Look up early buyers of any token on Base via x402-paid crypto intelligence endpoint.
What it does
This x402-gated endpoint from Erudite Intelligence LLC returns early-buyer data for a given token. You POST a JSON body containing a token address (or symbol), and the endpoint responds with intelligence about the earliest buyers of that token. The service is described as "Crypto data intelligence" in the x402 challenge.
Payment is required per-call via the x402 protocol (v2). The endpoint accepts two payment options: USDC on Base (eip155:8453) at 0.01 USDC per request, or USDT on Tron (tron:728126428) at 0.01 USDT per request. Settlement is facilitated through the EruditePay Bridge, which supports 20 blockchains and charges 0.5% per settlement. The facilitator is Coinbase CDP's x402 endpoint.
Documentation is sparse — the endpoint's output schema only provides a generic example (`{"success": true, "data": {}}`) without detailing the structure of the returned early-buyer data. The provider's landing page focuses on the EruditePay Bridge facilitator service rather than this specific data endpoint. No dedicated API docs were found for the token intelligence endpoints. The input schema is straightforward: a POST with a JSON body containing a `token` field (token address or symbol).

Quality
The endpoint is live (402 challenge captured) with a clear input schema and pricing, but the output schema is essentially a stub with an empty data object. No dedicated documentation exists for this endpoint, and the response structure must be inferred. The provider's site documents the facilitator bridge, not the data endpoints.
Warnings
- —Output schema is a stub — the example response shows only {"success": true, "data": {}} with no detail on what early-buyer data fields are returned.
- —No dedicated API documentation found for this endpoint; /docs returns 404.
- —The exact structure and completeness of early-buyer data is unknown — callers should test with a small payment first.
