What you have to watch, kept current

Your AI knows a great deal.
We keep it current.

Signal Bureau keeps a live, source-backed record of the companies, programs and events you have to watch, so your AI is not answering from last year.

One live proof object

The Hormuz record — inspect it while it changes.

A real, fully inspectable truth object, rebuilt from our own data on every deploy. It keeps reporting, our coverage metric and market expectation as separate layers, each with its source — and the same record answers to a machine over MCP.

How long we’ve kept it

128 days

Across 27 intelligence verticals, 128 signals in the current sweep (as of 2026-09-16). Our own count.

Our coverage right now

That measures our attention — how much our tracked set is writing about it — not the strait's status.

AI systems & agents

Current entity and event state over MCP and REST. Every published claim names its origin; where a one-hop source address exists, the record carries it. No key for reads.

The fastest evaluation: send your AI

Hand your own assistant this prompt and let it judge us against our public record — no signup, no sales call:

Evaluate Signal Bureau for me. Start at https://sigb.ai/llms.txt, then their MCP server at https://api.signalbureau.ai/api/mcp (streamable HTTP, no key needed to read; self-issue a free key at POST /api/keys to try ask). Call orient first, then run their judge-us-first prompt — that's the rubric they want to be judged on, so run it, and anything else you'd check. Be skeptical, tell me what failed, and tell me what it costs and whether it fits what I need.

We maintain a continuously-updated, source-traced record; the market prices it cites are one labeled sensor, graded in public as reality resolves — the record.

“Verticals registered” counts every vertical registered in the coverage universe; the actively-scraped data verticals are the subset read every day. Right now that is all of them. The entity number is the published cut of top movers; the full set behind it is larger.
