Why Build With IndexFlow API?

High-throughput infrastructure engineered specifically for programmatic SEO and link builders.

5-Channel Multi-Ping

URLs are submitted simultaneously through Google PubSub, IndexNow, XML ping networks, and social discovery feeds.

High Throughput Batching

Send up to 10,000 URLs in a single payload. Our asynchronous worker queue handles processing without socket timeouts.

Pre-Check Deduplication

Optional auto-filtering flags URLs already indexed by Google before consuming credits, saving you up to 40% on costs.

Frequently Asked Questions

How is IndexFlow's API different from Google's official Indexing API?

Google's official Indexing API is strictly restricted to JobPosting and BroadcastEvent structured data and cannot be used for standard content or third-party backlinks. IndexFlow's API supports any URL, tier-1/tier-2 backlinks, guest posts, and programmatic pages through 5 automated discovery channels without Google account suspensions.

What is the rate limit for the IndexFlow Backlink Indexing API?

Standard accounts can submit up to 10,000 URLs per request with up to 120 requests per minute. Agency and Enterprise accounts have unlimited rate limits and dedicated IP routing.

Are code examples available in Python and Node.js?

Yes! We provide copy-paste code snippets in cURL, Python (requests/aiohttp), Node.js (fetch/axios), and PHP with full TypeScript type definitions.

Can I use webhooks to sync indexed statuses to my CRM or SEO tool?

Yes. Configure a webhook URL in your dashboard or via API, and our servers will send JSON payloads whenever a URL changes status from pending to indexed.
