AI Agent Stack for Paris and the EU AI Hub in France

A French product group often has the model already. It still rents data, the agent run, and code execution from different vendors. SandBase is the single account:

• 2,000+ models and data APIs on 100+ platforms, paid from one balance
• Agents kept on file and Sessions you open, in the OpenAI Agents and OpenAgentCore shapes
• An E2B-compatible sandbox when the task must touch files or run a command
• SKILL.md so a coding assistant can find the catalog

Agents and sandboxes can start with no charge. Eligible data APIs share 100 free calls per day per organization, and the allowance resets at 00:00 UTC. Model tokens bill separately—read the listing before a long job.

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

These public pages describe the city. They are not a SandBase office.

• Startup Genome’s Paris profile for the Global Startup Ecosystem Report 2026 ranks Paris #13 globally and #2 in Europe, #2 in Europe for talent, and inside the global top 10 for its AI-native cluster. The page calls Paris Europe’s AI powerhouse.
• STATION F describes itself as the world’s biggest startup campus, based in central Paris, and says more than 1,000 startups call it home each year.
• CNRS describes the Centre national de la recherche scientifique as France’s largest public scientific research organization.

That is the demand this page is for: a Paris team shipping into the EU, with one API rather than a new contract for every tool.

1. Create the shared SandBase API key in the Console.
2. Write the Agent with its model, instructions, and tools, using POST /v1/agents or the OpenAI SDK.
3. After projection_status reads ready, open a Session and send the work.
4. Point the E2B SDK at https://sandbox.sandbase.ai if the task needs files or a script.
5. Or give the assistant SKILL.md so it can discover a tool, inspect it, and run it.

SandBase’s documented OpenAI Python SDK pattern, with instructions for Paris and EU 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="Paris EU brief",
    instructions=(
        "Write for a Paris and European Union product audience. "
        "Compare more than one source and cite each."
    ),
    metadata={"city": "paris", "team": "eu"},
)

print(agent.id, agent.version)  # agt_..., 1
# Hold the Session until projection_status reads 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_..."}'

Scripts and files belong in a sandbox. Follow the Sandbox quickstart.

If you searched for an AI agent API Paris teams can use without leaving the OpenAI Agents SDK, SandBase is that API. The same key serves builders elsewhere in France and the EU.

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

• Startup Genome — Paris ecosystem
• STATION F
• CNRS

The rankings are Startup Genome’s. STATION F’s site is the source for the campus description and the startup count. CNRS’s English site is the source for its description as France’s largest public scientific research organization. SandBase does not claim a public Paris phone number or a city-specific latency SLA on this page.
