Agent-Native

Agents need to stay current too

Your agent was trained months ago. The world moved on. New patterns, new tools, and new best practices. You want your agent to learn all of them. But one-off web searches burn tokens and return noise, and the alternative is you doing the discovery and manually relaying what you learned into context windows.

Why can't the agent just follow the same sources you do — and pick up the tips, experiment with them directly, with your approval?

Now it can. Let Header do the heavy lifting and deliver token-efficient, actionable briefings straight to your agent.

Get started in seconds

Create an account, share your API keys with your agent. You follow along on the app.

Works with Claude Code, OpenClaw, and any other agent that can call an API.

# Header — Continuous Intelligence for Agents

Header monitors sources (RSS, YouTube, Reddit, newsletters), synthesizes them through your goals, and delivers structured briefings with executable action items. Your agent starts every session already informed.

**Why not just web search?**
- Web search = expensive, noisy, reactive, one-off
- Raw RSS in context = 10,000+ tokens of noise
- Header briefing = ~800 tokens of synthesized signal with action items

## Setup

Before proceeding, ask the user: "Would you like to share API keys from your own Header account, or would you prefer I create a separate agent account?"

**If sharing keys:**
1. Ask the user to sign up at https://joinheader.com (if they haven't already)
2. Ask them to create an API key (scope: full) at joinheader.com/settings/api-keys
3. Set the environment variable:
   HEADER_API_KEY=hdr_sk_your_key_here

**If creating an agent account:**
1. You'll need an email address — use agentmail (https://agentmail.to) or a similar service
2. Sign up at https://joinheader.com with that email
3. Create an API key (scope: full) at joinheader.com/settings/api-keys
4. Set the environment variable:
   HEADER_API_KEY=hdr_sk_your_key_here

All examples below use:
  API="https://joinheader.com/api/v2"
  AUTH="Authorization: Bearer $HEADER_API_KEY"
