## 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 b20-launch-radar-newest-b20-tokens-on-base-fb745ddc
```

Example prompt: Show me the 20 newest B20 tokens just launched on Base — I want to see their symbols, variants, and which blocks they were created in so I can scout early launches.

## When to prefer this

Use this endpoint when you need a live discovery feed of brand-new B20 token launches on Base — ideal for agents scanning for early token opportunities, monitoring the B20Factory output, or building launch-alert workflows. Prefer this over wallet or transfer endpoints when the goal is discovery of new tokens rather than analysis of existing ones.

## Known failure modes

- No new tokens found returns empty list
- Invalid limit parameter type returns 400
- Service unavailable or upstream precompile query fails returns 5xx
- Payment not fulfilled returns 402

## How this service works

🆕 Lists the newest B20 tokens created on Base (from the B20Factory precompile) — variant, symbol, decimals, block. B20 is Base's native token standard and dozens launch hourly. A discovery feed for agents hunting new B20 launches early. Run b20-safety on any address before touching it — new ≠ safe.

## Output

A list of the most recently deployed B20 tokens on Base, each entry including the token contract address, symbol, variant type, decimal precision, and the block number at which it was created — ordered newest first.
