## Tools (as reported by the server, not verified)

- `school\_signals\_search`: Free. Find buyer ids \(school:\<URN\>, trust:\<UID\>, org:\<slug\>\) with counts of published edtech contracts, renewals in the next 12 months, live tenders and trust changes. Use before school\_buyer\_brief.
- `school\_renewals`: Paid $0.03 USDC. Up to 25 published edtech contracts at English schools, trusts and councils ending in a window, with incumbent, value, extensions, estimated re-procurement window and official notice links. Empty results and invalid filters are refused before payment.
- `school\_buyer\_brief`: Paid $0.20 USDC. Hierarchy, published edtech contracts and incumbents, upcoming renewals with estimated windows, live tenders, recent trust changes and official links for one buyer. Unknown, ambiguous \(candidates returned\) or evidence-free buyers are refused before payment.
- `list\_products`: Free. Every product with its price in USDC, route, licence and how to pay \(x402 or plain transfer on Base\).
- `buy\_file\_x402`: Paid 295 USDC \(school-signals-england-snapshot\) or 149 USDC \(dfe-ai-safety-toolkit\) via x402; returns a signed 48-hour download link, the file SHA-256 and an order URL. Without payment returns the x402 terms. If your client caps automatic payments, use create\_transfer\_order instead.
- `create\_transfer\_order`: Free. Creates a 24-hour order with an order-specific exact USDC amount on Base. Send exactly that amount of canonical USDC to the recipient in one transfer, then call check\_transfer\_order with the transaction hash.
- `check\_transfer\_order`: Free. With only order: status \(and a fresh download link once paid\). With tx\_hash: verifies the Base transaction \(canonical USDC, recipient, exact amount, success, time window, 10 confirmations, never used before\) and returns the download link.
