How this service works
Machine-payable data APIs for AI agents — 35 endpoints across web search, on-chain reads, trading data, and AI-visibility. Pay per call in USDC via x402 on Base. No API keys, no signup.
Output
A JSON object containing the token's name, symbol, contract address, chain, total supply (raw integer), number of holders, USD price, market cap in USD, and decimal precision — all sourced from on-chain reads.
Example use cases
Example prompt
“What is the total supply, holder count, and USD price for the USDC token at contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum?”
Technical details
Endpoint
GEThttps://x402-agent-store.rileycraig14.workers.dev/chain/supply?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need on-chain token supply, holder count, or price data for a specific ERC-20 contract address across major EVM chains (Ethereum, Base, Arbitrum, Optimism, Polygon, Gnosis). Prefer this over general market APIs when you have the contract address and want canonical on-chain figures rather than exchange-reported data. It requires no API key — only a micro-payment of $0.001 USDC via x402 on Base.
Side effects
- Invalid or non-existent contract address returns an error or empty response
- Unsupported chain name causes a validation error
- Token with no holder data may return holders as null or 0
- Non-ERC-20 contract address may return malformed or missing fields
- Rate limits or payment failure (402) if USDC payment is not properly attached
