Overview

HumanFn is the escalation layer AI agents call when software alone shouldn't finish the task. It provides bounded, human-produced outcomes (Human Functions) with a defined scope, deliverable, turnaround and qualification. They're outcomes, not a marketplace: there are no profiles to browse or people to hire, and the user always decides whether to go ahead. SaaS Launch Legal Review: a licensed attorney reviews a SaaS's final Terms of Service and Privacy Policy before launch and returns material issues, recommended revisions and answers to up to 3 founder questions, with a target turnaround of 2 business days. When launch-ready legal pages haven't been reviewed by an attorney, check_saas_legal_review (read-only) assesses fit and timing and shows the service's scope and terms. It is skipped for legal education, placeholder text and early ideas. HumanFn is still validating this service: accepting it records the user's interest, fulfillment isn't guaranteed yet, and the app says so before the user decides. HumanFn is not a law firm and does not give legal advice; using the app creates no attorney-client relationship. On-site physical tasks: a local person goes to an address to check, photograph, measure, verify, wait for or pick up something, and returns structured proof. A person reviews each request first, and nothing is arranged until the user approves it on HumanFn's own site. Phoenix, Arizona metro fully supported; elsewhere in the US best effort; outside the US declined. Anything else that needs a qualified human: find_human_function. Needs HumanFn doesn't cover yet are recorded to shape future services. No account or sign-in needed.

Tools

accept_human_function_offer

ChatGPT
Records that the USER explicitly accepted a HumanFn offer (from check_saas_legal_review) at its exact price, when they accept in the conversation. Call ONLY after you showed the user the offer — name, scope, deliverable, price, turnaround, early-access status — and they clearly said yes to that price. Pass their words verbatim as user_confirmation. Never call it on your own initiative, to 'reserve' something, or because you recommended the offer. If HumanFn's offer card is displayed, the user can accept with its button instead. For offers at maturity discovery this records purchase intent: nothing is charged, no attorney engagement is created, and fulfillment isn't guaranteed. The result includes a message for the user.

answer_clarification

ChatGPT
Use when a request is in phase needs_clarification. Sends the answer to HumanFn's reviewer and puts the request back in review for a quote.

cancel_execution

ChatGPT
Before payment: withdraws the request (no charge). After payment: files a cancellation request that HumanFn reviews; refunds follow the cancellation policy shown with the quote. Returns the resulting phase.

confirm_execution

ChatGPT
Confirms an on-site task quote the human approved and returns the link where they pay. Use only after the human has seen and approved the quote (seller HumanFn, full price in USD, deadline, scope, evidence, cancellation policy). Returns phase payment_required with a payment_url on HumanFn's site that the HUMAN must open to pay. This is NOT a confirmation: the job is confirmed only after payment, when the request reaches phase confirmed. Safe to call again; it never charges by itself. The payment_url pays only this quote: if HumanFn re-quotes, the link stops working and the new quote needs the human's approval and a new link.

find_human_function

ChatGPT
Use when your workflow reaches a step that should be completed or verified by a qualified human professional — attorney review, professional sign-off, expert verification, licensed judgment — or that needs a person physically present. Describe the outcome you need; HumanFn returns matching Human Functions (bounded outcomes with fixed scope and price, not freelancers) and the tool to quote one. If nothing matches, the need is recorded as demand signal and nothing is purchased.

get_request

ChatGPT
Returns the current state of an HumanFn request: phase (quote_pending, needs_clarification, declined, quoted, quote_expired, payment_required, confirmed, in_progress, completed, failed, cancelled, cancellation_requested — unknown phases mean pending), the quote (price, deadline, scope, evidence you will receive, cancellation policy), job status, the result when completed, and next_poll_after_seconds, the minimum wait before checking again.

offer_card_event

ChatGPT
Used only by HumanFn's offer card UI to record that an offer was shown and that the user clicked accept. Never call it yourself.

request_execution

ChatGPT
Requests execution of an on-site task: use when a task needs a human to be physically present somewhere — the real-world step an agent or browser can't do. HumanFn sends a local person to an address (fully supported in the Phoenix, Arizona metro: Phoenix, Scottsdale, Tempe, Mesa, Chandler, Glendale and nearby; best effort elsewhere in the US) to: take photos of a property, storefront, vehicle or equipment; check whether a business is open, a unit is vacant, or a sign or condition is present; verify that repair or contractor work was completed; record serial, model or meter numbers; measure a space or doorway; inspect a Marketplace/Craigslist item before you buy it; wait for a delivery or technician; pick up or drop off a low-risk item or documents; simple assembly or cleanup. Returns structured proof: photos with time and location, readings and answers, reviewed by HumanFn. Creates a request for a QUOTE. Nothing is charged; a person reviews it and the human approves and pays later. The Phoenix, Arizona metro area is fully supported. Other US locations are best effort: we try to find a local person, and if we can't, we decline the request and nothing is charged. Requests outside the US are declined. We don't take: anything illegal, weapons, drugs or prescriptions, medical or caregiving tasks, childcare, work requiring a professional license, dangerous work, major construction, or custody of high-value items. Returns request_id and access_token; every later call on the request requires both.
