## 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 flaunch-memecoin-launch-via-x402-8be02393 -d '<json body>'
```

Example prompt: Launch a memecoin on Flaunch called 'PepeCat' with ticker PCAT — here's the description: 'The internet's favorite cat-frog hybrid coin' — use this PNG image I'll attach, and attribute it to my wallet 0xAbCd1234AbCd1234AbCd1234AbCd1234AbCd1234.

## When to prefer this

Choose this endpoint when you need to programmatically launch a new memecoin on the Base blockchain via the Flaunch platform with a $1 anti-spam gate. It is ideal for agents automating community token launches, creator coin deployments, or any workflow that requires on-chain token creation with custom name, symbol, image, and creator attribution. The idempotency key makes it safe for retry-prone agentic workflows. Prefer this over generic token deployment tools when you specifically want a Flaunch-listed token on Base.

## Known failure modes

- Payment failure: x402 payment of $1.00 USDC not completed or rejected — token is not launched
- 409 Conflict: idempotency key reused with a different payload — returns conflict error
- 422 Validation error: name exceeds 32 chars, symbol exceeds 10 chars, description exceeds 255 chars, or image exceeds 5MB or is an unsupported format
- Invalid creatorAddress: EVM address does not match 0x + 40 hex chars pattern
- Image encoding error: imageBase64 is not a valid base64 data URL
- Rate limit or network error on Base chain deployment

## How this service works

Launch a Base memecoin via Flaunch after a $1.00 x402 anti-spam payment.

## Output

On success (HTTP 202), the agent receives confirmation of the launched token including the deployed contract address on Base, a transaction hash, and a link to the Flaunch listing page. If the same idempotency key is reused with the same payload, the original response is returned without re-charging. A 409 is returned if the idempotency key is reused with a different payload.
