Tools as reported by the server

• verify_document
  Forensically inspect a document (PDF or image) for authenticity: tampering signs, AI-generation indicators, arithmetic reconciliation (financial docs), and provenance. USE THIS WHEN someone shares a payslip, bank statement, invoice, receipt, ID, certificate, or contract and asks: is this genuine / r
• check_document
  Cheap cache-check: has this exact document already been inspected? Hash the file yourself (sha256, lowercase hex) and call this before verify_document to skip a redundant (paid) inspection. Returns {cached, warrant_id, permalink}.
• get_warrant
  Retrieve a stored warrant by id (e.g. 'warrant_<hex>') — the full bundle as JSON, or a human-readable Markdown report when as_markdown=True. USE THIS WHEN you have a warrant_id from an earlier verify_document / check_document call and need the FULL evidence — every signal that fired, per-page findin
• submit_feedback
  Record thumbs up/down on a warrant's rating (the engine's precision-flywheel label source). verdict must be 'up' or 'down'; note is optional free text. USE THIS WHEN the ground truth became known after a verify_document call — e.g. the document was later confirmed genuine or fraudulent — so the engi
• extract_fields
  Extract structured FIELDS from a document (PDF or image) with a vision model. USE THIS WHEN you need specific values OUT of a document — a payslip's gross/net, an invoice's total/ABN, a form's checkboxes, a table's cells — rather than a yes/no about the document. (For "is this genuine?" use verify_d
• verify_identity
  Run an Australian identity check over a SET of identity documents. A vision model reads each document (which ID it is, which fields it shows — name/photo/address/signature — and its issue date); a deterministic engine then tallies them against a scheme and reports whether identity is established, an
• check_pack
  Check whether a SET of documents satisfies a checklist — completeness, cheaply. USE THIS WHEN you have an application / onboarding pack and need "do we have the required documents, and what's still missing?" Each document is CLASSIFIED (one cheap page-1 read — never full field extraction or multi-pa
• screen_adverse_media
  Screen a person or organisation for ADVERSE MEDIA and SANCTIONS exposure (KYC/AML). PEP lists are not screened: `sanctions.flags.pep` is always false and `sanctions.note` says so. USE THIS WHEN onboarding or due-diligence asks: does this subject appear in negative news (fraud, money laundering, brib
• detect_ai_text
  Estimate the PROBABILITY that a document's text was AI-GENERATED (LLM-written prose). USE THIS WHEN someone shares prose — an essay, cover letter, article, review, application, or report (or a link to one) — and asks: did an AI / ChatGPT write this? is this human-written? detect AI text. Provide the
• verify_references
  Fact-check a document's REFERENCES and CLAIMS — built for AI-generated reports whose citations must be checked before they're trusted. USE THIS WHEN someone shares a report, article, whitepaper, or deep-research export (or a link to one) and asks: is this accurate / legit? are these citations real?
• check_source_overlap
  Check whether text OVERLAPS text published on the public web — a plagiarism-style check: does this text appear elsewhere? was this copied? find the source of this text. Provide the document ONE way: `text` (pasted prose), `url` (a public http(s) link — fetched server-side; that page and its host are
• find_tenders
  Search open tenders across Australia; New Zealand rows only when you ask for them (jurisdiction=NZ). FREE, within the weekly cap. USE THIS WHEN someone asks what public-sector work is open: "any council drainage tenders in Victoria", "what's closing this month in NSW", "show me federal IT opportunit
• match_tenders
  Rank open tenders against what a company actually does. Free, inside the weekly cap. USE THIS WHEN someone asks which opportunities suit a specific business: "what could we bid for", "is there anything for a civil contractor in Victoria", "find work for acme.com.au". Give `company_url` — a plain dom
• tender_sources
  Every source we search, what it is allowed to do, and what the last run returned. FREE. USE THIS WHEN someone asks where the data comes from, whether a particular portal is covered, or why a search came back empty. It is the honesty surface: it names sources behind login walls, sources whose robots.
• buyer_awards
  What a buyer has awarded, what is ending, and what they plan. FREE. USE THIS WHEN someone asks about a specific buyer before a bid: "who holds Transport for NSW's work", "what is ending soon at Queensland Health", "what does this agency usually pay". Give `buyer` (the organisation name as published)
• find_signals
  Signals: what may be tendered before it is. FREE. USE THIS WHEN someone asks what is coming: "which contracts in Queensland end in the next six months", "what is planned for ICT next quarter", "what is expiring for this buyer". `kind` is one of contract_expiry (a contract ending, with its incumbent)
