How this service works
86 APIs for AI agents: web scraping and crawling to Markdown, AI summaries, data extraction and cited answers, screenshots and PDF, PDF, OCR and document conversion, news, paper and developer search and more, paid per call with USDC on Base, Solana, Polygon or Arbitrum via x402. No account, no API key, free sample on every service.
Output
Returns a JSON object containing the token's name, symbol, decimals, chain, chain ID, total supply (human-readable and raw), a block explorer URL, and optionally the specified holder's balance (human-readable and raw) along with a timestamp of when the data was checked.
Example use cases
Identify unknown token contract
“I found this contract address on Base — 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA — can you tell me what token it is, its symbol, and how many decimals it uses?”
Check wallet ERC20 token balance
“How many tokens does wallet 0x622efA6Ceb83a5b6EdBC931332f4db68B7f74F27 hold for the USDC contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base?”
Verify token supply before DeFi interaction
“Before I interact with this protocol, can you pull the total supply and metadata for the token at 0x6B175474E89094C44Da98b954EedeAC495271d0F on Ethereum so I know it's a legit ERC20?”
Technical details
Endpoint
POSThttps://agentsvc.io/api/v1/proxy/erc20-info?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured on-chain metadata about any ERC20 token — name, symbol, decimals, total supply — on Base or Ethereum, especially when you also want a specific wallet's token balance in the same call. Prefer this over block explorer scraping when you need machine-readable JSON without parsing HTML, and when you want pay-per-call pricing with no API key setup.
Side effects
- Invalid contract address format (must be 0x-prefixed 40-char hex) returns a validation error
- Contract address exists but is not an ERC20 token may return incomplete or empty metadata
- Unsupported chain value (not 'base' or 'ethereum') returns a schema validation error
- Network RPC errors or chain congestion may cause timeouts
- Holder address provided but holds zero tokens returns balance of 0 rather than an error
