## Tools (as reported by the server, not verified)

- `ask\_astranl`: Turn a real-world task or question into a routing decision: whether AstraNL can help, which one tool to call, what to supply, what can and cannot be verified. No commitment, nothing created, no key. Also answers whether a physical task is feasible in the Netherlands.
- `check\_counterparty\_nl`: Check a Dutch or EU counterparty against official sources before your own next step, such as onboarding a supplier, paying an invoice or signing an order. Give the KvK number, the company name and the EU VAT number as your document states them. Returns verdicts, not register data: whether the KvK nu
- `record\_counterparty\_check`: Make a result of check\_counterparty\_nl verifiable by others: records its digest in the AstraNL signed public log and returns a reference that a colleague, approver or auditor can check later with verify\_astranl, without trusting AstraNL. Works only for a check AstraNL produced in the last 48 hours.
- `create\_task`: Ask AstraNL to find and coordinate a verified executor for a physical task in the Netherlands. Returns an ingress receipt at once and a case once planning found a path; the client pays the executor directly; AstraNL holds no money.
- `check\_task`: Current state of a task or ingress receipt from create\_task, and who must act next. Returns only what is recorded; infers nothing.
- `get\_evidence`: Machine-checkable evidence for an AstraNL task, action or receipt: the signed log events that mention it, each verified live, with a proof block stating what is verified, what is not, validity, status, limitations and next actions.
- `verify\_astranl`: Verify any AstraNL reference without a key. Returns two separate layers: integrity \(payload hash, Ed25519 signature, Merkle inclusion, recomputed live\) and claim \(what exactly is attested, by whom, from which source, when, under which method, with which validity limits and current status VALID/EXPIR
- `ground\_astranl`: Get compact, source-linked real-world context for an LLM in ONE read-only call. Searches AstraNL public materials or tender records, or its protocol identity. Use source=public\_tenders for tenders, materials for products; auto keeps domains separate. Returns record update times, fresh/stale/unknown
- `ground\_component`: Ground a machine, robot or industrial automation component in live market reality with ONE read-only call. Give a manufacturer part number and optionally the maker. AstraNL queries its verified distributor connections \(Nexar/Octopart, Mouser, element14/Farnell NL, OEMsecrets\) in parallel, keeps only
- `ground\_citation`: Check one scientific reference before you reuse or cite it, with ONE read-only call. Give a DOI. AstraNL reads the Crossref work record and every Crossref notice that updates it, the OpenAlex retraction flag and the Europe PMC publication types and retraction, erratum and concern links, and returns
- `construction\_summary`: One-call overview of Dutch construction facts: permit publications last 90 days \(national\), lead-time status, number of open public works tenders, latest CBS periods, construction laws taking effect in the next 365 days. Permit kind accuracy is measured, not assumed: manual validation gate B on a 20
- `construction\_permits`: Official permit publications counted per issuing body \(municipality, province, water board\) and kind \(application, granted, refused, ...\) over the last N days \(default 90, max 400\). Permit kind accuracy is measured, not assumed: manual validation gate B on a 200-row sample \(2026-10-05\) gave precisio
- `construction\_leadtimes`: Permit lead times \(application to decision, median and quartiles\) from official pairs. Currently CLOSED: the answer says CLOSED with the reason until validation gate C passes; no lead time is estimated before that. Read-only aggregates: no permit rows, publication identifiers, titles, addresses, poi
- `construction\_tenders`: Open Dutch public works tenders from TenderNed \(announcements with a future closing date\): buyer, CPV, procedure, published and closing date, days left, European flag, TenderNed id and link. Tender names are not returned; open the link for the full notice. Read-only aggregates: no permit rows, publi
- `construction\_laws`: Construction law calendar: dated rules in force or planned \(Omgevingswet, Wkb, EPBD IV, MPG, CPR, ...\), each with its own official or sector source and last-verified date; rows whose planned date passed are flagged needs\_reverify. Read-only aggregates: no permit rows, publication identifiers, titles
