Account API Key Extract Schedule Notifications Team

Create Your Account

# Register via API — or use https://extract.kafcenter.com/dashboard/register
curl -X POST "https://extract.kafcenter.com/auth/register" \
  -H "Content-Type: application/json" \
  -d '{
    "email": "you@example.com",
    "password": "YourSecurePass123",
    "name": "Your Name"
  }'

Response: {"access_token":"eyJ...","refresh_token":"eyJ...","token_type":"bearer"}

💡 Pro tip: The access_token expires in 30 minutes. Use the refresh_token to get a new pair. Or log in to the User Dashboard to manage tokens visually.

Get Your API Key

API keys authorize extraction requests. Create one via the dashboard or programmatically. Hobby tier includes 1 key.

# Create an API key (requires Bearer token from Step 1)
curl -X POST "https://extract.kafcenter.com/api/v1/keys" \
  -H "Authorization: Bearer eyJ..." \
  -H "Content-Type: application/json" \
  -d '{"name":"Hobby Key","rate_limit":60}'

Response: {"id":"550e...","key":"kaf_live_AbCdEf12345","name":"Hobby Key","rate_limit":60}

💡 Pro tip: Set descriptive name values. This makes it easy to identify which key belongs to which project when reviewing usage later.

Your First Extraction

Pass a URL and a schema — we return structured JSON. CSS selectors for precise extraction, or AI mode for zero-configuration.

# Extract product data with CSS selectors
curl -X POST "https://extract.kafcenter.com/api/v1/extract" \
  -H "X-API-Key: kaf_live_AbCdEf12345" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://books.toscrape.com/catalogue/",
    "schema": {
      "fields": [
        {"name": "title", "selector": "h3 a", "type": "text"},
        {"name": "price", "selector": ".price_color", "type": "text"},
        {"name": "link", "selector": "h3 a", "type": "attribute", "attribute": "href"}
      ]
    }
  }'

Response: {"status":"success","data":[{"title":"A Light in the Attic","price":"£51.77","link":"a-light-in-the-attic_1000/index.html"},...]}

📌 Field types reference: text (innerText), attribute (href/src/etc), html (raw), exists (boolean), markdown (clean MD), screenshot (PNG).

🧠 AI mode: Send "mode": "ai" with an ai_prompt description. No selectors needed — kimi-k2.6:cloud figures it out.

Schedule Recurring Jobs

Monitor websites automatically. Cron expressions, webhook delivery, and change detection — all handled.

# Schedule: check prices every 6 hours
curl -X POST "https://extract.kafcenter.com/api/v1/extract/schedule" \
  -H "Authorization: Bearer eyJ..." \
  -H "Content-Type: application/json" \
  -d '{
    "name": "Price Monitor",
    "url": "https://shop.example.com/product/123",
    "cron_expression": "0 */6 * * *",
    "fields": [{"name": "price", "selector": ".price", "type": "text"}],
    "webhook_url": "https://hooks.slack.com/services/T.../B.../xxx"
  }'

Response: {"id":"sched_...","next_run":"2026-05-28T12:00:00Z","status":"active"}

⏰ Cron examples:
0 */6 * * * — every 6 hours · 0 9 * * 1-5 — 9am weekdays · 0 0 1 * * — midnight on the 1st

Set Up Slack Notifications

Get formatted extraction results pushed to Slack automatically. No code changes needed — just add your webhook URL.

# 1. Create Slack Incoming Webhook: api.slack.com/messaging/webhooks
# 2. Test it from our side before scheduling

curl -X POST "https://extract.kafcenter.com/api/v1/integrations/slack/test" \
  -H "Authorization: Bearer eyJ..." \
  -H "Content-Type: application/json" \
  -d '{"webhook_url": "https://hooks.slack.com/services/T.../B.../xxx"}'

✅ Auto-detection: Kaf Extract detects Slack URLs automatically and formats messages with Block Kit (header, preview, timestamps). No configuration needed.

Invite Your Team

Share workspaces, API keys, and usage dashboards with your team. RBAC enforced: owner, admin, editor, viewer.

# 1. Create an organization
curl -X POST "https://extract.kafcenter.com/api/v1/orgs" \
  -H "Authorization: Bearer eyJ..." \
  -d '{"name":"Production Team","slug":"prod-team"}'

# 2. Invite a team member (they must register first)
curl -X POST "https://extract.kafcenter.com/api/v1/orgs/{org_id}/members" \
  -H "Authorization: Bearer eyJ..." \
  -d> '{"email":"colleague@example.com","role":"editor"}'

👥 Roles: owner (full control) → admin (manage members) → editor (create/modify extractions) → viewer (read-only). API keys created at org-level are shared across all members.

❓ Frequently Asked Questions

What's the rate limit?

Hobby: 60 requests/min. Pro: 300/min. Enterprise: 1,000/min. Per-API-key limits can be lower if you set them in the dashboard.

Which websites work?

Any public website. We use a headless browser so JavaScript-rendered SPAs are fully supported. Sites with aggressive bot protection may require our proxy pool (Pro/Enterprise).

How much does it cost?

Hobby is free forever — 1,000 extractions/month. Pro is $29/mo with 50K extractions, AI mode, batch jobs, and webhooks. Enterprise is $199/mo with dedicated proxies and SLA. See the pricing page.

What if I get a 429 error?

You've hit your rate limit. Wait for the 60-second window to reset, or upgrade your plan. The response includes Retry-After and X-RateLimit-* headers.

Can I export results?

Yes. Results are JSON by default. Add ?format=csv or ?format=markdown to any extraction endpoint for direct export.

How do I reset my password?
