Fireworks: get an API key and write fiction with it on your phone

A fast-moving serverless inference cloud: new open models land day-0, cached input is half price by default and batch inference runs at 50% too; everything from $0.10/M small models to DeepSeek and Kimi flagships bills per token with no cold starts. This page is the BYOK quick answer for Fireworks: key steps, direct console and pricing links, and the app-side notes that matter. Verified 2026-07-18.

Two links up front: get your key at the official console and check rates on the official pricing page. Prices and free quotas move; the official pages are authoritative.

What does it power inside Foreverse?

The factory preset declares 1 modality flag for Fireworks. The models actually available come from the live catalog fetched in-app — catalogs move fast, and the flag only means the protocol wiring is ready.

How do I get a Fireworks API key?

  1. Sign up at fireworks.ai — new accounts start with $1 in credits.
  2. Create a key under app.fireworks.ai → Settings → API Keys and copy it.
  3. To lift the card-less cap of 10 requests/minute, add a card and credits — the ceiling rises to 6,000 requests/minute.

Key in hand: three steps to connect

  1. Open the app's Settings → AI models & services and find Fireworks in the list (one of 62 presets, with logo and search).
  2. Paste the key and tap the connectivity test — it fires one real request to verify key and network, and pulls back the model list while it's at it.
  3. Enable the models you want, then set per-modality defaults (text, image, speech, and video each get their own); continuation, chat, and listening route through them from then on.

The one universal host pitfall: the API host must include its full version prefix (this provider's exact form is in the notes below) — the app never appends /v1 for you.

Fireworks-specific notes

The preset host is https://api.fireworks.ai/inference/v1 — the full prefix is /inference/v1, so don't drop /inference when typing it. Model IDs use the long accounts/fireworks/models/… form; copy the full ID from the model library. Prepaid: service stops when credits run out.

FAQ

Does Fireworks have a free tier?

New accounts get $1 in starter credit (roughly 1M tokens on a 70B-class model); there are no permanently free models. Card-less accounts cap at 10 requests/minute, rising to 6,000 with a card and credits.

Where does the key live once I paste it into the app?

It's stored on your device only, under system-level encryption — never uploaded or synced to any Foreverse server. Requests go straight from your phone to the provider's official endpoint with zero markup. To revoke access, delete the key in the provider's console.
