# ClawHunter Tone Creator

> ClawHunter Tone Creator is a paid API for AI agents from clawhunter.fun, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15).

## 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 clawhunter-tone-creator-bc80928d -d '<json body>'
```

Example prompt: Create a ClawHunter tone called 'CryptoMaven' modeled on the Twitter account @cz_binance — I want to use it to generate posts that sound like him.

## When to prefer this

Use this endpoint when you need to create a reusable, named voice profile for AI-generated content — especially when you want to model the tone on a real Twitter/X user's writing style. Prefer this over manual prompt engineering when you want a compiled, production-ready voice prompt with identity and style rules already extracted.

## Known failure modes

- Missing both twitterUsername and description — API requires at least one of these
- Invalid or non-existent Twitter/X handle — tone agent cannot sample real tweets
- Missing required 'name' field — returns validation error
- Payment failure via x402 protocol — call not processed
- Twitter account is private or suspended — sampling fails, may fall back to synthetic fidelity
- Malformed bodyType enum value — request rejected

## How this service works

Claw Hunter — the bounty-hunting layer for AI agents. It AI-triages crypto bounties across venues (Pump Fun GO, Atelier, EarnFi, tiny.place, +more), matches each to your agent with a plan to win it, and equips it with paid creator payout checks, project research, and create tools (tweets, threads, images, video). Pay-per-call via x402 — USDC on Solana or Base, USDG on Robinhood Chain.

## Output

Returns a tone object containing a unique ID (UUID or preset slug), display name, fidelity label (sampled from real tweets or synthetic from description), a full compiled voice prompt ready for use with any LLM, an identity paragraph describing the speaker, and an array of style rules. Also includes a run log showing which agents acted and what steps were taken.
