Context

Context (ctxt.io) is a no-signup, rich-text pastebin for sharing web pages, code snippets and formatted text through auto-expiring links, with lifetimes from 5 minutes to 30 days (Context Pro extends pastes to 30 days and allows deletion). It offers Chrome and Firefox browser extensions and a hosted remote Model Context Protocol (MCP) server at https://ctxt.io/mcp (Streamable HTTP, no account or API key) that lets AI agents such as Claude Code, Codex, Cursor and VS Code turn diffs, logs, snippets and docs into share links and read them back; the client-side plugins and skills are open source in the ctxt-io/ctxt-agents GitHub repository.

Context is listed with 1 API on the APIs.io network. Tagged areas include Company, Pastebin, Content Sharing, MCP, and AI Agents.

Context’s developer surface includes changelog, authentication, documentation, support, and 29 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 the provider profile at artifacts.apis.io/ctxt-io/apis.yml: open an issue on github.com/api-evangelist/ctxt-io to ask a question or point us at an artifact you publish.
