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

0.40/ 1.00

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.
