Exchange net-flow crypto data intelligence via x402 micropayment on Base and Tron
What it does
This endpoint at bridge.eruditepay.com provides crypto data intelligence focused on exchange net-flow data. It is an x402-gated POST endpoint operated by Erudite Intelligence LLC. Callers send a JSON body with a `query` parameter and receive structured JSON results. Payment is required per-call via the x402 protocol (version 2), accepting USDC on Base (eip155:8453) or USDT on Tron (tron:728126428) at $0.01 per request (10,000 base units with 6 decimals).
The endpoint is live and returns a proper 402 challenge. However, documentation is extremely sparse — the crawled docs, API, pricing, and README paths all return 404. The bazaar schema in the x402 challenge describes a generic input/output contract: POST a JSON body with a `query` string and receive `{"success": true, "data": {}}`. No further detail on what queries are supported, what exchange net-flow metrics are available, or what the `data` object contains is provided anywhere in the crawled material.
The facilitator for Base payments is Coinbase CDP (api.cdp.coinbase.com). The provider is registered as a FinCEN MSB (BSA ID 31000324258137) and operates a non-custodial settlement model. The bridge itself supports 20 blockchains for settlement, though this specific data endpoint only accepts payment on Base and Tron.

Quality
The endpoint is live and returns a valid x402 challenge, but documentation is effectively nonexistent — all doc paths return 404. The bazaar schema is generic (a single 'query' string input, an empty 'data' object output) with no specifics on supported queries, available exchanges, time ranges, or response fields. Pricing is clear ($0.01/call) but the actual data contract is opaque.
Warnings
- —No documentation available — /docs, /api, /pricing, /README all return 404
- —The bazaar schema is generic placeholder-level: input is just {"query": "string"} and output example is {"data": {}}
- —Exact query syntax, supported exchanges, and response data structure are unknown
- —Cannot verify what data is actually returned without making a paid request
