It is an x402-gated POST endpoint hosted by Erudite Intelligence LLC at bridge.eruditepay.com. You send a JSON body with a `protocol` field (e.g. \"aave\") and receive structured TVL data in return.\n\nPayment is required per-call via the x402 protocol (version 2). The endpoint accepts two payment options: USDC on Base (EIP-155:8453) at 10,000 base units ($0.01) per request, or USDT on Tron at 10,000 base units ($0.01) per request. The Coinbase CDP facilitator is used for Base settlements. The endpoint returns JSON with a `success` boolean and a `data` object containing the TVL information.\n\nDocumentation is sparse — the provider's /docs path returns a 404, and the only schema information comes from the x402 challenge's embedded Bazaar extension. The input schema specifies a single `protocol` field described as \"DeFi protocol name or address.\" The output example shows `{\"success\": true, \"data\": {}}` but does not detail the structure of the data object. The provider, Erudite Intelligence LLC, is a FinCEN-registered MSB and operates the EruditePay x402 Bridge facilitator supporting 20 blockchains.","tags":[],"capabilities":["defi-tvl-query","x402-payment","usdc-base","usdt-tron","protocol-lookup","json-api","micropayment-gated"],"categories":["defi","crypto-data"],"synonyms":["total