- `construction\_economy`: CBS construction economy: build cost input price index, construction bankruptcies, construction vacancy rate \(latest stored period, CBS status Voorlopig/Definitief per row, freshness\) plus CBS indicators \(dwelling permits, establishments, labour\). Provisional figures are revised by CBS. Read-only ag
- `construction\_zones`: Dutch zero-emission and low-emission zones from NDW as published: municipality, zone label, status, start, vehicle categories, transition rules, bbox centre; derived\_ze\_logistics is derived by AstraNL. Source recount \(ids and hashes\) is reported. Read-only aggregates: no permit rows, publication ide
- `construction\_natura`: Natura 2000 sites in the Netherlands from RVO / PDOK: number, site label, protection type, status, site code, bounding box \(lon/lat\). Filter with site. Source recount is reported. Read-only aggregates: no permit rows, publication identifiers, titles, addresses, points or names; permit counts below 5
- `construction\_events`: CloudEvents 1.0 feed of construction signals, oldest first after since\_id: daily permit aggregate cells \(with gate B accuracy\), newly published works tenders \(AAO\), laws coming up. Continue with next\_since\_id. Read-only aggregates: no permit rows, publication identifiers, titles, addresses, points o
- `nl\_municipal\_build\_rules`: Dutch municipal rules for a renovation or building job, with ONE read-only call. Give a municipality, optionally the planned bouwkosten excluding VAT. Returns the 2026 omgevingsvergunning fee, leges, for the technical building activity as the municipality's own regulation sets it, and whether a skip
- `check\_material`: Check one building material in live Dutch store reality with ONE read-only call. Exact identity only: a GTIN with valid check digit, a store variant or the exact partner feed link; plain words return candidates you can check exactly next. Returns every offer of the same trade item with price incl. V
- `check\_estimate\_materials`: Check every material line of an AstraNL estimate case you hold the token of \(from estimate\_case\_create\) against the current offer of the same product: PRICE\_UP or PRICE\_DOWN beyond 5 percent, UNAVAILABLE, NOT\_FOUND\_IN\_CHECKED\_SOURCES, CHEAPER\_SAME\_GTIN at another store, each with source and read tim
- `estimate\_case\_create`: Create a real estimate case through the public router. Reuses the connection X-Agent-Key; requester\_kind is agent. Save case\_id and token securely. language selects human-client output, default nl. Duplicates do not return a token. Processing may be asynchronous.
- `estimate\_case\_status`: Read the exact public case-status JSON using case\_id and its token. Human-client questions and documents retain their language. Deliver an estimate only when release\_state is RELEASED; DONE alone is insufficient.
- `estimate\_case\_answer`: Submit human answers as a map from question ID to text. The public router validates, merges and queues an operator rerun; submission does not itself spawn processing. Requires the case token.
- `estimate\_case\_files`: Upload photos or plans as base64 contents, never local paths or URLs. Requires the case token. Public feature flag, type checks, sanitization and quotas apply: 10 files, 15 MiB each, 60 MiB per case. Upload acceptance does not prove incorporation into an existing estimate.
- `estimate\_case\_video`: Video action=create takes one base64 file up to 250 MiB and reuses the connection agent key. action=status takes intake\_id and its token only. After case creation, use case\_id and case\_token with estimate\_case\_status. Video and case tokens are distinct.
- `estimate\_cost`: Legacy model-based cost figure in EUR, with human-provider and robot-automation comparisons. AstraNL currently has zero recorded real price observations for this service. This tool does not create an estimate case and does not provide a reviewed quotation. For the real case engine use estimate\_case\_
- `search`: Search AstraNL coordination data \(robots registry, service categories, and merchant parts by keyword\). Returns a list of results, each with an id and a short title/snippet, for use with the fetch tool. Read-only. This is the generic discovery entry point expected by agent frameworks.
- `fetch`: Fetch the full record for a single result id returned by search \(robot passport, category detail, or merchant SKU\). id 'context' returns the AstraNL continuation packet: live state, open mandates and recent sessions, the same text as https://astranl.com/api/context.md. Read-only.
