HolderScan API

by @HolderScanCOMMUNITY· Updated Nov 10, 2026

HolderScan's API returns holder counts, distribution, wallet categories and holder PnL for Solana and Ethereum tokens, so your agent can check who holds a token next to Moby.

About

HolderScan tracks token holder data: holder counts and deltas, distribution stats (HHI, Gini, median holding, time held, retention), wallet categories, supply breakdowns and holder PnL. Its beta REST API (V0) covers Solana (sol) and Ethereum (eth) and needs an x-api-key. Standard API access comes with HolderScan Premium; larger API plans are listed at https://holderscan.com/api-plans.

What it adds to Moby. A second read on holder quality: how concentrated a token is, whether holders are growing or leaving, and how long they hold. Moby adds smart money, KOL and execution.

How to pair it. Pull holder breakdowns and deltas for a token, then compare with get_token_key_holders and get_token_smart_money on Moby. Rising holders with strong retention plus smart money buying is a stronger setup; trade it on Moby.

What it does not do. It does not trade, custody funds or offer an MCP server. It is a read-only REST API. If you show HolderScan data in an app, site, bot or chart, credit HolderScan with its name, logo and a link to holderscan.com.

  • Holder counts and holder deltas by time window
