# Gamma Hello World ## Overview Generate your first presentation using Gamma's async Generate API. The workflow is: POST to create a generation, poll for status, then retrieve results (gammaUrl + exportUrl). ## Prerequisites - Completed `gamma-install-auth` setup - Valid `GAMMA_API_KEY` environment variable - Pro account with available credits ## The Generate-Poll-Retrieve Pattern All Gamma generations are asynchronous: 1. **POST** `/v1.0/generations` — submit content, receive `generationId` 2. **GET** `/v1.0/generations/{generationId}` — poll every 5s until `completed` or `failed` 3. **Result** — `gammaUrl` (view in app) + `exportUrl` (download PDF/PPTX/PNG) ## Instructions ### Minimal curl Example ```bash # Step 1: Create generation GENERATION=$(curl -s -X POST \ "https://public-api.gamma.app/v1.0/generations" \ -H "X-API-KEY: ${GAMMA_API_KEY}" \ -H "Content-Type: application/json" \ -d '{ "content": "Create a 5-card presentation about the benefits of AI in business", "outputFormat": "presentation" }') GEN_ID=$(echo "$GENERATION" | jq -r '.generationId') echo "Generation started: $GEN_ID" # Step 2: Poll until complete (every 5 seconds) while true; do STATUS=$(curl -s \ "https://public-api.gamma.app/v1.0/generations/${GEN_ID}" \ -H "X-API-KEY: ${GAMMA_API_KEY}") STATE=$(echo "$STATUS" | jq -r '.status') echo "Status: $STATE" [ "$STATE" = "completed" ] || [ "$STATE" = "failed" ] && break sleep 5 done # Step 3: Retrieve results e...
