Gender-API
Add Gender-API to your product for your customers, and give your AI agents governed access to it.
Embed a Gender-API integration so your customers can infer likely gender from a first name or full name using their own credentials, for use cases such as salutation choice in outbound messaging. Every response carries a confidence indication, so your product can decline to guess below a threshold you set per customer. fastn handles credential storage, rate limiting, and API upkeep, and every lookup is logged per tenant.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let customers resolve a name to a likely gender when personalising a salutation in your product.
Apply a per-customer confidence threshold so low-confidence results fall back to a neutral form.
Enrich records in bulk on import, throttled so a backfill does not exhaust the customer's allowance.
Trigger a lookup when a new contact is created and write the result back to your product.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent checks the inferred value and its confidence before choosing how to address a recipient.
An agent skips personalisation when confidence is low rather than guessing.
An agent enriches a batch of contacts within governed permissions, with each lookup logged.
Example prompt
Check these contact names and list any where the result is below the confidence threshold we set.
Set up Gender-API in 4 steps
- 01Open the Gender-API connector from your fastn dashboard.
- 02Have each customer supply their own Gender-API credentials.
- 03Set the confidence threshold and map the fields your product writes results into.
- 04Call them from your product, or expose them to an agent through the MCP server.
Why teams use the Gender-API integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Gender-API integration without building it. Your customers connect their own Gender-API 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 a Gender-API update is not your on-call problem.
- One integration serves your product and your agents. The same governed Gender-API 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.

Gender-API integration FAQ
How do I add a Gender-API integration to my product?
Enable the Gender-API connector in your fastn dashboard, then let each customer authenticate their own Gender-API account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Gender-API client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Gender-API account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Gender-API 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 Gender-API integration?
Yes. The same connection is exposed to your agents through the fastn MCP gateway, with permissions scoped per tenant and every call audited. An agent checks the inferred value and its confidence before choosing how to address a recipient.
Who maintains the Gender-API integration?
fastn does. When Gender-API 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 a Gender-API 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 Gender-API results be cached?
Per tenant, with a window that matches how fast the underlying data actually moves. Gender-API 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 Gender-API integration?
A common starting point: resolve a name to a likely gender when personalising a salutation in your product. 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 Gender-API integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Gender-API does not change your per-connector cost. You can start free with 3 connected accounts.
