Monitor whale moves on Base and other blockchains via x402-paid crypto intelligence endpoint.
What it does
The whale-moves endpoint at bridge.eruditepay.com provides crypto data intelligence focused on monitoring large-value ("whale") transactions on blockchain networks. It is an x402-protocol endpoint operated by Erudite Intelligence LLC. Callers send a POST request with a JSON body specifying the blockchain network to monitor (e.g., `{"chain": "base"}`), and receive a JSON response containing whale movement data.
Payment is required per-call via the x402 protocol. The endpoint accepts two payment options: USDC on Base (network eip155:8453) at 10,000 base units ($0.01 USD) per request, or USDT on Tron (network tron:728126428) at 10,000 base units ($0.01 USD) per request. Payment is facilitated through the Coinbase CDP x402 facilitator for the Base option. The maximum payment timeout is 300 seconds for both options.
Documentation for this specific endpoint is sparse. The provider's landing page describes EruditePay Bridge primarily as an x402 payment facilitator supporting 20 blockchains, but the whale-moves endpoint appears to be a separate data intelligence product hosted on the same infrastructure. The response schema is only loosely defined — the example output shows `{"success": true, "data": {}}` with no further detail on what fields the `data` object contains. No dedicated docs page was found (the /docs path returns a 404). The endpoint is live and returning a valid x402 402 challenge.

Quality
The endpoint is live and returns a valid x402 402 challenge with pricing and schema metadata. However, documentation is essentially absent — no dedicated docs page exists, the output schema example is an empty object, and there is no description of what whale-moves data actually contains. The endpoint's purpose is inferred from its URL path and the brief 'Crypto data intelligence' description in the challenge.
Warnings
- —No dedicated documentation found for the whale-moves endpoint; /docs returns 404.
- —The example output schema shows an empty data object — actual response structure is unknown.
- —The provider's main site describes a payment facilitator, not a data intelligence product; this endpoint's capabilities are unclear.
- —Input schema only documents a 'chain' parameter; there may be additional undocumented parameters.
