API access and integration for developers

API integration needs authentication and a clear contract. Adapt transport examples to documentation for the installed version.

These steps refer to features identified in the application code. This material has not been validated on a live instance; check the documentation and the options in your version.

How it works, step by step

Contract and example data

Document request target, conversation identifier, timeout and stream consumption. Consult API documentation for endpoints and schemas. Do not reuse a generic body across Playground, chat and RAG: their contracts can differ. The minimal example below illustrates intent, not a guaranteed HTTP payload.

The visual map

Follow the solid arrows for the main flow. Dashed blue arrows supply data or context; dashed pink arrows show feedback or returning results. Colors and shapes distinguish models, stores, decisions and outputs. On smaller screens, scroll horizontally to follow the entire diagram.

A complete example

Your backend calls chat with target and organization/project context, reads the stream and handles errors. Secrets remain in the backend, not the browser.

{"intent":"ask_policy","target":"fictional-agent","question":"What is the return deadline?"}

Try it yourself

1. Open API documentation and verify headers, body and response schema before calling.
2. Record the input, source and expected outcome before running the experiment. Use only the fictional data in the example.
3. Follow the diagram stages. At every step record what information is received and produced; do not confuse intermediate output with the final outcome.
4. Repeat after removing necessary information or making the input ambiguous. Check whether the system clarifies, stops or invents an answer.
5. Compare with the explained solution. Keep the configuration, date, result and an explanation for differences. Change one thing and retest.

An explained solution

The client distinguishes final response, timeout and access denial without leaking the key. A successful exercise lets you show the connection between input, stages and outcome. When information is missing, a cautious answer is more useful than invented details. Compare more than style: check conditions, sources and operations too.

When it helps and what can go wrong

A deployment MCP key is not automatically an organization API key. Choose this approach when it improves a measured need. Keep a simple baseline and compare outcomes using identical inputs. One successful example does not establish reliability in every situation.

Check your understanding

Why is removing a private source after answering too late?

The data has already entered model context and can be disclosed.

Who executes a call proposed by the model?

The application or host service after validation. The model does not automatically gain unrestricted access.

What outcome should this exercise produce?

The client distinguishes final response, timeout and access denial without leaking the key.

Words to remember

• Autorizare / Authorization: Checking the right to access an operation or resource.
• Tool calling: A structured request to use an external capability.
• Idempotency: Controlled repetition without duplicating an effect.
