Name intelligence for smarter conversations

Your AI agent uses Gender API to identify gender from names and emails, detect country of origin, and adapt communication style, all happening invisibly during customer interactions.

Gender API

Use Cases

Personalization through name intelligence

See how businesses use Gender API through AI agents to personalize salutations, adapt messaging, and enrich customer records without manual data entry or awkward demographic questions.

Personalized Email Greetings at Scale

Your marketing platform sends 50,000 newsletters. Before each send, the AI agent queries Gender API with the subscriber's first name to determine the correct salutation. 'Dear Mr. Johnson' and 'Dear Ms. Chen' replace generic 'Dear Customer' greetings. Open rates improve because recipients see personalized subject lines. The entire enrichment runs without any subscriber ever being asked to self-identify.

Real-Time Chat Personalization

A visitor enters their name in the chat widget. Before responding, the AI agent calls Gender API to detect gender and adjusts the conversation tone and pronoun usage accordingly. The customer feels recognized from the first message. Support satisfaction scores rise because interactions feel natural and respectful rather than robotic.

CRM Data Enrichment for Sales Teams

A sales rep imports 200 new leads from a trade show. Many records have only names and emails. The AI agent runs each name through Gender API with the country of origin endpoint, adding gender and likely nationality to the CRM profiles. Reps now know whether to write 'Dear Sir' or 'Dear Madam' in their outreach, plus gain demographic context for localized pitches.

FAQs

Frequently Asked Questions

How accurate is Gender API's gender detection from first names?

Gender API uses AI-powered models trained on millions of names across 100+ countries. Each response includes a confidence score (0-100) so you can set thresholds. Names like 'Maria' return high confidence in most regions. Ambiguous names like 'Alex' return lower confidence, and you can configure the agent to skip personalization when confidence is below your threshold.

Can the agent detect gender from email addresses like info@ or admin@?

Gender API works best with personal email addresses that contain name patterns like john.smith@company.com. Generic addresses like info@ or admin@ will return low confidence or no result. The agent handles these cases gracefully by defaulting to gender-neutral language instead of forcing an incorrect salutation.

How does the country parameter improve accuracy for cross-cultural names?

Names have different gender associations across cultures. 'Andrea' is female in English-speaking countries but male in Italy. Passing an ISO 3166 country code (like 'US' or 'IT') lets Gender API apply regional conventions. The agent can also pass IP addresses or browser locale for additional geographic hints.

Does Tars store the gender data returned by Gender API?

No. Tars queries Gender API in real-time during conversations. The gender result is used to personalize the current interaction only. If you want to persist the data, your agent can write it to your CRM, but Tars itself does not maintain a database of gender determinations.

What is the country of origin endpoint, and how does it differ from gender detection?

The country of origin endpoint analyzes a name and returns the most likely countries where that name is common, along with probability scores. It is separate from gender detection and provides demographic context. Your agent can use both endpoints together to build a richer profile: gender plus likely nationality from a single name.

How many API credits does each query consume?

Each individual query (by first name, full name, or email) consumes one credit. The Get Statistic endpoint lets the agent check your remaining credits and usage history before processing batches. You can set up alerts when credits run low so operations never stop unexpectedly.

Can the agent process names in non-Latin scripts like Chinese, Arabic, or Cyrillic?

Yes. Gender API supports names in many languages and scripts. The system analyzes the characters against its global name database regardless of writing system. Providing the correct country code alongside non-Latin names significantly improves accuracy for region-specific gender conventions.

What happens when the API returns an ambiguous or unknown result?

The agent checks the confidence score in every response. For ambiguous names with low confidence, you configure fallback behavior: use gender-neutral language, skip personalization entirely, or ask the customer directly. The agent never forces an incorrect assumption on uncertain data.
