Query token transfer volume data on Base via x402-paid crypto intelligence endpoint.
What it does
This endpoint, hosted by Erudite Intelligence LLC on their EruditePay x402 Bridge, provides crypto data intelligence focused on token transfer volumes on the Base blockchain. Callers POST a JSON body containing a token address and a transaction hash, and receive structured transfer-volume data in return. The endpoint is gated behind the x402 payment protocol (v2), requiring per-call payment of $0.01 (10,000 base units of USDC on Base, or equivalently 10,000 base units of USDT on Tron).
The x402 challenge confirms the endpoint is live and accepts payments via two networks: Base (EIP-155:8453) using USDC at contract 0x8335…2913, and Tron (728126428) using USDT at contract TR7NHq…Lj6t. Settlement is facilitated through the Coinbase CDP x402 facilitator on Base and directly on Tron. The provider is a FinCEN-registered MSB (BSA ID 31000324258137) operating a non-custodial settlement model.
Documentation is sparse — the /docs, /api, and /README paths all return 404-style errors, and the Bazaar schema embedded in the x402 challenge provides only a minimal example output (`{"success": true, "data": {}}`). The exact shape of the returned transfer-volume data is not documented, so consumers should expect to discover the response structure empirically. The endpoint description in the challenge is simply "Crypto data intelligence," offering little detail about what metrics or aggregations are returned.
Capabilities
Use cases
- —Querying aggregate transfer volume for a specific token on Base
- —Investigating transfer activity associated with a particular transaction hash
- —Building dashboards or alerts around on-chain token movement on Base
- —Feeding token transfer volume data into trading or risk models
Fit
Best for
- —Agents or bots needing programmatic, pay-per-call access to Base token transfer data
- —Developers building crypto analytics tools who want x402-native payment integration
- —On-chain researchers analyzing token movement patterns on Base
Not for
- —Users needing historical multi-chain transfer data beyond Base (endpoint is Base-specific)
- —Anyone requiring detailed documentation or guaranteed response schemas before integration
- —Free-tier or high-volume bulk data consumers (each call costs $0.01)

}Endpoint
Quality
The endpoint is live (402 challenge captured) with a valid Bazaar schema, but documentation is effectively absent — /docs returns 404, the output example is an empty object, and the endpoint description is generic ('Crypto data intelligence'). The exact response structure and semantics of the returned data are unknown.
Warnings
- —No external documentation available — /docs, /api, /README all return errors
- —Response data shape is undocumented; the example output is just {"success": true, "data": {}}
- —Endpoint description is vague ('Crypto data intelligence') with no detail on what transfer-volume metrics are returned
- —No OpenAPI spec or detailed schema beyond the minimal Bazaar extension
