List all Worker scripts in your account. Returns each Worker's name, timestamps, and whether it serves static assets.

Get a Worker's settings (bindings, compatibility date and flags, placement, observability) plus its cron triggers and workers.dev subdomain status.

Download a Worker's deployed source code. Module-syntax Workers return one entry per module; service-worker-syntax Workers return a single script.

Deploy a local directory as a static site on Workers (assets-only Worker): builds the file manifest, uploads only files Cloudflare doesn't already have, and deploys. Newly created sites are served on workers.dev. Set not_found_handling to 'single-page-application' for SPAs. _headers/_redirects at the directory root are applied as configuration (not uploaded), and .assetsignore rules (gitignore-style) exclude files from the deploy.

Create a new deployment of an assets-only Worker that reuses its previously uploaded files (keep_assets) — useful to change html_handling or not_found_handling without re-uploading the site.

Upload and deploy a Worker script (ES modules) with optional bindings (plain_text, secret_text, kv_namespace, r2_bucket, d1, assets). Replaces the Worker's code and binding set if it already exists. Set keep_assets to retain a site's static assets while updating code. By default the Worker is served on workers.dev.

Permanently delete a Worker script, including its versions, deployments, and any static assets. Set force to delete even when other resources depend on it.

Update a Worker's settings (bindings, compatibility date/flags, logpush, observability) without re-uploading its code. Note: bindings REPLACE the Worker's full binding set.

List a Worker's versions (newest first): version ID, number, author, source, and deploy message. Versions are immutable snapshots; use list_deployments to see which are live.

List a Worker's deployments (newest first). Each deployment maps traffic percentages to one or more versions; the newest deployment is the live one.

Get a Worker version's detail: bindings, compatibility date/flags, handlers, and usage model for that immutable snapshot.

Upload a new Worker version WITHOUT deploying it — live traffic is unchanged until the version is referenced by create_deployment. Use for staged rollouts.

Point live traffic at Worker versions: a single version at 100%, or a gradual rollout splitting traffic across two versions (e.g. 90/10). Percentages must sum to 100.

Roll a Worker back by deploying an older version at 100% traffic. Only the 100 most recent versions are eligible; bound resources (KV, R2, D1 data) are NOT reverted.

Get a Worker's cron triggers (scheduled events).

List custom domains attached to Workers in this account. Optionally filter by Worker name, hostname, or zone.

Attach a custom domain to a Worker. The domain's zone must be active in this Cloudflare account (external zones are not supported); Cloudflare creates the DNS record and certificate automatically.

Detach a custom domain from its Worker. The hostname stops routing to the Worker (and its previews).

Enable or disable serving a Worker on its ..workers.dev subdomain, and optionally version preview URLs.

Replace a Worker's full cron trigger set (the Worker must export a scheduled handler). Pass an empty list to remove all triggers.

Query a Worker's logs (Workers Logs / observability). Returns the most recent matching events with message, outcome, request, and timing. The Worker must have observability enabled (deploy_worker's enable_observability or update_worker_settings).

Verify the API token is valid and connection to Cloudflare is working. Useful for troubleshooting authentication issues.
