Holder quality from a bounded sample

holder-hands costs $0.05 USDC. Pass an ERC-721 or ERC-1155 contract_address with chain set to ethereum, base, ink, or robinhood. Base is the default.

The route reads up to two holder pages and six recent transfer pages. It reports top-1, top-10, and top-50 supply concentration, the share of sampled holders with one token, and any non-contract wallet above 20% of supply.

Transfer metrics include the share of sampled token IDs that moved more than once, median time between those moves, and the mint-versus-secondary split. Wash signals count immediate A-to-B-to-A reversals, self-transfers, and the busiest wallet pair's share. The route reports telemetry counts without labeling wallets.

The verdict is strong_hands, mixed, churning, or insufficient_sample. The response includes the sampled time window and marks a transfer sample that hit its page cap.

This is data and risk telemetry, not investment advice.
