Otto AI — Token Top Holders
x402
Otto AI — Token Top Holders is a paid API for AI agents from x402.ottoai.services, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-13).
Returns the top token holders, concentration metrics, and entity labels for a Base ERC-20 token contract address
Price / call$0.02
Success—
StatusUnknown
How this service works
Top holders for any Base ERC-20 (via Moralis), with computed concentration (top1/5/10/20% + contract-held%) and optional whale-risk read. Curated hot set refreshed hourly; long-tail tokens write-through on first call.
Output
Returns a ranked list of top token holders including owner addresses, USD value held, percentage of total supply, entity labels (e.g. Uniswap, Coinbase), contract vs EOA flags, and an AI-generated narrative summarizing concentration risk. Also includes aggregate stats: top-1/5/10/20 pct of supply, contract-held pct, and total supply.
Example use cases
Example prompt
“Who are the top holders of the DEGEN token on Base (contract 0x4ed4e862860bed51a9570b96d89af5e1b0efefed)? Show me their balances, what percent of supply they hold, and whether the token is whale-concentrated.”
Technical details
Endpoint
GEThttps://x402.ottoai.services/token-top-holdersWhen to prefer
Use this endpoint when you need detailed holder concentration analysis for a specific Base ERC-20 token, including entity identification, whale detection, and an AI-generated summary of distribution risk. Prefer this over generic blockchain explorers when you want labeled entities, structured concentration metrics, and a narrative interpretation in a single API call.
Side effects
- Invalid or non-Base ERC-20 contract address returns an error
- Token with no on-chain holder data may return empty holders list
- Stale data if generatedAt timestamp is old and validUntil has passed
- Payment failure if USDC balance is insufficient for x402 $0.02 fee
- Unsupported token or chain returns no results

While approximately 39% of the supply is held within smart contracts (likely vesting, staking, or liquidity), five private EOA wallets control nearly 22% of the supply, presenting significant individual dump risk. The presence of a centralized exchange hot wallet in the top 10 indicates active secondary market liquidity, but the heavy weight of unidentified private wallets remains the primary centralization concern.",
