Stotles

Stotles is a B2G (business-to-government) public sector procurement and sales intelligence platform for the UK and Ireland. It aggregates procurement notices, contract awards, framework agreements, buyer spend history, and verified decision-maker contacts from public sources such as Find a Tender, Contracts Finder, Digital Marketplace, TED, and Public Contracts Scotland, then layers tender discovery, market intelligence, AI-assisted bid qualification (Bid Studio), account targeting (Sales Studio), and pipeline management on top so suppliers can find, qualify, and win government contracts. Delivered as a SaaS web application at app.stotles.com, and — since 2026 — as a programmable surface: the Stotles Public API is a documented OpenAPI 3.1.0 REST service at api.stotles.com/v1 covering notices, buyers, suppliers and framework agreements, alongside a hosted Model Context Protocol server at api.stotles.com/mcp that brings the same market data into AI chat tools and agents. Both authenticate with a static x-api-key header; keys are issued by a Customer Success Manager rather than self-serve, and MCP access is in beta behind a waitlist.

Stotles publishes 4 APIs on the APIs.io network, including Buyers API, Frameworks API, Notices API, and 1 more. Tagged areas include Company, Procurement, Public Sector, Government, and Tenders.

Stotles’ developer surface includes documentation, support, getting-started guide, signup flow, pricing, engineering blog, and 17 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Government & Public Sector regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/stotles: open an issue to ask a question, or submit a pull request to add artifacts.

    Described by Stotles as letting teams "explore the market in natural language and pull the insights they need without
    leaving their tools". In beta behind a public waitlist; tools/list is auth-gated, so the live tool schemas require an
    issued key.
