# x402-seller /screen — Batch Token Rug-Check Watchlist

> x402-seller /screen — Batch Token Rug-Check Watchlist 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 2026-09-13).

Batch-screens a list of token contract addresses for rug-pull risk by fusing GoPlus static analysis, live Honeypot.is buy/sell simulation, serial-rugger detection, and self-collected liquidity-drain trends into a single ranked safety report.

## 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-screen-batch-token-rug-check-watchlist-b817b3db
```

Example prompt: Screen these token addresses on Base for rug-pull risk and rank them safest-first: 0xABC123..., 0xDEF456..., 0x789GHI... — I need to know which ones are honeypots or showing liquidity drain before I buy.

## When to prefer this

Choose this endpoint when you need to screen multiple token addresses in a single call rather than one-by-one, and want a fused safety score that combines static contract analysis, live simulation, and real-time liquidity-drain trends — especially useful for watchlist monitoring, portfolio audits, or pre-trade due diligence on a batch of candidates. Prefer over stitching free APIs when agent inference cost and latency matter, or when honeypot simulation and liquidity drain signals are required together.

## Known failure modes

- Invalid or malformed contract address returns an error or empty result for that token
- Unsupported chain identifier causes the request to fail or fall back to default chain
- Rate limiting or payment failure (insufficient USDC) returns 402 Payment Required
- Token too new or with no liquidity data may lack honeypot simulation results
- Network timeout from underlying GoPlus or Honeypot.is APIs can cause partial results

## 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 structured safety report for each submitted token address including a composite rug score fusing static analysis, live buy/sell simulation results, serial-rugger flags, and self-collected liquidity-drain trend signals — ranked safest-first so the agent can immediately identify which tokens to avoid.
