How to use Instafill.ai?
Upload a fillable PDF form to the website. The AI will automatically complete the form using available data. Users can also upload a CSV file for batch form filling or create custom profiles to predefine sets of information.
How to use ApiModels?
1. Sign up at apimodels.app with Google or a phone number. You get $0.10 of free credit immediately — no credit card required. 2. Open Console → API Keys and create a key. 3. Call the endpoint for what you want to generate, with `Authorization: Bearer YOUR_API_KEY`: • Images — POST /api/v1/images/generations • Video — POST /api/v1/video/generations • Music / speech — POST /api/v1/audio/generations • LLM — POST /api/v1/chat/completions (OpenAI format) or /api/v1/messages (Anthropic format) 4. Pick a model by setting the `model` field, e.g. "gpt-image-2", "seedance-2.0", "suno-v5". Switching models means changing that one string — no new account, no new SDK. 5. Image and LLM calls return synchronously. Video, music and long-running image jobs return a taskId — poll the same endpoint, or supply a callback_url. Result files are hosted for 7 days. 6. Top up by Stripe, PayPal or Alipay when the free credit runs out. You are only charged for successful generations.
