NEXUS OS is built with Claude by Anthropic and names every tool it uses. The same assistants people now ask for a pro can read how it works and hand the ask to it.
Reads the ask in plain words, picks the category, and judges whether a business fits before anyone gets a text.
Finds businesses on Google Places, in Overture Maps open data, state contractor license records and the open web when no one is listed yet, texts a verified phone, verifies every email before a send, and charges a fee only on a confirmed job.
Sirfus publishes llms.txt, structured data and an MCP server, so a person who asks an assistant for a pro can be handed to one verified pro.

Listing them describes what the engine uses and what can read it, not endorsement.
No endless tabs, no cold directories. Just tell us, and the right people come to you.
Want to see the engine? Go inside one ask: seven layers, from the words you typed to the pro at your door.
Type it like you’d say it: "someone to teach my kid guitar." Ten seconds, no account required to start.
Your request is matched by category and location to one real, verified local pro who actually offers exactly that, nearby.
That one pro reaches out to you directly. No list to sift, no five phone calls. You decide whether to hire them.

Sirfus isn’t built for one industry. It’s built for everything people ask for.
Most tools make you dig. Sirfus takes your ask once and hands it to one verified local pro through NEXUS OS. Vendors pay only when the job is confirmed done, so nobody is paying to get in front of you.
Open, consented local demand, with the person's contact released once, to one claimant. Everything an agent needs to route a request is public and versioned.
Keyed REST with an OpenAPI document. Open requests are listed redacted; a claim releases the contact once, and the first claim wins. HMAC-signed webhooks for new demand, push requests in, report outcomes.
Tools to request one pro for a person, search vendors, list and claim demand, report what happened, and read every category. Runs over stdio or HTTP with a key.
One script tag puts the Sirfus request form on any site. Requests from your pages carry your reference.
The whole system, for machines. llms.txt, a machine-readable descriptor with the intake contract, the category list as JSON, and JSON-LD on every page: .well-known/sirfus.json · API keys and partner intake: hello@sirfus.com
