# APEX Base Token Verdict

> APEX Base Token Verdict is a paid API for AI agents from apexfaucet.xyz, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-19).

Returns a scored verdict (grade, roast, rubric, one-liner) for a Base network token contract address, checking for red flags and exit liquidity signals.

## 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 apex-base-token-verdict-9e35ee34
```

Example prompt: Can you run the APEX base-verdict check on the token at 0x4200000000000000000000000000000000000006 on Base and tell me its grade, roast, and whether it's flagged as radioactive?

## When to prefer this

Use this endpoint when you need a fast, opinionated safety verdict on a specific Base network token contract — including a human-readable grade, roast, and rubric — rather than raw on-chain data. Ideal for pre-trade screening, alerting pipelines, or user-facing token safety UX where a plain-language summary is more useful than raw metrics.

## Known failure modes

- Invalid token address format (not 0x + 40 hex chars) — likely returns ok:false or 400 error
- Token not found on Base — may return empty data or ok:false
- Payment failure or insufficient USDC balance — x402 payment rejected
- Token has no liquidity data — measured metrics may be empty or partial
- Rate limiting or service unavailability — returns error response

## How this service works

Free APEX on X1, and free USDC plus APEX on Arc, three times a day. No gas, no sign-up. Plus a swap, a screener, APEX City and token checks.

## Output

Returns a JSON object with ok (boolean), a grade (e.g. BASED), a roast (short snarky summary), a rubric (e.g. RADIOACTIVE: buy or sell…), a one-liner, notes array, measured metrics, and a disclaimer. The paid field indicates cost charged.
