# Claw Hunter API

> Claw Hunter is one API for chat, image, and video models, priced about half of provider list.
>
> It speaks OpenAI's format at https://mystudios.fun/api/v1 and Anthropic's at https://mystudios.fun/api. OpenAI SDKs, Claude Code, Codex, Cursor, Hermes, OpenClaw, and other agents work by changing the base URL.
>
> The chat menu has 39 models, including Claude Fable 5.1, Claude Opus 5.5, GPT-6 Astra, GPT-6.1 Sol, Kimi K3, Grok 4.7. It's served on /chat/completions, /messages, and /responses, billed per token.
>
> The media menu has 40 image and video models, including GPT Image 2.5 Flare, GPT Image 2.5 Sunburst, Nano Banana Pro. It's served on /images/generations and /videos/generations, billed per image or per render.
>
> Send model clawhunter/smart and Smart Router picks the best model for each request. Send clawhunter/free for the day's featured free model.
>
> One API key pays for everything from prepaid credits (1 credit = $1, no expiry). Every account with a key gets free usage each day. Keys are at https://mystudios.fun/account.
>
> Without a key, /chat/completions and the media endpoints can be paid per call with x402, in USDC on Solana or Base or USDG on Robinhood Chain. Paying in $CLAWHUNTER, $SQUIRE, or $ANSEM on Solana, or $CASHCAT on Robinhood Chain, takes 10% off.

Free endpoints (the model menus) need no key and are rate-limited per IP. Paid endpoints take an API key (Authorization: Bearer chk_…) and bill its prepaid credits. Without a key, /chat/completions, /images/generations, /videos/generations, and /account/credits/purchase answer HTTP 402 with the price and every payment option; pay with x402 and send the call again. The $CLAWHUNTER mint is 6GGY8GViCR5v4xR4Lxb4nfiAJsEoJua5Gj6YecxbJ4BQ; the other mints are in the 402 options. $CASHCAT settles through Permit2, so approve Permit2 for $CASHCAT once on Robinhood Chain before paying with it.
