Monitor token activity on Base and other chains via x402-paid crypto data intelligence endpoint.
What it does
This x402-protected endpoint from Erudite Intelligence LLC provides crypto data intelligence by monitoring token activity on specified blockchain networks. You send a POST request with a token address (or symbol) and a chain identifier, and receive structured JSON data about that token's activity.
The endpoint accepts payment via two methods: USDC on Base (eip155:8453) or USDT on Tron (tron:728126428), both 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 uses the Coinbase CDP facilitator for Base settlements. The provider is a FinCEN MSB-registered entity (BSA ID 31000324258137) operating a non-custodial settlement model.
Documentation is sparse: the Bazaar schema embedded in the 402 challenge describes the input (token address and chain) and a minimal output example (`{"success": true, "data": {}}`), but there is no detailed API documentation available — the /docs path returns a 404. The exact structure and richness of the returned `data` object is unknown. The endpoint is live and returning a valid x402 v2 challenge.
Capabilities
Use cases
- —Monitoring transfer and trading activity for a specific token on Base or other supported chains
- —Building dashboards that track token movements in real time
- —Feeding token activity data into trading bots or alert systems
- —Enriching wallet or portfolio apps with token-level activity intelligence
Fit
Best for
- —Agents needing per-call token activity data without API key management
- —Developers building crypto monitoring tools who want pay-per-request pricing
- —Applications that need on-chain token activity data at very low cost ($0.01/call)
Not for
- —High-frequency bulk data ingestion where per-call pricing adds up quickly
- —Users who need detailed API documentation before integrating — docs are currently unavailable
- —Non-crypto use cases or fiat-only payment environments

Quality
The endpoint is live with a valid x402 v2 challenge and embedded Bazaar schema, but documentation is effectively absent (all doc paths return 404). The output example is a stub with an empty data object, so the actual response structure is unknown. Pricing and payment options are clear.
Warnings
- —No API documentation available — /docs returns 404
- —Output example in the Bazaar schema is a stub with an empty data object; actual response structure is unknown
- —The exact fields and depth of the 'data' object in the response cannot be verified from available material
- —Provider description says 'Crypto data intelligence' but specifics of what token-activity data is returned are not documented
