Look up the first transaction for any Tron wallet address via x402 micropayment.
What it does
This endpoint, hosted by Erudite Intelligence LLC on their EruditePay x402 Bridge, returns the first transaction associated with a given Tron wallet or contract address. It is a paid x402 endpoint that accepts a POST request with a JSON body containing an `address` field and returns JSON data about the wallet's earliest on-chain activity.
The endpoint accepts payment via two options: USDC on Base (eip155:8453) at $0.05 per call, or USDT on Tron (tron:728126428) at $0.05 per call. Both amounts are 50,000 base units with 6 decimals. Payment is facilitated through the x402 v2 protocol, with Coinbase CDP as one facilitator option. The provider describes the broader service as "Tron intelligence."
Documentation beyond the x402 challenge and the landing page is sparse — the `/docs` path returns a 404, and the Bazaar schema extension provides only a minimal example (an address field in the request body and a generic `{"success": true, "data": {}}` response). The exact structure of the returned transaction data is not documented. The endpoint is live and responds with a proper 402 challenge on POST requests.

Quality
The endpoint is live with a valid x402 challenge and a basic Bazaar schema, but documentation is effectively absent — /docs returns 404, the response example is a stub with an empty data object, and the actual fields returned are unknown. Pricing and payment options are clear from the challenge.
Warnings
- —No documentation available: /docs returns 404
- —Response schema is a stub — the example output is {"success": true, "data": {}} with no field definitions
- —The exact structure of returned transaction data is undocumented and must be discovered empirically
- —Provider description says only 'Tron intelligence' — no detailed endpoint-level docs exist
