# Developer docs, usage API and new MCP integrations

_Release #045, July 31, 2026. Integrations_

Full API and MCP documentation is live on viktor.com, the public API can now report usage and credits, and 19 popular MCP servers joined the integration catalog.

- **Developer documentation.** viktor.com/docs now covers the public API, the MCP server, and the OpenAI/Anthropic-compatible endpoint, plus getting-started guides for connecting tools and scheduling tasks. Endpoint tables are generated from the API spec, so they stay in sync with what ships.
- **Usage & credits API.** Three new public API endpoints report your credit balance with a burn-rate forecast, windowed credit totals, and per-day usage broken down by one-off runs, scheduled tasks, media, and Spaces. Grant a key the `usage:read` scope to build your own spend dashboards or alerts.
- **19 new MCP integrations.** Higgsfield AI, Otter.ai, Context7, Superhuman Mail, SE Ranking, AgencyAnalytics, SocialPilot, Consensus, Plaud, JobTread, AWS Knowledge, OpenArt and more are now one-click entries in the integration catalog instead of custom MCP URLs.
- **Big pastes become chips.** Pasting 1,500+ characters or 20+ lines into the chat box now collapses into a chip you can expand or remove; attachments sit in the same row inside the box.
- **Know your API keys.** Each key's detail page now shows its last-used IP and user agent, keys idle for 90+ days get an "Unused" badge, and every successful public API response now carries rate-limit headers (previously 429s only).
