# Tenderline
> UK procurement intelligence. The public platform is a procurement knowledge graph built from official open data, with competition and price context wherever the published record holds enough evidence.

Tenderline is a UK procurement intelligence company. Its public platform normalises, links and enriches official UK procurement data (Find a Tender today; further sources being added) into an evergreen knowledge graph: tenders, planning notices, contracting authorities, awarded suppliers, lots and awards, with the competition context a bid team needs (typical bids per lot, award vs estimate, who wins, contract expiry, similar open opportunities) shown where enough published evidence exists; thin records say so instead of guessing. Structured access for people and AI agents; the counting rules are public at /methodology.

## Querying Search (URL parameters)
Search is a plain GET page; build the URL directly instead of filling the form.
- `https://tenderline.uk/search?q=grounds+maintenance`: keywords over titles, lot titles, buyer names and descriptions; all words must match. Syntax: `"exact phrase"`, `cleaning OR catering`, `software -consultancy`, `govern*`.
- `stage=`: `open` (default: notices that still accept a response: a deadline ahead, or no deadline on a non-planning notice its publisher updated within the last 12 months), `planning` (planned / pre-market notices), `awards`, `contracts`, `all`.
- `cpv=`: CPV code or prefix, 2–8 digits (`72`, `7226`, `72260000`). `region=`: delivery region ITL1 code (`UKI` London, `UKM` Scotland, …).
- `closing=` `2d|7d|14d|30d` · `value=` `lt25k|25k-100k|100k-500k|500k-1m|1m-10m|gt10m` · `smeOnly=true` · `vehicle=` `framework|dps|contract`.
- `sort=` `relevance|published|deadline|expected|newest|value`. Default: relevance with keywords; otherwise newly published (live), tender expected soonest (planning), newest (other tabs).
- A notice id (`ocds-h6vhtk-06e968`) or the short id in our titles (`#06e968`) opens that tender directly. Every tender page has a Markdown twin: append `.md` to its URL.

## Dynamic Purchasing Systems (DPS) & Framework Navigation
- **DPS vs Standard Tenders:** Dynamic Purchasing Systems admit suppliers throughout their published period. Tenderline lists one as open while its published deadline is ahead or, without a deadline, while its publisher keeps the notice updated (within 12 months). In Tenderline markdown and JSON, DPS procedures are explicitly tagged (`commercial_vehicle: "dps"`, `is_dps: true`) and turnover benchmarks reflect individual task-order ceilings rather than notional multi-billion framework aggregates.
- **Contract Expiry Horizons:** Retender Radar (`/retenders`) and buyer profiles list published contracts ending in the coming months where an end date is published; an ending contract is a signal, not a promise that a new tender will be issued.

## Data Model & Markdown Mirror
- [Markdown Mirror Documentation](https://tenderline.uk/llms-full.txt#markdown-mirror): Append `.md` or send HTTP header `Accept: text/markdown` to any tender (`/tenders/{slug}.md`), buyer (`/buyers/{slug}.md`), supplier (`/suppliers/{slug}.md`), CPV sector (`/sectors/{slug}.md`), region (`/regions/{slug}.md`), portal (`/platforms/{slug}.md`), or market insights (`/market-insights.md`) URL for structured, distraction-free markdown.
- [Public Machine API](https://tenderline.uk/api/public/tenders/ocds-h6vhtk-050df9): Query `/api/public/tenders/{ocid}` for official OCDS-linked procurement JSON with lot breakdowns, winner identities, award values, and source provenance.
- **Edge Caching:** `.md` mirrors and public JSON endpoints are cacheable at the edge (`Cache-Control: public, s-maxage=3600..86400`); please reuse cached copies rather than refetching.
