How Umbra sees your SDK call same wire · two envelopes
Both SDKs ride the same internal core: trust-level routing, prompt-hop crypto, and the token meter. Toggle the SDK above to highlight the active envelope.
OpenAI SDK
activefrom openai import OpenAI
client = OpenAI(
base_url="https://api.tryumbra.dev/v1",
api_key="umbra-...")
resp = client.chat.completions.create(
model="gemma-4-12b-coder-fable5",
messages=[{"role":"user","content":"Write a haiku..."}],
extra_body={"trust_level":"hardware"})
for chunk in resp:
print(chunk.choices[0].delta.content or "", end="")
client = OpenAI(
base_url="https://api.tryumbra.dev/v1",
api_key="umbra-...")
resp = client.chat.completions.create(
model="gemma-4-12b-coder-fable5",
messages=[{"role":"user","content":"Write a haiku..."}],
extra_body={"trust_level":"hardware"})
for chunk in resp:
print(chunk.choices[0].delta.content or "", end="")
Standard /v1/chat/completions surface. Umbra-specific extension is extra_body.trust_level.
Anthropic SDK
switch →from anthropic import Anthropic
client = Anthropic(
base_url="https://api.tryumbra.dev",
api_key="umbra-...")
msg = client.messages.create(
model="gemma-4-12b-coder-fable5",
max_tokens=1024, # required
messages=[{"role":"user","content":"Write a haiku..."}],
extra_body={"trust_level":"hardware"})
print(msg.content[0].text)
client = Anthropic(
base_url="https://api.tryumbra.dev",
api_key="umbra-...")
msg = client.messages.create(
model="gemma-4-12b-coder-fable5",
max_tokens=1024, # required
messages=[{"role":"user","content":"Write a haiku..."}],
extra_body={"trust_level":"hardware"})
print(msg.content[0].text)
/v1/messages surface. Same key. Anthropic-specific: max_tokens is required and anthropic-version is read on the wire.
