilitators.
Documentation is sparse — the crawled site focuses on the EruditePay Bridge facilitator service rather than this specific data endpoint. The response schema shows `{"success": true, "data": {}}` as an example but does not detail the structure of the `data` object. The provider is a FinCEN-registered MSB (BSA ID 31000324258137) and operates non-custodially. Because the actual portfolio response payload is undocumented, callers should expect to discover the data shape empirically.

Fit
Best for

Quality
The endpoint is live (402 challenge captured) with a clear schema for the request body, but the response payload is undocumented beyond a stub example. No OpenAPI spec, no dedicated docs page, and the crawled site focuses on the facilitator bridge rather than this data endpoint.
Warnings
- —Response data structure is undocumented — the example shows an empty object
- —No OpenAPI or dedicated API documentation found for this endpoint
- —The /docs, /api, /pricing, and /README paths all return 404
- —Endpoint description is generic ('Crypto data intelligence') with no detail on what portfolio fields are returned
