Craftiest — the AI creation layer

Build, use and sell specialized AI

Craftiest is the AI creation layer. One key reaches every model and every capability, a studio turns that into an agent that does one job properly, and a marketplace makes it something you can put a price on.

How Craftiest works

  1. Build

    Compose a prompt, a model policy, tools, and your own knowledge into an agent that does one job properly.

    Open Studio

  2. Use

    Run it here, call it from your code, or embed it. One key, one balance, one bill — whatever it routes to underneath.

    Read the docs

  3. Sell

    Publish it, price it, earn on every run. Or sell the agent outright and hand over the title.

A router is table stakes. This is the whole shop.

Model aggregators solve one problem: picking a model. Specialized AI needs more than that — images, voice, search, retrieval, and orchestration, each with its own key, its own invoice, its own outage. Craftiest puts all of it behind one contract, so the hard part of your work is the thing you were actually trying to build.

  • One endpoint, every model

    OpenAI-compatible. Point your existing SDK at our base URL and you have every frontier model, with automatic fallback when a provider has a bad day.

  • Tools, not just tokens

    Image generation, speech, transcription, OCR, scraping, web search — the same key, the same balance, the same billing. No twelve dashboards.

  • Agents as artifacts

    An agent is a versioned object: prompt, model policy, tool bindings, knowledge. Run it here, call it over the API, or hand it to someone else.

  • A real marketplace

    Publish an agent and price it. Sell it once, subscribe it, or earn on every run. When you're done with it, sell the agent itself.

Agents you can actually own

Most agent directories are lists of links. Here an agent is an asset with a price, a version history, and a title you can transfer. Build one, price it, and let it earn. Sell it outright when you’re ready to move on — escrow holds the credits until the handover completes, and the original author stays on the record forever.

One balance
Credits cover inference, tool calls, and purchases alike. Top up by card or in USDC.
Spend that can't run away
Every request reserves credits before it runs. Per-key ceilings mean a loose loop costs you a limit, not a bill.
Creators get paid per run
Rev-share settles into the ledger the moment a run finishes — not thirty days later.
Versions are immutable
A published version can never be edited. Pin one, or follow the latest. What you bought stays what you bought.

Start with one key

Sign up, generate a key, and make your first call in under a minute. Bring your own provider keys later if you want — the router works either way.
