Integration details

Description

Versionly monitors third-party APIs in your GitHub repos (Stripe, Twilio, and more). When a vendor ships a breaking change, Versionly maps impact to your call sites, explains what broke, and can open a fix pull request for you to review. Connect your Versionly account to ask about scans, findings, monitored APIs, repos, and billing — and to trigger impact analysis or auto-fix workflows from ChatGPT.

Tools

18 tools agents can invoke

Map upstream API changes to files and lines in a connected GitHub repo. Prefer this over check_api_changes when a repo is in context. Needs an active plan.
Diff monitored OpenAPI specs and changelogs for breaking changes. First snapshot is a baseline, not a breaking change. Creates a scan (needs an active plan). Prefer analyze_impact when a repo is in context.
Open a GitHub pull request with Versionly auto-fix patches. Never merge. Confirm with the user first. Pass scan_id to reuse patches from generate_fix. Requires Guardian or Command and a GitHub App install.
Discover which third-party APIs a connected GitHub repo actually uses. Confirm with the user. Requires the Versionly GitHub App.
Explain a stored finding: what changed, where, and how to migrate. Pass finding_id, or scan_id plus optional vendor_key. If neither is known, run analyze_impact first.
Generate proposed code patches for affected files. Does not open a GitHub PR. Confirm with the user first. Requires Guardian or Command. Use create_pull_request afterward with the returned scan_id.
Get a connected Versionly GitHub project by id.
Get one scan with findings, summary, and pull requests.
Get the workspace plan, whether scans are live, and whether auto-fix PRs are allowed. Use after a 402/403 or when the user asks what plan they are on.
Check whether the Versionly GitHub App is installed. Use when tools fail with no installation or the user asks to connect GitHub.
List monitored third-party HTTP APIs for this workspace. Dependencies means vendor APIs (Stripe, Twilio), not npm or pip packages. If repo_id is set, also include APIs detected in that repo.
List recent breaking-change findings across scans.
List Versionly-opened GitHub pull requests for this workspace. Never merge them.
List GitHub repositories connected to this Versionly workspace. Use when the user asks which projects are connected.
List recent Versionly scan runs so you do not re-scan to answer history questions.
Start monitoring selected detected APIs so Versionly can diff their OpenAPI specs. Confirm with the user.
Search the Versionly vendor catalog to see if an API can be monitored before calling monitor_apis.
Live monitoring cards for tracked APIs: changelog health, deprecations, and next-plan hints.
