Cross-chain wallet combined value lookup via x402 micropayment
What it does
This endpoint, operated by Erudite Intelligence LLC, accepts a wallet or contract address and returns aggregated cross-chain value data. It is an x402-gated POST endpoint described as "Crypto data intelligence" in its payment challenge. The endpoint accepts a JSON body with an `address` field (a wallet or contract address) and returns a JSON object with a `success` boolean and a `data` object.
The endpoint accepts payment via two channels: USDC on Base (eip155:8453) or USDT on Tron (tron:728126428), each priced at 10,000 base units — which equals $0.01 per request (both USDC and USDT use 6 decimals). Payment is facilitated through the EruditePay x402 Bridge, which supports 20 blockchains and implements x402 v2. The facilitator on Base uses the Coinbase CDP x402 infrastructure.
Documentation is sparse: the endpoint's behavior is inferred primarily from the x402 challenge metadata and the Bazaar schema extension. The example output (`{"success": true, "data": {}}`) suggests the response `data` object contains wallet value information, but the exact fields are not documented. The provider's landing page focuses on the Bridge facilitator service itself rather than this specific data endpoint, and dedicated docs at /docs return a 404.
Capabilities
Use cases
- —Querying the total combined value held by a wallet address across multiple blockchains
- —Building portfolio dashboards that need a single aggregated value for any address
- —Agent-driven crypto intelligence workflows that need on-demand wallet valuation
- —Risk scoring or due diligence checks on wallet addresses before transactions
Fit
Best for
- —AI agents needing per-call crypto wallet intelligence without API key management
- —Cross-chain wallet value lookups at $0.01 per request
- —Programmatic portfolio valuation across multiple blockchains
Not for
- —High-frequency bulk wallet scanning (per-call cost adds up)
- —Detailed per-token or per-chain balance breakdowns (response schema is undocumented)
- —Historical wallet value or time-series analytics (no evidence of historical support)

}Response

"data": {},
"success": true
}Endpoint
Quality
The endpoint is live (402 challenge captured) with a valid Bazaar schema extension, but documentation is extremely thin. The response data structure is unknown beyond the stub example, and no dedicated docs page exists. Pricing is clear at $0.01/call.
Warnings
- —Response data schema is undocumented — the example output shows an empty data object
- —No dedicated API documentation available (docs.eruditepay.com referenced but /docs returns 404)
- —Exact fields returned in the data object are unknown; consumers should test with a real payment to discover the schema
