AI Agent Stack for Sydney and Australia's Startup Capital

A lab or a product team in the city often already pays for a model. The data feed, the agent that holds the brief, and a machine for the script are still separate bills. SandBase is the account they can share:

• 2,000+ models and data APIs across 100+ platforms, drawn from one balance
• Kept Agents and opened Sessions, compatible with OpenAI Agents and OpenAgentCore
• A sandbox that speaks E2B when a job must read a file or run a command
• SKILL.md so the coding assistant can find the catalog

An Agent or a sandbox may start with no charge. Qualifying data APIs share 100 free calls a day per organization. That allowance resets at 00:00 UTC. Model use is billed on its own listing.

Call https://api.sandbase.ai/v1 with Authorization: Bearer $SANDBASE_API_KEY.

These public pages describe the city and the state. SandBase is not claiming a Sydney address.

• In the GSER 2026 Top 40, Sydney is #26 globally and #1 in Oceania. The Sydney section quotes Investment NSW: the city is building an innovation economy anchored by Tech Central, described as Australia’s innovation engine connecting talent, research, and industry. Startup Genome’s Sydney profile is the public page for that ecosystem.
• The University of Sydney says its engineering researchers build on work in artificial intelligence, machine learning, and autonomous systems. The same page describes computing and data platforms that power software and emerging agentic ecosystems, and a responsible-AI theme covering explainability, privacy, and the ethics of data collection.
• The NSW Government AI Strategy says AI is a tool to assist decision-making and service delivery, that an AI-informed decision stays the responsibility of the agency, and that no such decision is made unless the people affected can get a quick review.

SandBase is the API under that mix of a ranked startup city, a university robotics group, and a state rule that a person still owns the decision.

1. Create one key in the Console for the Australian organization.
2. Register the Agent with the OpenAI SDK or POST /v1/agents: a model, instructions, and tools.
3. When projection_status is ready, open the Session and send the task.
4. If the task needs files or a script, use the E2B SDK at https://sandbox.sandbase.ai.
5. Or give the assistant SKILL.md and let it look up the catalog first.

The OpenAI Python SDK pattern from the SandBase docs, with instructions for Sydney and Australian readers.

import os
from openai import OpenAI

client = OpenAI(
    api_key=os.environ["SANDBASE_API_KEY"],
    base_url="https://api.sandbase.ai/v1",
)

agent = client.beta.agents.create(
    model="deepseek/deepseek-v4-flash",
    name="Sydney startup brief",
    instructions=(
        "Write for a Sydney and Australian startup audience. "
        "Compare more than one source and cite each."
    ),
    metadata={"city": "sydney", "team": "australia"},
)

print(agent.id, agent.version)  # agt_..., 1
# Open a Session only after projection_status is ready.

curl -X POST https://api.sandbase.ai/v1/agents/sessions \
  -H "Authorization: Bearer $SANDBASE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"agent_id": "agt_..."}'

Keep scripts and files in a sandbox. Start with the Sandbox quickstart.

If you searched for an AI agent API Sydney teams in Australia can adopt while keeping the OpenAI Agents SDK, SandBase is that API.

Use these public pages. Do not add a SandBase office, a phone number, or a latency figure for Sydney:

• GSER 2026
• Startup Genome — Sydney ecosystem
• University of Sydney — AI and robotics
• NSW Government — AI strategy

The #26 global rank, the #1 Oceania rank, and the Tech Central line are Startup Genome’s for GSER 2026. The University of Sydney is the source for the robotics and agentic-ecosystems lines. The NSW Government is the source for the rule that an agency still owns an AI-informed decision. SandBase does not publish a Sydney phone number, a street address, or a city-specific latency SLA on this page.
