Learn how to manage, version, and deliver structured prompts via API. From sign-up to production in minutes.
Up and running in 4 steps.
From sign-up to your first API call in minutes.
Create a Prompt
Sign up, create a project, and add your first prompt. Projects organize prompts by team or application.
Add Blocks
Structure your prompt with typed blocks: role, context, instructions, guardrails, output_format, and custom. Drag to reorder.
Publish a Version
Lock in your prompt version for production use. Versions are immutable snapshots you can roll back to at any time.
Fetch via API
Get your compiled prompt with a single API call. Variables are resolved at fetch time with the values you pass.
How PromptOT works.
Understand the building blocks of structured prompt management.
Blocks
Typed sections (role, context, instructions, guardrails, output_format, custom) that compose into a prompt. Each block has a title, content, type, and sort order.
Compilation
Blocks are filtered (enabled only), sorted by sort_order, and joined as ## Title sections into a single prompt string ready for your LLM.
Variables
Use {{key}} syntax in block content. Variables are resolved at fetch time with values you pass in the API call.
Versions
Publish immutable versions of your prompt. Production API keys always return the published version; development keys return the latest draft.
API Keys
Generate keys scoped to environments (production/development). Keys are hashed with SHA-256 — we never store the raw key.
Webhooks
Get notified when prompts are published, updated, or deleted. Payloads are signed with HMAC-SHA256 for verification.
