Ahrefs
Add Ahrefs to your product for your customers, and give your AI agents governed access to it.
The Ahrefs v3 API is served from https://api.ahrefs.com/v3 with a bearer token, and an unauthenticated call returns 403 rather than 401, which is worth knowing when you are probing whether a token has been revoked. Endpoints are grouped under site-explorer, keywords-explorer and rank-tracker, and the same target string means different things depending on the mode parameter, where exact, prefix, domain and subdomains each change the row set and the cost. Consumption is measured in units drawn from a subscription allowance and the cost scales with the rows returned, so the select and limit parameters are not just conveniences, they are the main lever on spend. Historical endpoints require an explicit date, and asking for a date before the subscription's history window returns nothing rather than an error. fastn holds each customer's Ahrefs token, keeps unit spend attributable to the tenant that caused it, and maintains the connection as tokens change.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let a customer connect their own Ahrefs subscription so report pulls draw on their units rather than a shared key
Show backlink and referring domain counts for a customer's domain inside your reporting dashboard
Pull keyword metrics for a list a customer maintains and refresh them on a schedule
Read rank tracker positions and surface movement alongside your own conversion data
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
Let an agent fetch the current metrics for a domain and explain what changed since the last pull
Have an agent compare a customer's domain against a competitor using the same mode and date so the numbers are comparable
Audit per tenant how many units an agent spent, since row count and mode drive the cost of each call
Example prompt
How have referring domains for our site changed over the past three months?
Set up Ahrefs in 4 steps
- 01Enable the Ahrefs connector from your fastn dashboard.
- 02Have each customer authorise their own Ahrefs account, so calls run under their credentials rather than a shared key.
- 03Decide which lookups, results and reports your product needs, map those fields, then enable the actions and triggers you want.
- 04Call it from your product and expose it to your agents through the same governed connection.
Why teams use the Ahrefs integration
What you get by embedding it with fastn instead of building it yourself.
- Ship an Ahrefs integration without building it. Your customers connect their own Ahrefs account inside your product and work their lookups, results and reports there, with no per-customer code on your side.
- Handle the part that actually costs time: these are metered read sources, so an uncached lookup on every page view burns the customer's allowance. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so an Ahrefs update is not your on-call problem.
- One integration serves your product and your agents. The same governed Ahrefs connection powers in-product features and gives AI agents scoped, audited access, so you answer questions from an authoritative outside source without holding that data yourself without wiring it twice.

SnowflakeAhrefs integration FAQ
How do I add an Ahrefs integration to my product?
Enable the Ahrefs connector in your fastn dashboard, then let each customer authenticate their own Ahrefs account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Ahrefs client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Ahrefs account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Ahrefs account and only ever sees their own lookups, results and reports. That per-tenant isolation is the point of an embedded integration: you support the long tail of customer setups without maintaining an integration per customer.
Can AI agents use this Ahrefs integration?
Yes. The same connection is exposed to your agents through the fastn MCP gateway, with permissions scoped per tenant and every call audited. Let an agent fetch the current metrics for a domain and explain what changed since the last pull
Who maintains the Ahrefs integration?
fastn does. When Ahrefs changes an endpoint, deprecates a field or alters its auth, the fix lands in the connector rather than in your backlog, and your customers' connections keep working.
Whose credentials does an Ahrefs lookup run under?
Each customer's own. Quota and cost land on the customer that caused them rather than on a shared key you have to meter and re-bill, and one heavy customer cannot exhaust another's allowance.
How should Ahrefs results be cached?
Per tenant, with a window that matches how fast the underlying data actually moves. Ahrefs is a read source rather than a system of record, so the same query returns the same answer until the source changes, and caching is the difference between a sustainable integration and one that exhausts a customer's allowance on a busy page.
What can I build with the Ahrefs integration?
A common starting point: let a customer connect their own Ahrefs subscription so report pulls draw on their units rather than a shared key. Teams also use it for the other use cases listed above, and expose it to agents for governed reads and writes.
How much does the Ahrefs integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Ahrefs does not change your per-connector cost. You can start free with 3 connected accounts.
