How this service works
Returns a concentration-risk score for an x402 pay_to wallet: HHI, unique payer count, top-payer share, persistence across scans, and a risk tier (LOW / MEDIUM / HIGH / CRITICAL). An agent uses this to assess whether an endpoint is a single-agent dependency before building a workflow that depends on it.
Output
Returns a concentration risk score for the specified wallet address, quantifying how concentrated or diversified its payment activity is over the given observation window (up to 30 days). Likely includes a numeric score and supporting metrics derived from on-chain payment data.
Example use cases
Example prompt
“What's the concentration risk score for wallet 0xAbCd1234567890abcdef1234567890abcdef1234 on Base, looking at the last 14 days of activity?”
Technical details
Endpoint
GEThttps://the-stall.intuitek.ai/cap/concentration-risk-scoreWhen to prefer
Use this endpoint when you need to evaluate how concentrated a wallet's incoming payment patterns are — for example, before making a payment to an address, during due diligence on a counterparty, or when building risk-scoring pipelines for blockchain addresses on Base mainnet. It is particularly useful when no account or API key management overhead is desired, paying per-call via USDC x402.
Side effects
- Invalid or malformed wallet address (not 0x-prefixed or not 42 hex chars) returns a validation error
- window_days exceeding 30 triggers a parameter error
- Wallet address with no on-chain activity may return a null or zero score
- Payment failure (USDC balance insufficient) results in 402 response and no data returned
- Network or on-chain data unavailability may cause a temporary service error
