Your agents need context
Stop paying for missing context, unreadable docs, and invisible spend.

No spec, no context, so agents start guessing
An agent working alone in a small project barely needs context. Drop it into a real codebase, and what it needs is scattered across other repos, other teammates, contracts nobody wrote down. Without a map, it doesn’t fail. It guesses, and every guess is tokens spent.
That’s what Postman’s Context Graph fixes: one queryable map of every spec, collection, and connected repo, so the agent asks what’s real before it writes a line, instead of grepping around and hoping. Skip the guesswork, skip the retries, get the right answer on the first try.
Traditional docs burn tokens unnecessarily
Most documentation is still written for humans, not agents, so an agent has to parse dense HTML pages just to answer questions a real spec would answer directly. When you browse docs like this with agents (like Claude, ChatGPT, or Cursor), it costs 5.6× more tokens than a spec, with lower accuracy.
Fern builds docs and SDKs straight from the spec, so they stay accurate and ship as structured, agent-readable text instead of HTML pages built for people to click through.
Fragmented AI access and visibility
AI costs grow quickly, but most organizations lack real-time visibility into who is consuming tokens, which LLMs are driving spend, and where budgets are being exceeded.
Fabric Gateway meters every token in real time across teams, users, LLMs, and routes, so you can set budgets, enforce limits, and catch overruns before the invoice does.
You don't know which agents are worth the spend
Run more than a handful of agents, and cost tracking breaks down fast. A $10 task and a $10,000 one show up identically on the invoice, so nobody can say which agents are earning their keep and which are quietly burning budget on jobs a cheaper model could’ve handled.
Astro AI tracks real-time spend and performance by agent, model, and team in one registry, so you can see exactly which agents are earning their keep and double down there.
