Retrieve total cryptocurrency market capitalization via x402 micropayment on Base or Tron.
What it does
This endpoint returns total crypto market capitalization data, payable per-call via the x402 protocol. It accepts a POST request with a JSON body containing a `token` field (token address or symbol) and returns market-cap intelligence in JSON format. The endpoint is operated by Erudite Intelligence LLC.
Payment is required at $0.01 per call (10,000 base units of USDC on Base or USDT on Tron, both 6-decimal stablecoins). The x402 v2 challenge is live and well-formed, with two accepted payment options: USDC on Base (eip155:8453) settled via the Coinbase CDP facilitator, or USDT on Tron (tron:728126428). The maximum payment timeout is 300 seconds.
Documentation is sparse — the provider's landing page describes the EruditePay Bridge facilitator infrastructure but does not document the `/v1/market/total-mcap` data endpoint specifically. The example output in the Bazaar schema extension is a generic `{"success": true, "data": {}}` stub, so the exact shape of the returned market-cap data is unknown. No OpenAPI spec or dedicated docs page was found for this endpoint.

Quality
The x402 challenge is live and well-structured with clear pricing ($0.01/call), but there is no dedicated documentation for this endpoint, the example response is a generic stub with an empty data object, and no OpenAPI spec exists. The actual response schema and data semantics must be inferred.
