DEX price-impact analysis for tokens on Base, paid per call via x402 in USDC or USDT.
What it does
The `/v1/base/dex/price-impact` endpoint, operated by Erudite Intelligence LLC, returns price-impact data for tokens traded on Base-chain decentralized exchanges. You POST a JSON body containing a token address (or symbol), and the endpoint responds with price-impact intelligence. Payment is handled via the x402 protocol: each call costs 0.01 USDC on Base (EIP-155:8453) or 0.01 USDT on Tron, settled through the EruditePay Bridge facilitator.
The endpoint accepts POST requests with a JSON body containing a `token` field (a contract address or symbol string). The response is JSON with a `success` boolean and a `data` object whose internal structure is not fully documented in the available material. The x402 challenge confirms the endpoint is live and returns a valid v2 payment challenge with two accepted payment options.
EruditePay Bridge is a FinCEN-registered MSB (BSA ID 31000324258137) that supports 20 blockchains for x402 payment facilitation. The price-impact endpoint is one of several "crypto data intelligence" services offered behind x402 paywalls. Documentation beyond the landing page and the x402 challenge schema is sparse — the `/docs` path returns a 404, so the exact fields inside the `data` response object are unknown.

}Endpoint
Quality
The endpoint is live (402 challenge captured) with a clear price and basic input schema, but the response data structure is entirely opaque (example shows empty `data: {}`), and the dedicated docs page returns 404. The actual fields returned in a successful paid call are unknown.
Warnings
- —Response schema is undocumented — the example output contains an empty data object, so the actual fields are unknown.
- —The /docs path returns 404; no external documentation was found for this specific endpoint.
- —Only the Base chain is served by this endpoint despite the provider supporting 20 chains.
