# Agent Data Tools – Base Token Lookup

> Agent Data Tools – Base Token Lookup is a paid API for AI agents from agent-data-tools.revmesh2074.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-11).

Looks up on-chain metadata for a token contract on the Base blockchain, returning name, symbol, decimals, supply, proxy info, and capability flags.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agent-data-tools-base-token-lookup-d0ae6a4e
```

Example prompt: Can you pull the on-chain details for the token at contract address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base — I want to know its name, symbol, decimals, total supply, and whether it has any mint or burn capabilities?

## When to prefer this

Use this endpoint when you need live, on-chain token metadata from the Base network specifically — including proxy architecture, capability flags, and ownership details — without needing a centralized token registry account or API key. It's ideal for DeFi agents performing pre-trade due diligence, smart contract audits, or balance formatting that requires accurate decimals, paid per-call in USDC with no subscription overhead.

## Known failure modes

- Invalid or malformed contract address returns an error
- Address is valid but not a token contract on Base — may return empty or error response
- Network or RPC unavailability causes timeout or 5xx error
- Payment not confirmed via x402 protocol results in 402 Payment Required response
- Token exists but is non-standard and some fields may be null or missing

## How this service works

Pay-per-call tools for AI agents: web page text extraction and summaries, screenshots, image generation, speech-to-text, image description, domain and email-auth intelligence, and live Base token and wallet lookups. No account or API key; pay per request in USDC on Base via x402.

## Output

Returns a JSON object with the token's name, symbol, chain, address, decimals, formatted total supply, owner address, ownership-renounced flag, paused status, proxy details (kind, admin, implementation, isProxy), and a capabilities object indicating whether the token supports mint, burn, pause, blacklist, and feeSetter operations.
