# Superfeedr PubSubHubbub API

Superfeedr provides a real-time feed API based on the PubSubHubbub protocol. Subscribe to RSS/Atom feeds and receive real-time notifications when content is updated. The API exposes 2 endpoints secured with basic authentication.

## For AI agents

Programmatically subscribe or unsubscribe from a feed, list subscriptions, retrieve feed entries, or replay notifications. Covers 2 operations with basic authentication.

## Scope

Does not handle payments, crm, or developer tools - use for communications only.

## Capabilities

- Subscribe or unsubscribe from a feed
- List subscriptions, retrieve feed entries, or replay notifications
- Integrate Superfeedr PubSubHubbub API into automated workflows
- Query and filter Superfeedr PubSubHubbub API records by parameters
- Monitor Superfeedr PubSubHubbub API operational status and events

## Use cases

### Communications Operations

Use the Superfeedr PubSubHubbub API to perform communications operations programmatically. The API provides 2 endpoints covering core functionality including subscribe or unsubscribe from a feed, list subscriptions, retrieve feed entries, or replay notifications.

Example prompt: Call POST / to subscribe or unsubscribe from a feed

### Data Retrieval and Monitoring

Query Superfeedr PubSubHubbub API resources on a schedule to track changes, generate alerts, or feed downstream dashboards. Agents poll relevant endpoints, compare against previous state, and trigger actions when thresholds are crossed.

Example prompt: Poll the primary Superfeedr PubSubHubbub API endpoint, compare response to last known state, and alert if changed

### AI Agent Integration via Jentic

AI agents discover and call Superfeedr PubSubHubbub API endpoints through Jentic without managing credentials directly. An agent searches for the required operation by intent, receives the matching endpoint schema, and executes the call with Jentic-managed authentication. This eliminates the need to read API documentation or handle basic tokens manually.

Example prompt: Search Jentic for 'subscribe or unsubscribe from a feed', load the operation schema, and execute with Jentic-managed credentials

## Key endpoints

| Method | Path | Description |
| --- | --- | --- |
| POST | `/` | Subscribe or unsubscribe from a feed |
| GET | `/` | List subscriptions, retrieve feed entries, or replay notifications |

## Why Jentic

- **Setup:** Wiring the Superfeedr PubSubHubbub API by hand means handling HTTP basic auth with your login and API token, choosing between the push and stream hosts, and managing retries yourself. Through Jentic you install once, import the Superfeedr PubSubHubbub API from the API Directory, store the basic credentials once, and your agent calls it.
- **Permission scoping:** The subscribe and unsubscribe actions carry the feed topic in the request body rather than as a URL path id, so scope the agent to the operations it needs, such as subscribing to a feed. Unsubscribing is only in reach if you include it in the allowed set.
- **Credential handling:** Your Superfeedr PubSubHubbub API basic credentials are stored once, encrypted, by your own Jentic One instance and injected at execution time. They never enter the agent's prompt, logs, or context.
- **Discovery method:** Agents search Jentic by intent such as 'subscribe to a feed' or 'unsubscribe from a feed', and Jentic returns the matching Superfeedr PubSubHubbub API operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

## FAQ

### What authentication does the Superfeedr PubSubHubbub API use?

The Superfeedr PubSubHubbub API uses HTTP Basic authentication with username and password. Through Jentic, these credentials are stored encrypted in your Jentic One instance and injected at execution time, so raw secrets never enter the agent context.

### Can I subscribe or unsubscribe from a feed with the Superfeedr PubSubHubbub API?

Yes. Use the POST / endpoint. The API returns structured JSON responses that agents can parse and act on directly.

### What are the rate limits for the Superfeedr PubSubHubbub API?

Rate limits are not specified in the OpenAPI spec. Check the vendor documentation for current limits. Through Jentic, rate limiting is handled automatically with retry logic built into the execution layer.

### How do I subscribe or unsubscribe from a feed through Jentic?

Install the Jentic SDK with pip install jentic, authenticate through Jentic One, the self-hosted execution layer, then search for 'subscribe or unsubscribe from a feed'. Jentic returns the matching Superfeedr PubSubHubbub API operation with its input schema. Load the schema and execute the call - credentials are injected automatically.

### How many endpoints does the Superfeedr PubSubHubbub API have?

The Superfeedr PubSubHubbub API exposes 2 endpoints for communications operations.

### Can I limit what my agent is allowed to do with the Superfeedr PubSubHubbub API?

Yes. Because you run Jentic One yourself, your own rules decide which Superfeedr operations and credentials the agent may use, so you allow only the calls it needs. The subscribe and unsubscribe actions both carry the feed topic in the request body rather than as a URL path id, so you scope the agent to a specific operation such as subscribing to a feed. Unsubscribing stays out of reach unless you add it to the allowed set.
