The shift

From maintaining data infrastructure
to shipping product features

Before

  • Integrating every data source separately
  • Maintaining scrapers, proxies, and rate limits
  • Normalizing inconsistent schemas
  • Fixing broken providers and API changes
  • Building infrastructure instead of product

After

  • One API for web, social, apps, and search
  • One normalized interface across sources
  • ReplyNodes handles routing and data infrastructure
  • Combine sources without maintaining integrations
  • Ship agent features faster

FAQ

Frequently asked questions

What is ReplyNodes?

ReplyNodes provides read-only data APIs for AI agents. Use one fetcher gateway to search and retrieve public web, social, app, and scraped data. Write actions are not part of this launch.

How does ReplyNodes billing work?

ReplyNodes uses subscriptions plus unified credits. Free includes 500 credits once. Developer is $19/month with 10,000 credits each month. Pro is $99/month with 100,000 credits each month. Annual billing gives you two months free.

What are credits?

Credits are the shared usage unit for metered, read-only fetcher requests. Your plan includes a defined monthly or one-time credit allowance. Developer and Pro can use optional overage only after you set an explicit monthly cap.

What happens when I reach my included credits?

Requests stop when your included credits are exhausted unless you have configured an overage cap. Free has no overage. Developer overage is $20 per 10,000 credits. Pro overage is $10 per 10,000 credits.

Are data reads charged?

Every successful read uses the endpoint's configured credit cost. Provider failures, blocked requests, and HTTP 4xx/5xx responses cost zero. A valid response with zero results is still billable.

Which API key should I use?

Fetcher owns billing and key management. Each user has exactly one active, long-lived fetcher API key. Use that key with the fetcher API. App API keys and short-lived playground credentials are not part of this launch.

Which providers are included?

Only read-data provider surfaces enabled in the current fetcher deployment should be shown. Availability is route-specific, so check the live capabilities reference before integrating.

Can I use OpenAPI or Try It?

Yes. OpenAPI can remain available for Scalar, schema inspection, and Try It. Client code generation is deferred.

Is the data API read-only?

Yes. Every data operation reads public sources. The API does not schedule, delete, follow, or mutate platform accounts.
