How this service works
Replace the BYO env blob. KMS-re-encrypted at rest; never echoed. 📖 Full guide: https://scheduler.withzero.xyz/llms.txt
Output
Returns the task UUID, a new env_key_version string (used to detect when env was last rotated), and an array of env_keys listing the variable names now stored — actual values are never returned in any response.
Example use cases
Rotate API credentials for recurring job
“My scheduled task with ID f47ac10b-58cc-4372-a567-0e02b2c3d479 needs its credentials rotated — replace the env vars with OPENAI_API_KEY=sk-newkey999 and STRIPE_SECRET=sk_live_newstripe, and remove any old keys.”
Clear all secrets from a decommissioned task
“I'm decommissioning task 550e8400-e29b-41d4-a716-446655440000 — please wipe all its environment variables by replacing them with an empty set.”
Bootstrap new environment config for cloned task
“I just cloned a task and now need to set up its environment variables from scratch: set AWS_ACCESS_KEY_ID=AKIAIOSFODNN7, AWS_SECRET_ACCESS_KEY=wJalrXUtnFEMI, and REGION=us-east-1 for task 6ba7b810-9dad-11d1-80b4-00c04fd430c8.”
Technical details
Endpoint
PUThttps://agents.withzero.xyz/api/v1/scheduler/tasks/{id}/envWhen to prefer
Use this endpoint when you need to fully replace all environment variables for a task in one atomic operation — it performs a complete replacement, not a partial patch. Prefer this over patching individual keys when rotating credentials, bootstrapping a cloned task's config, or clearing all secrets. The KMS-at-rest encryption and no-echo response make it suitable for storing sensitive API keys and secrets.
Side effects
- Task ID not found or not owned by caller — 404 or 403 response
- Invalid env key format (must match ^[A-Z_][A-Z0-9_]*$) — 400 validation error
- Env value exceeds 4096 character limit — 400 validation error
- KMS encryption failure — 500 server error
- Malformed request body or missing required `env` field — 400 error
