## Introduction Use the Numeno Article Recommender API to receive a curated selection of articles from across the web. See below for the steps to creating a Feed, as well as an introduction to the top-level concepts making up the Article Recommender API. ## Steps to creating a Feed 1. Create a Feed - [`/feeds`](create-feed) 2. Create a number of Stream queries associated with the Feed - [`/feeds/:feedId/streams`](create-stream) 3. Pull from the Feed as the Feed refreshes - [`/feeds/:feedId/articles`](get-articles-in-feed) 4. Use those Article IDs to look up metadata for the Articles -[`/articles/:id`](get-article-by-id) 5. Visit the Article links and render to your server DB or client app. ## Sources, Articles and Topics A **Source** is a place where Articles come from, typically a website, a blog, or a knowledgebase endpoint. Sources can be queried for activity via the [`/sources`](get-sources) endpoint. Beyond the Sources Numeno regaularly indexes, additional Sources can be associated with Stream queries, and Sources can be `allowlist`/`denylist`'d. **Articles** are the documents produced by Sources, typically pages from a blogpost or website, articles from a news source, or posts from a social platform or company intranet. See the [`/articles`](search-articles) endpoint. **Topics** - Numeno has millions of Topics that it associates with Articles when they are sourced. Topics are used in Stream queries, which themselves are composed to create Feeds. Get topics via the [`/topics`](get-topics) endpoint. ## Feeds **A Feed is a collection of Streams.** Feeds are configured to refresh on a regular schedule. No new Articles are published to a Feed except when it's refreshed. Feeds can be refreshed manually if the API Key Scopes allow. You can ask for Articles chronologically or by decreasing score. You can also limit Articles to a date-range, meaning that you can produce Feeds from historical content. Interact with Feeds via the [`/feeds`](create-feed) endpoint. ## Streams Think of a **Stream** as a search query with a "volume control knob". It's a collection of Topics that you're interested and a collection of Sources you'd explicitly like to include or exclude. Streams are associated with a Feed, and a collection of Streams produce the sequence of Articles that appear when a Feed is refreshed. The "volume control knob" on a Stream is a way to decide how many of the search results from the Stream query are included in the Feed. Our searches are "soft", and with a such a rich `Article x Topic` space to draw on, the "volume control" allows you to put a cuttoff on what you'd like included. Streams are a nested resource of `/feeds` - get started by explorting [`/feeds/:feedId/streams`](create-stream).

RevKeen is a fintech-grade API for payments, subscriptions, invoices, and billing. The canonical production MCP server is available at `https://mcp.revkeen.com/mcp`. **API Version:** `2026-05-01` — Pin with the `RevKeen-Version` header. **Quick Links:** [Full Documentation](https://docs.revkeen.com) | [Authentication](https://docs.revkeen.com/authentication) | [OAuth](https://docs.revkeen.com/oauth) | [SDKs](https://docs.revkeen.com/sdks) | [Webhooks](#webhooks) | [MCP Guide](https://docs.revkeen.com/mcp) ## Authentication Two authentication methods are supported: ### API Keys (recommended for server-to-server REST API integrations) Send your API key in the `x-api-key` header. Get keys from the [Dashboard](https://app.revkeen.com/settings/api-keys). Use `rk_sandbox_*` for test mode and `rk_live_*` for production. ### OAuth 2.1 (recommended for MCP and third-party integrations) Use OAuth 2.1 with PKCE for authorization code flow or client credentials for server-to-server. Tokens are sent via `Authorization: Bearer rk_oauth_*`. See the [OAuth guide](https://docs.revkeen.com/oauth) for setup. - **Authorization Code + PKCE** — user-facing integrations, MCP hosts - **Client Credentials** — server-to-server, automated workflows - **Dynamic Client Registration** — MCP hosts that auto-register ## MCP Integration RevKeen's canonical production MCP server is `https://mcp.revkeen.com/mcp` using Streamable HTTP and OAuth 2.1 bearer tokens. - **Customer launch surface** — read-first customer v1 tools with least-privilege scopes - **Host setup guide** — see the [MCP guide](https://docs.revkeen.com/mcp) for ChatGPT, Claude, and compatible MCP hosts ## API Key Scopes Scopes follow `{resource}:{action}` format (e.g., `invoices:read`, `customers:*`).
