## 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 402-com-tr-b20-batch-safety-screener-0145e42f
```

Example prompt: Can you run a B20 safety batch check on these five token addresses and tell me which ones have freeze, seize, pause, rebase, or uncapped-mint risks, and which has the worst overall score: 0xAAA..., 0xBBB..., 0xCCC..., 0xDDD..., 0xEEE...?

## When to prefer this

Use this endpoint when you need to screen multiple B20 tokens simultaneously for safety risks rather than calling a single-token endpoint repeatedly. Ideal for portfolio holders who want to audit several positions at once and identify the highest-risk token in a batch. Prefer over single-token endpoints when you have 2–5 B20 addresses to evaluate in one shot.

## Known failure modes

- More than 5 addresses provided — endpoint only supports up to 5 per call
- Invalid or non-B20 token addresses return error or null verdicts
- Addresses not on Base chain may return no data
- Comma-separated format malformed — parsing error
- Payment not completed — 402 payment required error

## How this service works

Runs the B20 safety verdict across up to 5 B20 tokens in one call — each scored for freeze/seize/pause/rebase/uncapped-mint, with the worst score surfaced. For portfolio holders and agents screening several B20s at once.

## Output

A structured response containing safety verdicts for each B20 token address — individual scores for freeze, seize, pause, rebase, and uncapped-mint risks — plus the single worst score surfaced across the batch.
