# x402-seller Token Vet

> x402-seller Token Vet is a paid API for AI agents from x402-seller-m8nx.onrender.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Performs a composite rug-pull risk assessment on a single token address, combining GoPlus static analysis, live Honeypot.is buy/sell simulation, serial-rugger detection, and self-collected liquidity-drain trends into a go/no-go verdict.

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 x402-seller-token-vet-6cbc1a42
```

Example prompt: Before my trading bot buys this token, vet the contract 0xabc123...def on Ethereum — run the full rug check including honeypot simulation and liquidity drain trend to give me a go or no-go.

## When to prefer this

Choose this endpoint when an autonomous trading agent needs a single, authoritative go/no-go before entering a position — especially when the token is newly launched or unknown. It replaces four separate free-API calls (GoPlus, Honeypot.is, deployer history, liquidity snapshots) with one fused result, saving inference tokens and latency. Prefer it over raw GoPlus alone when live buy/sell simulation and liquidity-drain trend matter, and over Honeypot.is alone when you also need static contract analysis and rugger history.

## Known failure modes

- Unknown or unindexed token address returns empty or null result
- Unsupported chain identifier causes a bad-request error
- Token too new for liquidity trend data — drain signal may be unavailable
- Honeypot.is simulation fails transiently — composite score may be partial
- Payment not fulfilled (x402) — request is rejected before analysis runs
- Rate or USDC balance exhausted — further calls blocked until topped up

## How this service works

Rug protection and decision-ready intelligence for autonomous trading agents. Keyless by design: no signup, no API key — pay a cent per request in USDC (x402). The /alpha/launches LAUNCH RADAR discovers what just launched AND rug-screens every candidate in one call, ranked per-token verdicts — the proactive 'give me safe alpha' call. /vet gives a single-token go/no-go in ONE call by fusing a COMPOSITE rug score (GoPlus static analysis + a LIVE Honeypot.is buy/sell simulation + serial-rugger check) with our SELF-COLLECTED liquidity-drain trend — a rug-in-progress signal that exists nowhere for free because it requires collecting reserves over time. One call is cheaper than the inference tokens you'd burn stitching 4 free APIs, and it stops your agent losing its whole position to a honeypot. Also: /onchain/liquidity drain detector, /screen batch watchlist check, /brief market regime, and raw feeds (prices, stocks, DEX pools, launches, perp funding/OI).

## Output

Returns a composite rug risk score fusing GoPlus static contract analysis, a live Honeypot.is buy/sell simulation, a serial-rugger deployer check, and a proprietary liquidity-drain trend signal. The response includes a go/no-go recommendation and individual sub-scores so the agent knows exactly which risk factors triggered.
