## 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 school-signals-buyer-brief-api-pay-with-usdc-on-base-f83e2e5c
```

Example prompt: Pull the School Signals buyer brief for the trust with GIAS UID 15710 — I want to see their live tenders, upcoming renewals, and who the incumbent suppliers are so I can plan our edtech sales outreach.

## When to prefer this

Use this endpoint when you need structured UK school or trust-level edtech procurement intelligence — specifically contract renewal timing, incumbent suppliers, and live tenders — for a known school (by URN), trust (by GIAS group UID), or org slug. It is the right choice for edtech sales teams, market researchers, and procurement analysts who want actionable buying signals without building their own pipeline from Contracts Finder and GIAS. Prefer this over raw DfE data sources when you need a pre-processed, pay-per-query summary with no account setup.

## Known failure modes

- Invalid or unrecognised buyer identifier returns an error or empty result
- Payment not processed (x402 protocol failure) blocks access to data
- URN or trust UID does not exist in the DfE GIAS dataset
- Coverage gaps: many school purchases are never published on Contracts Finder or Find a Tender, so results may be incomplete
- Snapshot data may be up to days old; real-time tender status not guaranteed
- Query parameter 'buyer' missing returns a validation error

## How this service works

Buy UK school edtech renewal data (queries from $0.03, England snapshot 295 USDC) and the DfE AI safety evidence toolkit (149 USDC) with canonical USDC on Base. Automatic delivery, no account.

## Output

Returns a structured JSON object with: buyer identity (name, region, trust type, GIAS and Companies House URLs, school count, pupil numbers), a summary of live tenders, published contracts, contracts with named incumbents, and renewals due in the next 12 months, plus a 'caps' object showing counts of changes, tenders, upcoming renewals, contracts, candidates, and incumbents. Includes data provenance (snapshot date, OGL licence attribution, source URLs) and a coverage warning noting partial visibility of school purchasing activity.
