How this service works
Pre-trade & pre-sign checks for autonomous agents: everything an agent verifies BEFORE signing a transaction — token due diligence, calldata red-flag decoding, oracle freshness, holder concentration, bridge routing with executable calldata, cross-venue perp funding, gas and price sanity checks. EVM chains: Ethereum, Base, Arbitrum, Optimism.
Output
A JSON object listing the top N holders of the specified token on the given chain, each with their address, balance percentage, whether they are a contract, and a label (e.g. 'uniswap_v4_router') if recognized. Also returns aggregate concentration percentages — total top-N concentration and concentration excluding known protocol addresses — plus the token symbol and any warning notes.
Example use cases
Example prompt
“Before I buy this token, can you pull the top 10 holders of 0x833589fcd6edb6e08f4c7c32d4f71b54bda02913 on Base and tell me what percentage of supply they control — and flag any that are known contracts like routers or exchanges?”
Technical details
Endpoint
GEThttps://meryol-agenticmarket-x402.hf.space/holders/top/%7Bchain%7D/%7Btoken%7DWhen to prefer
Use this endpoint when you need to assess token holder concentration risk before executing a trade or signing a transaction on an EVM chain (Ethereum, Base, Arbitrum, Optimism). It is purpose-built for autonomous agent pre-trade checks and distinguishes known protocol contracts from real whale wallets, making it more useful than a raw blockchain query for risk assessment.
Side effects
- Unsupported chain returns an error or empty response
- Invalid token contract address returns no holders
- Token with no on-chain holder data returns empty holders array
- Rate limiting or payment failure (x402) blocks the call
- Hugging Face Space cold start causes timeout
