Introduction

Overview of abliteration.ai’s HTTP APIs — base URL, authentication, and how the OpenAI-compatible and Anthropic-compatible surfaces are exposed.

abliteration.ai exposes HTTP APIs compatible with both the OpenAI and Anthropic SDKs. Point any client library at our base URL and you’re done.

Base URL

https://api.abliteration.ai/v1

The same base URL serves both API surfaces:

Path	Surface	Reference
/v1/chat/completions	OpenAI	Chat Completions
/v1/responses	OpenAI	Responses
/v1/messages	Anthropic	Messages
/v1/messages/count_tokens	Anthropic	Count tokens
/v1/models	OpenAI	Models

Authentication

All requests require a bearer token:

Authorization: Bearer $ABLIT_KEY

See Authentication.

Example

curl https://api.abliteration.ai/v1/chat/completions \
  -H "Authorization: Bearer $ABLIT_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "abliterated-model",
    "messages": [{"role": "user", "content": "Hello"}]
  }'

Versioning

The API is stable and backwards-compatible. Deprecations are announced in release notes with at least 30 days of notice.
