# Arc Token Immune Check (apexfaucet.xyz)

> Arc Token Immune Check (apexfaucet.xyz) is a paid API for AI agents from apexfaucet.xyz, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-30).

Runs a four-dimensional safety audit on an Arc token contract — exit simulation, fee analysis, launch bundle detection, and full holder history — returning a single letter grade and detailed evidence.

## 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 arc-token-immune-check-apexfaucet-xyz-6b2d2922
```

Example prompt: Can you run an immune check on this Arc token at 0xf5940f6250a9e705303ff7e6f287afa6c264f0ab and tell me if it's safe — I want the grade, whether the launch was bundled, and who the top holders are?

## When to prefer this

Choose this endpoint when you need a comprehensive, fused safety score for an Arc-chain token in a single call — especially when you want both structural checks (exit simulation, fees, liquidity) and social/behavioral checks (launch bundling, holder concentration) in one response with a verifiable evidence hash. Prefer it over manual on-chain queries when you need a quick A–F grade for agent-driven trading decisions or due diligence on Arc memecoins.

## Known failure modes

- Invalid or non-Arc token address returns an error or empty result
- Token with no liquidity pool may produce incomplete exit simulation
- Very new tokens with few Transfer events may have sparse holder history
- Rate limiting or payment failure results in 402 response
- Missing on-chain data (e.g. no pool) surfaces in the 'missing' array of evidence

## 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: a letter grade (A–F) and plain-English word (e.g. HEALTHY), a reasons array explaining the grade, and a detailed evidence object containing exit simulation results (simulated buy-sell round trip), pool fee, dynamic-fee hook status, liquidity-pull accessibility, bundle launch detection (launcher + funded wallets buying in first 2 minutes and their supply share), full Transfer-event replay producing top-10 holder balances and creator holding percentage, a checkedAt timestamp, and a verifiable evidenceHash (SHA-256 of canonical JSON). Also includes a link to a public verification page.
