One AI API key for text, image, video, and code models
Call many different models through one base URL and one API key, so existing OpenAI-style clients and SDKs usually need only minor changes.
Access text and reasoning models alongside image, video, and audio/music generation endpoints from the same integration.
Route routine traffic through a value tier to reduce spend, and move critical workloads to an official tier when stability matters more than cost.
Manage credentials and usage in one place instead of juggling separate accounts, quotas, and invoices across vendors.
Build and share random generators for free with lists and simple code
Define items as lists and let Perchance pick randomly, producing names, items, prompts or full paragraphs.
Customize how your generator looks and behaves with standard web markup, styling and scripts.
Publish generators instantly so anyone can open and use them from a shareable page.
Browse and reuse generators created by the community, from RPG tools to story prompts and AI apps.
