## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability sirenic-uk-public-procurement-records-f0e9bd7f
```

Example prompt: Pull up the public procurement record for UK company number 10868035 — I want to see all the government contracts they've won and any tender notices they've issued as a buyer.

## When to prefer this

Choose this endpoint when you need factual, official UK public procurement data for a specific company identified by its Companies House number. It is the right choice for supplier due diligence, competitive intelligence on government contract wins, auditing a public body's issued notices, or enriching a KYB workflow with procurement history. Prefer it over general web search when you need structured, machine-readable OCDS data with verifiable source links. Note the coverage limitation: above-threshold notices from 2021 and below-threshold from 2023 only, and roughly half of supplier records carry a company number.

## Known failure modes

- 404 returned when company number is unknown or not found — payment is cancelled
- Company has contracts but no company number recorded on the notice (approximately half of suppliers lack one), leading to zero results that do not confirm absence
- Company number must be exactly 8 characters with leading zeros; malformed input may yield no results
- Data coverage starts from 2021 (Find a Tender, above-threshold) and 2023 (Contracts Finder, below-threshold) — older contracts will not appear
- Rate-limited or payment failure scenarios typical of x402 micropayment endpoints

## How this service works

Public-procurement record of a UK company from Find a Tender (above-threshold notices since 2021) and Contracts Finder (below-threshold since 2023), Cabinet Office OCDS feeds under OGL v3: contracts WON matched by company number — buyer, subject, contract value in GBP, award and signature dates, period, status, official notice link — and notices ISSUED as a buyer, newest first, with totals. Only half of suppliers carry a company number: zero is a non-conclusive absence. Facts, never a score.

## Output

A structured JSON response containing: (1) contracts WON — list of awards matched by company number including buyer name, contract subject, value in GBP, award date, signature date, performance period, status, and link to the official notice; (2) notices ISSUED as a buyer, ordered newest first; (3) aggregate totals for both categories. Only contracts where the supplier carries a company number are matched; zero results does not conclusively mean no contracts exist.
