Token holder concentration data for Base chain tokens, paid per-call via x402 in USDC or USDT.
What it does
This endpoint provides crypto token holder concentration intelligence for tokens on the Base network (and potentially other chains). You POST a token address and receive concentration data about that token's holder distribution. The endpoint is operated by Erudite Intelligence LLC and is gated behind the x402 payment protocol (version 2).
Pricing is $0.01 per call, payable in either USDC on Base (eip155:8453) or USDT on Tron (tron:728126428). The x402 challenge advertises an amount of 10,000 base units; since both USDC and USDT use 6 decimals, this equals $0.01 per request. Payment is facilitated through the EruditePay Bridge, which settles via Coinbase CDP for Base and natively for Tron.
Documentation is sparse — the endpoint's schema shows a simple JSON body with a single `token` field (a token address or symbol), and the example output is a generic `{"success": true, "data": {}}` stub. The exact structure of the concentration data returned is not documented. The provider's landing page describes EruditePay as an x402 payment facilitator supporting 20 blockchains, but specific documentation for this data intelligence endpoint is not available (the /docs path returns a 404).

Quality
The endpoint is live (returns a valid x402 v2 challenge with clear pricing), but documentation is extremely thin. The output schema example is an empty stub, so the actual response structure is unknown. No dedicated docs page exists. Pricing and payment details are clear from the challenge.
Warnings
- —Output data structure is undocumented — the example response contains an empty data object
- —No dedicated API documentation available (/docs returns 404)
- —The exact meaning of 'concentration' metrics (e.g., Gini coefficient, top-N holders, HHI) is not specified
- —Only a single example token address (zero address) is provided in the schema, unclear what tokens/chains are supported
