Top smart-contract analytics on Base, paid per-call via x402 in USDC or USDT.
What it does
This endpoint from Erudite Intelligence LLC returns analytics about the most active or notable smart contracts on the Base blockchain (eip155:8453). It accepts a POST request with a JSON body containing a `query` parameter and returns structured JSON data. Payment is handled via the x402 protocol: each call costs 0.01 USDC on Base or 0.01 USDT on Tron, settled through the EruditePay Bridge facilitator.
The endpoint is live and returns a standard x402 v2 payment challenge (HTTP 402) to unauthenticated callers. The response schema indicates a JSON object with `success` (boolean) and `data` (object) fields, though the exact shape of the analytics payload within `data` is not documented beyond the placeholder example. The provider describes the service broadly as "Crypto data intelligence."
Documentation is sparse — the provider's /docs path returns a 404, and no OpenAPI spec is published. The input schema specifies a `query` string parameter in the POST body, but valid query values, filtering options, pagination, and the detailed structure of the returned analytics data are all undocumented. Pricing is clear: 10,000 base units of USDC (6 decimals) = $0.01 per call on Base, or the equivalent in USDT on Tron.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.01 per call). However, documentation is effectively absent: no OpenAPI spec, /docs returns 404, the output schema is a stub ({data: {}}), and valid query values are unknown. The listing is largely inferred from the x402 challenge and the provider's landing page.
Warnings
- —No documentation available — /docs returns 404 and no OpenAPI spec is published.
- —The output example is a stub: {"success": true, "data": {}}. The actual analytics payload structure is unknown.
- —Valid values for the 'query' parameter are undocumented; callers must guess or experiment.
- —Only the generic description 'Crypto data intelligence' is provided by the endpoint metadata.
