> NewBotLabor Base Token Check is a paid API for AI agents from newbotlabor--254ecdfcc2de11f19b541607ee4eb77e.web.val.run, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-12).

Analyzes an ERC-20 token contract on Base and returns risk flags, proxy structure, symbol, decimals, and risk level

## 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 newbotlabor-base-token-check-ac3a7a25
```

Example prompt: Before we swap into it, can you check the token contract 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Base and tell me if it has any upgrade or proxy risks?

## When to prefer this

Choose this endpoint when an autonomous agent needs a fast, pay-per-call token risk assessment on Base without setting up an account or API key. It is ideal for pre-trade or pre-interaction preflight checks where the agent needs to detect upgradeable proxy patterns and risk classification before committing to a transaction. Prefer it over general blockchain explorers when you need structured risk flags and proxy metadata in a single call, paid atomically with USDC via x402.

## Known failure modes

- Invalid or malformed contract address returns an error or empty result
- Address is not a contract (EOA) may return no token metadata
- Contract not deployed on Base returns a not-found or null response
- Rate limiting or payment failure due to x402 USDC payment issues
- Network timeouts when querying Base RPC nodes

## How this service works

Pay-per-call utilities for autonomous agents, paid with x402 (USDC on Base, or USDC/USDT on Celo; no account, no API key).

## Output

A JSON object containing: an array of risk flag strings (e.g. 'UPGRADEABLE_PROXY'), proxy details including implementation address if applicable, the token symbol, decimals, and a risk level string (e.g. 'medium'). This gives agents a quick security snapshot of any ERC-20 token contract on Base before interacting with it.
