Hush0 API

Hush0 is one endpoint in front of every major AI model, with an honest privacy label on each, at prices below the labs. It is a drop-in replacement for the OpenAI chat endpoint.

OPENAI_BASE_URL=https://hush0.ai/v1
OPENAI_API_KEY=sk-hush0-…

Privacy labels

Label	Who can read the text	Models
sealed	Nobody. Decrypted only inside a verified enclave.	Llama 4 Maverick, DeepSeek V3 / R1, Kimi K2
private	The machine, for one moment. Zero retention.	Qwen3 235B, Mistral Large
anonymized	The lab that made the model. They see text, never you.	Claude Opus 5 / Sonnet 5 / Haiku 4.5, GPT-5, Gemini 2.5 Pro, Grok 4

Set X-Privacy-Floor: sealed and any request that would run on something weaker fails instead of downgrading.

Quick start

from openai import OpenAI
client = OpenAI(base_url="https://hush0.ai/v1", api_key="sk-hush0-…")
r = client.chat.completions.create(model="llama-4-maverick",
    messages=[{"role": "user", "content": "Summarize this lease in three lines."}])
print(r.choices[0].message.content)

Every response carries a receipt in its headers: X-Privacy-Level, X-Model, X-Weights-Sha256, X-Attestation, X-Cost-USD.
