SnapGen is a prepaid AI gateway with OpenAI-compatible, Anthropic-compatible, and Gemini-compatible text protocols plus image and video generation APIs. Change your base URL to https://api.snapgen.org/v1, keep your API key on the server, and select a model ID from the live catalog.

​
Quick start

1

Create an API key

Create an account, add balance, then create a key under Console > API Keys.
2

Choose a model

Call GET /v1/models or browse the model pages in the sidebar. Model availability is scoped to your key.
3

Send a request

Send the key as Authorization: Bearer sk-... and use the endpoint for the selected modality.

​
API surfaces

Text Series

Use Chat Completions, Responses, Anthropic Messages, or Gemini native requests with the current GPT-5.4+ catalog.

Image Series

Generate images through the OpenAI-compatible image endpoint.

Video Series

Submit Gemini Omni, Seedance 2, or Veo 3.1 tasks, then poll and download.

Development tools

Configure Claude Code, Cursor, Cline, Gemini CLI, or Codex CLI.

​
Compatible text protocols

All four text protocols were verified against the live gateway. The gateway converts compatible requests to the selected model’s serving protocol.

​
Billing and availability

SnapGen uses prepaid USD balance with no subscription. Text routes are token-billed. GPT Image 2 and video routes use fixed or duration-based request prices.
The live models page is the source of truth for current availability and pricing. Call GET /v1/models before hardcoding a model ID.
