# Tali Agent Tools – Token Exit Check

> Tali Agent Tools – Token Exit Check is a paid API for AI agents from tali-agent-tools.talibot.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-20).

Simulates a round-trip buy/sell of a Base ERC-20 token to detect taxes, pool fees, price impact, and whether it's safe to exit a position.

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 tali-agent-tools-token-exit-check-ba41628f
```

Example prompt: Check if I can safely exit my position in the Base token at 0xFF0C532FDB8Cd566Ae169C1CB157ff2Bdc83E105 — simulate a round-trip with 0.001 ETH and tell me the buy and sell taxes, total loss, and whether it's safe to sell.

## When to prefer this

Use this endpoint when you need to programmatically verify whether a specific Base ERC-20 token can be sold without excessive tax or price impact, especially before executing a trade or listing a token. Prefer it over manual DEX checks when you need structured machine-readable output (tax %, loss %, verdict) that can drive downstream automation. It is specifically designed for Base mainnet tokens and uses actual on-chain simulation rather than static contract analysis.

## Known failure modes

- Token address not found on Base – no liquidity pools available
- Invalid token address format – must be a checksummed 0x address
- Simulation reverts – token may be a honeypot or have blocked sells
- Amount outside supported range (0.0001–1 ETH) returns validation error
- Payment failure via x402/PayAI – USDC balance insufficient or facilitator error

## How this service works

x402 v2 paid agent tools on Base mainnet USDC via PayAI facilitator.

## Output

Returns a JSON object with an exit verdict ('exit_ok' or similar), market data (symbol, price, liquidity, volume, pair age), and a detailed simulation result including buy tax %, sell tax %, transfer tax %, round-trip loss %, the DEX and pool used, pool kind (v2/v3), and any revert reason if the simulation failed.
