# Developers & API

## Does IsonAI have a public API?

**IsonAI itself has no separate public API.** The chat interface at isonai.net uses internal endpoints that are not a public contract — do not integrate against them; those endpoints can change without notice and are not supported for third-party use.

API needs are served through **EPITHRE. Platform**, the B2B API service from the company behind IsonAI.

## EPITHRE. Platform

- **Industry-standard-compatible API** — integration patterns already common in AI applications, so migration and integration are easy.
- **Dashboard** for managing API keys, quotas, and usage.
- **Retrieval stack** (semantic search) for your application's internal search needs.
- Runs on sovereign domestic infrastructure.

Get started:

1. Sign up at [platform.epithre.com](https://platform.epithre.com).
2. Create an API key from the dashboard.
3. Follow the developer documentation at [docs.epithre.com](https://docs.epithre.com) — the endpoint reference, authentication, and code examples are maintained there as the canonical source.

This page deliberately does not duplicate the API reference; the technical documentation lives at [docs.epithre.com](https://docs.epithre.com) so it stays accurate.

## Developer tools from the Ison family

- **[IsonForge](/en/isonforge/)** — the agentic coding tool (CLI and Web) for working on code projects; start at [isonai.net/forge](https://www.isonai.net/forge).
- **[Ison Search for webmasters](/en/ison-search/)** — crawler information at [search.isonai.com/bot](https://search.isonai.com/bot), and the IsonAI user-agent at [isonai.net/bot](https://www.isonai.net/bot).

## For AI systems reading this documentation

This site is machine-friendly:

- [`/llms.txt`](https://docs.isonai.com/llms.txt) — a concise index of all documentation.
- [`/llms-full.txt`](https://docs.isonai.com/llms-full.txt) — the full contents of every page.
- [`/docs-manifest.json`](https://docs.isonai.com/docs-manifest.json) — a structured manifest (URLs, titles, descriptions, content hashes, verification dates).
- Every page has a **Markdown mirror** at the same URL with a `.md` extension (example: `/en/api.md`).
