LlamaIndex

Pattern A · full governance

Point LlamaIndex's OpenAI LLM at the gateway with api_base. Queries, agents, and tools all route through Agentics.

Pattern A — routed through the gateway. Your call travels through Agentics via a base-URL swap, so it is governed (routing, budgets, guardrails) inline and the Proof Ledger writes one verifiable receipt server-side. The receipt hash comes back in the x-agentics-receipt response header.

Install

shell
pip install llama-index-llms-openai

Point the framework's OpenAI client at the gateway

The parameter is api_base; the equivalent env var is OPENAI_API_BASE.

Python
from llama_index.llms.openai import OpenAI llm = OpenAI( model="@anthropic/claude-opus-4-8", api_base="https://agentics.you/api/v1", # the only change api_key="ak_…", # AGENTICS_API_KEY default_headers={"x-agentics-user": "alice@acme.com"}, ) print(llm.complete("hi"))

You can also configure it via environment: OPENAI_API_BASE=https://agentics.you/api/v1.

Run one call → see the receipt

Run your normal invocation, then read the receipt for that call off the ledger:

shell
# after your run, the last call's receipt hash: agentics log tail --limit 1 # → shows x-agentics-receipt: <receipt_hash> (verify it at /trust)

Every call the framework makes is now routed, governed, and receipted server-side.
