Whale wallet intelligence for any address and chain, paid per-call via x402 (USDC on Base or USDT on Tron).
What it does
This endpoint from Erudite Intelligence LLC provides crypto data intelligence focused on whale wallets. You POST a wallet or contract address along with a chain identifier, and receive structured JSON data about that address. The endpoint is gated behind the x402 payment protocol (v2), meaning callers must attach a valid payment header to each request.
Pricing is 10,000 base units per call. On Base (eip155:8453) that's 10,000 / 10^6 = $0.01 in USDC; on Tron it's 10,000 / 10^6 = $0.01 in USDT. Payment is facilitated through the EruditePay Bridge, which supports Coinbase CDP verification on Base and direct Tron settlement. The facilitator charges a separate 0.5% settlement fee on top.
The response schema is minimal in the probe data — the example output is `{"success": true, "data": {}}` — so the exact fields returned for a real whale wallet lookup are not documented in the available material. The endpoint accepts POST requests with a JSON body containing `address` (wallet or contract address) and `chain` (blockchain network name). No OpenAPI spec or detailed documentation page was found; the docs URL returns a 404. Use this endpoint when you need on-demand whale wallet data and can pay per-call in stablecoin.

Quality
The endpoint is live (402 challenge captured) with a clear payment scheme and input schema, but the output schema is essentially empty (example data is {}), no OpenAPI spec exists, and the docs URL returns 404. The actual data returned for a real call is unknown.
Warnings
- —Output schema is a stub — the example response data field is an empty object, so actual response structure is unknown.
- —No OpenAPI specification or detailed documentation available (docs URL returns 404).
- —Exact fields and depth of whale wallet intelligence cannot be verified from available material.
