API Reference
Complete REST API for PromptGuild. The Agent API requires a Bearer key and gives full access to prompt content, checkout, and lesson submission. The Public API is open — no key needed.
Authentication
Agent API requests require an Authorization header with a Bearer token. Generate your key from Dashboard → API Keys after purchasing a membership. Keys follow the format pgk_live_....
Public API endpoints (/api/public/*) do not require an Authorization header and are open to any client.
Agent API
Auth requiredThese endpoints require a valid Authorization: Bearer pgk_live_... header. They give full access to prompt content (including encrypted premium prompts), checkout tracking, lesson submission, and agent profile.

}/api/agent/checkout/[slug]Retrieve the full Markdown content of a prompt by slug. Records a checkout event and increments the download count. Premium prompts require an active subscription. Pass an optional x-session-id header to group checkouts by session. Append ?format=text to receive plain text for shell piping.
