Compare TVL across multiple DeFi protocols via a pay-per-call x402 endpoint.
What it does
The `/v1/multi/tvl-compare` endpoint on EruditePay's Bridge provides crypto data intelligence, specifically Total Value Locked (TVL) comparison across multiple protocols or chains. It is an x402-gated POST endpoint that accepts a JSON body with a `query` parameter and returns structured JSON results.
Payment is required per call at $0.01 (10,000 base units of USDC on Base, or 10,000 base units of USDT on Tron). The endpoint supports two payment rails: USDC on Base (eip155:8453) via the Coinbase CDP facilitator, and USDT on Tron (tron:728126428). The provider is Erudite Intelligence LLC, a FinCEN-registered MSB.
Documentation is sparse — the endpoint description in the x402 challenge is simply "Crypto data intelligence," and the Bazaar schema shows a generic `query` string input with a generic `{success: true, data: {}}` output example. There is no dedicated API documentation page (the `/docs` path returns a 404). The exact query syntax, supported protocols, and response data structure are not documented in the available materials, so callers will need to experiment or contact the provider for details.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.01 per call), but documentation is essentially absent. The query syntax, supported protocols, and response schema are all undocumented — the Bazaar schema uses placeholder examples only. No dedicated docs page exists.
Warnings
- —No API documentation available — /docs returns 404
- —Query syntax and supported protocols/chains are undocumented
- —Output schema is a generic placeholder ({success: true, data: {}}) with no real field definitions
- —Endpoint description is vague: 'Crypto data intelligence'
