Look up stablecoin transfer details by token address and transaction hash via x402 micropayment.
What it does
This x402-gated endpoint at bridge.eruditepay.com accepts a POST request containing a token contract address and a transaction hash, and returns data about the corresponding stablecoin transfer. The endpoint is described as "Crypto data intelligence" in its x402 challenge. Payment is required per-call: $0.01 in USDC on Base (eip155:8453) or $0.01 in USDT on Tron (tron:728126428), settled through the x402 protocol v2.
The request body takes two fields: `token` (a token address or symbol) and `hash` (a transaction hash). The response is a JSON object with a `success` boolean and a `data` object whose internal structure is not documented beyond the example stub `{}`. The endpoint is operated by Erudite Intelligence LLC, a FinCEN-registered MSB (BSA ID 31000324258137). The facilitator used for payment verification and settlement is Coinbase CDP's x402 endpoint.
Note that the provider's documentation link (docs.eruditepay.com) was not reachable during crawl, and the response schema's `data` field is unspecified, so the exact fields returned for a successful lookup are unknown. The endpoint is live and returning a valid x402 v2 challenge.

Quality
The endpoint is live with a valid x402 v2 challenge and a basic input schema, but the output schema's data field is an empty stub, the docs link returns nothing, and there is no documentation describing what fields are actually returned. Pricing and payment options are clear.
Warnings
- —The response data field is unspecified — the example is just an empty object, so actual return fields are unknown.
- —docs.eruditepay.com was referenced but not reachable; /docs on the bridge domain returns endpoint_not_found.
- —The endpoint description 'Crypto data intelligence' is vague and may not fully describe the functionality.
