It is part of the EruditePay x402 Facilitator platform, which exposes 353 pay-per-call blockchain analytics endpoints across Base, Tron, Bitcoin, XRP, and Kaspa. The specific endpoint at `/api/tron/contract-events` accepts query parameters for contract address, event name, pagination (limit, fingerprint), and a since filter. Payment is $0.005 per call in USDC on Base (network eip155:8453) or USDT on Tron (network tron:0x2b6653dc).\n\nThe endpoint is live and returns a standard x402 402 Payment Required challenge when called without payment. The challenge confirms the price is 5000 base units of USDC (6 decimals), which equals $0.005 per call. The facilitator URL is https://bridge.eruditepay.com. The OpenAPI spec provides full parameter definitions but no response schema beyond a brief example showing `{success: true, data: {contractAddress, events: []}}`. No detailed documentation pages were found beyond the facilitator landing page.\n\nEruditePay is operated by Erudite Intelligence LLC, a FinCEN MSB-registered entity (BSA ID 31000324258137). The facilitator supports 20 blockchains and settles at 0.5% per settlement. Verification calls are free. The platform also offers 60-second bundle tokens for bulk access at reduced per-call rates.","tags":[],"capabilities":["tron-contract-events","smart-contract-event-decoding","tron-blockchain-analytics","x402-micropayment","pay-per-call","multi-chain-payment","pagination-support"],"categories":["blockchain","analytics"],"synonyms":["tron events","tron contract logs","TRC20 events","tron smart contract events","tron event listener","tron decoded events","eruditepay tron"],"warnings":["No detailed response schema available — only a brief example in the x402 challenge","Documentation pages (/docs, /api, /pricing) returned 404 at crawl time","The endpoint URL in the listing (x402.eruditepay.com) differs from the actual server URL (bridge.eruditepay.com) — the facilitator routes through bridge.eruditepay.com"],"endpointUrl":"https://x402.eruditepay.com/api/tron/contract-events","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x602e5935a047BE6Eac9b4393EeccD46350f4A3Ed","amount":"5000","scheme":"exact","network":"eip155:8453","maxTimeoutSeconds":300},{"asset":"TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t","extra":{"name":"TronTransferAuthorization","version":"1","wrapper":"THGkLBrLY1G5VovZjjK1jP9upyxRdMNL3b"},"payTo":"TSevuRZFjpckeMSSDhQFoiAkPCkckuE5TP","amount":"5000","scheme":"exact","network":"tron:728126428","maxTimeoutSeconds":300}]},"qualityScore":"0.750","qualityRationale":"Full OpenAPI schema with parameter definitions and clear x402 402 challenge captured, confirming the endpoint is live at $0.005/call.
