The changelog can be searched, filtered, linked to and followed by feed. ## What changed The /developers page is now a reference in two columns: what a thing is on the left, and on the right a request in cURL, Node.js or Python and the shape of the answer, kept in view as you read. It opens with three paths: what you can build, a first working call in five steps, and what to check before production. Rate limits are stated as numbers: comparison allows 20 requests a minute and 200 an hour from one address, the Model Context Protocol (MCP) server 120 tool calls a minute. Versioning, testing and every endpoint have their own sections, each endpoint with its parameters, its answers and a request you can copy, generated from the published OpenAPI document. The changelog now has a search box, filters by area, type and month that can be shared as a link, a list of upcoming deadlines above the feed, a page for every entry, and feeds by area, by type and for changes that need action. ## Why it changed The reference described the API well but did not help a reader make a first call, did not print the comparison limit, and showed no request or response per endpoint. The changelog could not be filtered, linked to by entry, or followed. ## Who is affected - **Affected:** Developers integrating with the public application programming interface (API), and anyone who follows Trooth's changes. No endpoint, field or response changed. - **Availability:** Public. No account needed. - **Release stage:** Available. - **Areas:** API, Platform. ## What to do **No action required.** No endpoint, field, response or limit changed. The comparison limit the reference now prints is the limit the route already enforced, read from the same constant. **What comes next:** Each entry from here on states who is affected, whether anyone must act, and by when. ## Dates - **Announced:** September 27, 2026, the day this entry was written. Entries are never backdated. - **Released:** September 27, 2026. ## What this does not fix There is still no test environment and no software development kit (SDK); the reference says so and says what to do instead. Neither page has been tested with the developers and buyers it is written for. ## Read more - [Developers](https://trooth.co/developers) - [The changelog feed](https://trooth.co/changelog/rss.xml) - [API changes only](https://trooth.co/changelog/rss.xml?area=api) On this page - What changed - Why it changed - Who is affected - What to do - Dates - What this does not fix - Read more [Improvement](https://trooth.co/changelog?type=improvement)[New](https://trooth.co/changelog?type=new)[API](https://trooth.co/changelog?area=api)[Platform](https://trooth.co/changelog?area=platform) [Back to changelog](https://trooth.co/changelog) ## Related changes - [SEP.27NewA public feedback board, and a comparison you can start with any two companiesNetwork +1](https://trooth.co/changelog/2026-09-27-feedback-board-and-comparison) - [SEP.26NewA bill of materials for every Worker, and Trooth's own record correctedPlatform +1](https://trooth.co/changelog/2026-09-26-worker-bills-of-materials) - [SEP.26ImprovementCounts on a profile now come from the signed witness statementTrust Profiles +2](https://trooth.co/changelog/2026-09-26-counts-from-signed-statement) - [SEP.26ImprovementDisputes are handled privately; framework rollups and the old badge are retiredTrust Profiles +4](https://trooth.co/changelog/2026-09-26-disputes-private-rollups-retired) - [AUG.02NewLaunch: the Trooth Network is openNetwork +1](https://trooth.co/changelog/2026-08-02-network-launch) - [JUL.24NewModel Context Protocol server, incident ledger, ML-BOM export, Guard policy centerMCP server +2](https://trooth.co/changelog/2026-07-24-mcp-server-incident-ledger) ## Follow what changes at Trooth Every entry by email, or a feed narrowed to one area or to the changes that need you to act. ## Product updates by email Occasional notes when something on this page changes.
