How do I point at my Azure deployment?

Set x-azure-endpoint and x-azure-deployment headers (or configure them per-key in the dashboard). VerticalAPI rewrites the request to Azure's deployment-scoped URL format.

Are content filters preserved?

Yes. Azure content-filter results are surfaced as a content_filter_results field on the response, matching Azure's native shape.

Azure OpenAI via VerticalAPI

Supported models

Azure OpenAI models routed by VerticalAPI

Pass the model ID below as model in any OpenAI-compatible request. New Azure OpenAI models are typically supported within 24h of release.

Model ID	Name	Context	Pricing (provider)
`gpt-4o`	GPT-4o (Azure)	128K	Azure pricing — typically matches OpenAI
`gpt-4o-mini`	GPT-4o mini (Azure)	128K	Azure pricing
`text-embedding-3-large`	text-embedding-3-large	8K	Azure embeddings pricing

Pricing reflects Azure OpenAI's rates — you pay Azure OpenAI directly. VerticalAPI adds zero markup on tokens.

Quickstart

5-line Azure OpenAI call via VerticalAPI

Drop-in replacement for the OpenAI SDK. Works with the OpenAI Python client, Node, Go, curl — anything that speaks HTTP.

                azure-openai_quickstart.py
                Python
            
from openai import OpenAI

client = OpenAI(
    base_url="https://api.verticalapi.com/v1",
    api_key="vapi_...",
    default_headers={"X-Provider-Key": "Azure resource..."}
)

response = client.chat.completions.create(
    model="gpt-4o",  # Azure OpenAI

Why use Azure OpenAI via VerticalAPI

Four reasons developers route Azure OpenAI through us

Zero token markup

You pay Azure OpenAI directly with your own key. VerticalAPI's revenue is the gateway subscription, not a tax on your tokens.

One key, every provider

Azure OpenAI alongside OpenAI, Anthropic, Gemini and 12 more — same OpenAI-compatible endpoint, same SDK, switchable per-request.

Latency & cost monitoring

Per-request token counts, p50/p95 latency and cost dashboards out of the box. Compare Azure OpenAI to other providers on identical prompts.

Observability built in

Every Azure OpenAI call gets a trace ID, replayable payload and audit log entry. Wire to Datadog or Sentry via OpenTelemetry.

Frequently asked questions

What is Azure OpenAI and what models do they offer?

Azure OpenAI Service is Microsoft's enterprise hosting of OpenAI models on Azure. The 2026 catalog includes GPT-4o, GPT-4o mini, GPT-5, the o1 and o3 reasoning families, GPT-4 Turbo, text-embedding-3, DALL·E 3 and Whisper. All access requires deploying a model to an Azure resource in a chosen region, with quotas managed per deployment. Azure adds Entra ID auth, Private Link, customer-managed keys and SOC/HIPAA/FedRAMP certifications.

How much does Azure OpenAI cost in 2026?

Pay-as-you-go pricing mirrors OpenAI list: GPT-4o at $2.50/$10, GPT-4o mini at $0.15/$0.60, GPT-5 around $5/$15, o1 at $15/$60. Provisioned Throughput Units (PTUs) are sold in monthly or yearly reservations for committed capacity with predictable latency. Azure egress and Private Link fees apply. Via VerticalAPI BYOK you pay Azure directly with zero token markup.

How do I use Azure OpenAI via VerticalAPI BYOK?

Deploy a model in the Azure portal (e.g. gpt-4o), grab the endpoint URL, API key and deployment name, paste them into VerticalAPI, then point the OpenAI SDK at https://api.verticalapi.com/v1. VerticalAPI translates standard OpenAI requests into Azure's deployment-based URLs and api-version headers. Billing remains on your Azure subscription.

What is Azure OpenAI best for compared to alternatives?

Azure OpenAI wins for Microsoft-shop enterprises: Entra ID SSO, Private Link, Azure region residency, EU Data Boundary, and tight Microsoft 365 / Copilot integration. Compared to direct OpenAI it adds enterprise governance and regulatory certifications. Compared to AWS Bedrock it has narrower model selection (OpenAI only) but matches OpenAI on quality. Not the cheapest path — pay-as-you-go is OpenAI list, PTUs require commitment.

Where is Azure OpenAI hosted / data privacy?

Azure OpenAI runs in 25+ regions including East US, West Europe, France Central, UK South, Japan East and Australia. Inputs and outputs are not used to train OpenAI's models. Data stays in-region with EU Data Boundary option. Customer-managed keys (CMK), Private Link, abuse-monitoring opt-out and HIPAA/SOC 2/FedRAMP High are available. Via VerticalAPI BYOK your Azure account remains the data controller.

Limitations and trade-offs

Model availability lags OpenAI by weeks — new releases (GPT-5, o-series) appear later on Azure.
Deployment-based quotas and per-region capacity can require multiple deployments for scale.
Content filtering is on by default and stricter than direct OpenAI, sometimes blocking valid prompts.
PTU pricing requires committed monthly spend; pay-as-you-go has no SLA on latency.
API versioning (api-version=2024-…) is more cumbersome than the direct OpenAI SDK.

Where Azure OpenAI is heading

Faster model parity with OpenAI as Microsoft ships the partnership infrastructure.
Wider EU Data Boundary and sovereign cloud (Azure Government, Azure Germany) expansion.
Deeper Microsoft 365 Copilot integration with cross-tenant AI agents.
More flexible PTU sizing and on-demand reservations to compete with Bedrock.

All supported LLM providers

Same endpoint, same SDK — just change the model and the BYOK header.
