Any API with a key

Any HTTPS API that takes a key or token in a header, a query parameter or the URL path. Your agent declares it with each value as a Secret; you paste the values after deploy.

Inside SegmentStream

Connected once, used everywhere.

Connections are declared in your repository and authorised in the console. The credentials stay with the platform; apps, pipelines, workflows and the agent use them under the same roles.

The console's connections page: Resend, Xero, Stripe, Supabase, LinkedIn and Telegram connections, each connected, with the key it is declared under in code — Connections declared in code and authorised here. The credentials stay with the platform, never in the repository.

What the connection reaches

One to eight values per connection, each a Secret
Headers, query parameters or a URL path segment
Responses that echo a value are refused

Status: Built into the pipeline SDK
Connection class: ApiKeyConnection
Credential: API key or token

Connect Any API with a key

Three steps, the same for every connection. The credential goes to the platform, never into the repository or pipeline code.

Declare it in connections/connections.py

connections/connections.py

from segmentstream.connections import ApiKeyConnection, Bearer, Secret connections = (    ApiKeyConnection(        key="billing",        name="Billing",        provider="billing",        headers={"Authorization": Bearer(Secret(label="API key"))},        apis={"v1": "https://api.billing.example.com/v1/"},    ),)

2
Deploy
```
$ segmentstream deploy
```
3
Connect
Paste the values (from the provider's settings) into the connection in the console, or configure it from the terminal with a hidden prompt. API-key connections need no authorisation step: once the value is set, the connection is connected.
```
$ segmentstream connection configure billing
```

Use it

Code asks for the connection by its key. The platform adds the credential on the way out.

pipeline/ingestion/…

import segmentstream as s with s.get_connection("billing").get_http_client() as client:    response = client.get("/invoices", params={"limit": 100})    response.raise_for_status()

Or ask your agent

“Add our billing provider's API with an API key and load invoices daily.”
