ChilledSites

ChilledSites is a UK-built AI website builder (by p0stman) that generates, edits and deploys complete small-business websites from a text prompt, with hosting, custom domains, contact forms, an AI chatbot, reviews and analytics included from GBP 9 a month. It is unusually agent-native for its size: a REST API at api.chilledsites.com (websites CRUD, deploy, image/video/ad generation, token balance) behind a two-header API key, an A2A agent card at /.well-known/agent-card.json, a hosted MCP endpoint plus the @chilledsites/mcp-server npm package (16 tools), agent self-signup with no human step, and a 402 token-billing flow that emails the account owner a payment link so an agent can resume after a human pays. Discovery files (llms.txt, context.md, agents.md, mcp.json, agent-meta.json) are published at the domain root. No OpenAPI, status page, changelog or deprecation policy is published.

ChilledSites is listed with 1 API on the APIs.io network. Tagged areas include Company, Website Builder, Artificial Intelligence, No-Code, and Web Hosting.

ChilledSites’ developer surface includes documentation, API reference, getting-started guide, engineering blog, pricing, signup flow, authentication, and 20 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) 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.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.
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/chilledsites-com: open an issue to ask a question, or submit a pull request to add artifacts.
