Plain-language engineering question over the whole platform, answered by platform rules without any external model: selection by requirements, values of a property across a class, companies by capability and country, launch windows, term definitions. Returns a short answer plus data blocks (candidates A/B/C, values, companies, launches). Use when the question does not map cleanly onto one structured tool.

}Engineering budget for a component stack: pass product ids (from the other tools) and your bus voltage, get total mass, total steady-state power, per-item data interfaces, voltage-compatibility verdicts and an honest list of what could NOT be counted because the vendor does not publish it. Use it to assemble and sanity-check a subsystem, e.g. 3-4 reaction wheels for an ADCS.

}Assemble a whole spacecraft bus from a plain-language task: the service plans the subsystems, matches every item deterministically against the stated requirements, computes the mass/power budget and writes an evidence-bound rationale. Pass fixed = product ids you have already chosen (from match_components or get_datasheet_digest): they stay in their subsystems, are checked against the requirements (selected.fixed, fixed_verdict, fixed_fails) and the rest is assembled around them. LLM-backed and rate-limited (6/min, 30/h anonymous).

}Alternatives / second sources / replacements for ONE product: requirements are derived from its own published values (key fields of its class — higher-is-better at least 80 %, lower-is-better at most 120 %, same interface, band or type) and its class is searched without it. Returns the derived requirements, fields not compared, and groups A (meets all), B (fails one), C (data missing). Use when a part has a long lead time, is discontinued or export-restricted. Equal figures do not make a drop-in replacement — interfaces must be confirmed with the manufacturer.

For vendors: what to publish; for buyers: what to ask.

Returns companies with their matching products, and how many more companies may fit because the decisive value is not published.

}Facts machine-read from a product datasheet, by section (identity, performance, electrical, interfaces, mechanical, thermal, environmental, qualification, lifetime, options, compliance, commercial). Each fact carries unit, condition, the page and a verbatim quote it was verified against (confidence L0) plus a link into the PDF. Use it for what the typed layer does not hold: connectors, protocols, survival temperature, vibration, radiation, heritage, options, export control, lead time. Pass product_id from match_components or a product name.

}Reverse search over a typed spec layer: pass a category and engineering requirements, get every catalogued item grouped as A (meets all stated requirements), B (fails a named requirement, both figures quoted) or C (could fit, data missing). Verdicts cite the datasheet page. Omit parameters you do not care about. Categories: reaction-wheels, star-trackers, obc-computers, batteries, radios, solar-panels, propulsion, sun-sensors, magnetometers, magnetorquers, imus-gyros, gnss-receivers, eps, deployers, thermal, antennas, sdr-modems, cameras, structures, platforms, ground-stations, sadm, tanks-valves, separation-systems, pointing-mechanisms, test-facilities (environmental test labs — items are companies: test, shaker_min_kn, tvac_min_m, specimen_min_kg, emc_min_m). The answer is compact: group A in full (up to 25), groups B and C — the first 10 with the reason, plus counts and the fields most often unpublished in C; page with group and offset.

| group | string | page through one group only — use with offset from paging.next |
| limit | integer | items of groups B and C to return (default 10, max 50); group A comes in full up to 25 |
One fact key across a whole category: which products state it in their datasheets and what value — e.g. connector, data_interface, protocol, survival_temperature, tid_tolerance, flight_heritage, trl, export_control, lead_time, price, design_life. One row per product with page and quote. Reports coverage (how many products of the category have a digested datasheet).
