Problem
AI agents quickly become outdated as new tools, patterns, and best practices emerge, forcing developers to perform manual web searches or manually update prompts, which consumes tokens and introduces noise.
Solution
Header offers an API that delivers token‑efficient, structured JSON briefings on user‑defined topics directly to agents. Users create Topics that aggregate trusted sources (RSS feeds, YouTube channels, newsletters, Reddit, etc.) and define Goals with natural‑language relevance criteria. Header continuously ingests content, filters it according to the Goals, and synthesizes concise briefings using LLMs. Agents can pull the latest briefing via a simple endpoint and stay aligned with the most recent information without additional searches or manual curation. The service integrates with Claude Code, OpenClaw, and any API‑capable AI, enabling seamless updates to deployed agents.
Target Audience
Primary customers are developers and teams building autonomous AI agents or LLM‑powered applications that need up‑to‑date domain knowledge, as well as knowledge workers who want automated, curated briefings on specific topics.
