Official government APIs

PSIP connects directly to the official REST APIs published by each procurement portal — Find a Tender, Contracts Finder, Public Contracts Scotland, Sell2Wales and eTendersNI. We do not scrape or mirror third-party sources.

Daily refresh

Our pipeline runs daily, pulling all new and updated notices from each source. Tender status changes (active → closed → awarded) are updated as they appear in the source data.

Deduplication

Contracts that appear on multiple portals (e.g. a Scottish contract appearing on both Find a Tender and PCS Scotland) are deduplicated by source reference ID to avoid double-counting.

Data enrichment

Where available, we enrich tender records with Companies House supplier data, NHS ODS buyer data, and GIAS education establishment data to improve buyer intelligence accuracy.

AI scoring

AI relevance scoring uses Anthropic Claude to evaluate each tender against your specific business profile. Scores are calculated at search time — not cached — so they always reflect your current profile.
