What it does

This x402-gated endpoint from Erudite Intelligence LLC provides crypto data intelligence focused on whale transfers. You submit a POST request containing a transaction hash and a chain identifier (e.g. "base"), pay per call via the x402 protocol, and receive structured JSON data about the transfer.

The endpoint accepts payment in USDC on Base (EIP-155:8453) or USDT on Tron, at a cost of 10,000 base units per request — which equals $0.01 USD per call (both USDC and USDT use 6 decimals). Payment is facilitated through the EruditePay x402 Bridge, which supports 20 blockchains and settles via the Coinbase CDP facilitator or directly. The provider is a FinCEN MSB-registered entity (BSA ID 31000324258137).

Documentation is sparse: the endpoint's own description is simply "Crypto data intelligence," and the example output is a generic `{"success": true, "data": {}}` stub. There is no detailed schema for the response payload, so the exact fields returned for whale transfer lookups are unknown. The endpoint is live and returns a valid x402 v2 challenge on POST. The EruditePay Bridge landing page is operational (HTTP 200), but dedicated docs pages (/docs, /api) return 404.

Capabilities

Use cases

  • —Look up details of large whale transfers by transaction hash on Base or other supported chains
  • —Monitor whale activity programmatically by querying individual transactions
  • —Integrate whale transfer intelligence into trading bots or dashboards
  • —Enrich blockchain analytics pipelines with per-transaction whale data

Fit

Best for

  • —Agents or bots that need on-demand whale transfer lookups at $0.01/call
  • —Crypto analytics platforms wanting pay-per-query data without subscriptions
  • —Developers building x402-native applications on Base

Not for

  • —Bulk historical whale data exports (pay-per-call model would be expensive at scale)
  • —Non-crypto use cases — this endpoint is blockchain-specific
  • —Users who need detailed API documentation before integrating (docs are minimal)

Quality

0.45/ 1.00

The endpoint is live with a valid x402 v2 challenge and clear pricing ($0.01/call in USDC or USDT). However, documentation is essentially absent — the response schema is a stub with an empty data object, there are no dedicated docs pages, and the endpoint description is vague ("Crypto data intelligence"). The actual structure of whale transfer data returned is unknown.

Warnings

  • —Response schema is a stub — the example output is {"success": true, "data": {}} with no field definitions
  • —No dedicated documentation available (/docs, /api, /pricing all return 404)
  • —Exact fields and depth of whale transfer data are unverified
  • —Provider description is generic: 'Crypto data intelligence' — unclear what specific data points are returned
