## Free account and IP trial

A registered free account includes 200 credits per day and uses an API key. That covers up to 200 ordinary 1-credit lookups; selected AI modes use 2 credits per item.

The V2 IP trial provides 10 credits per public IP for a 24-hour window without signing up. Missing, malformed or unknown API keys use this trial. People behind the same public IP share it, and V1 trial usage draws from the same IP balance. Known disabled, expired or restricted keys do not fall back to the trial.

## V2 credit costs

Credits measure the work completed, not the number of HTTP requests. These tariffs apply to V2 name, email and username lookups. V1 and V2 use your existing API key and share the same account balance.

A successful unknown result with gender: null is billed at the selected mode's tariff. Input validation errors before billing do not consume credits; failed predictions are not charged after a confirmed refund. Check billing_status when a billing outcome is unconfirmed.

A batch is billed per successful item, not once per HTTP request. Batch items default to dataset-only mode; set fallback, always or forceToGenderize for each item when needed. A batch with 50 successful standard 1-credit items costs 50 credits. API-key batches allow up to 50 items; IP trial batches allow up to 10.

At least 1 remaining credit is enough to begin a single or batch operation. The full tariff can make your balance negative; a 2-credit lookup started with 1 credit leaves -1. Zero or negative balances block new billable operations.

Repeated requests are separate operations with normal billing. Avoid automatically retrying a request whose outcome or charge is unknown.

| Operation | Credits per item | How it works |
| --- | --- | --- |
| Dataset only | 1 | With ai_mode: off, look up the dataset without calling AI. |
| Standard lookup with automatic AI fallback | 1 | With ai_mode: fallback, check the dataset first and ask AI if no gender is found. The total is 1 credit, even when AI is used. This is the default for single lookups. |
| Explicit AI lookup | 2 | With ai_mode: always, skip the dataset and use AI. |
| Nickname inference: dataset result | 1 | With forceToGenderize: true, check the dataset first. A resolved dataset gender costs 1 credit. |
| Nickname inference: AI result | 2 | If the dataset cannot resolve gender with forceToGenderize: true, use AI to interpret names, emails or usernames without requiring a real given name. The total is 2 credits. |
| Phone validation | 1 | A completed number validation costs 1 credit, including a valid: false result. |
| Check your balance | 0 | GET /api/v2/usage does not consume credits. It still counts toward request rate limits. |

## Request limits

V2 applies request rate and concurrency limits on every plan. Credit balance and request rate limits are separate: handle HTTP 429 and wait for Retry-After before sending another request. See the V2 documentation for current service defaults and response headers.

- [V1 documentation](https://www.genderapi.io/api-documentation/v1)

## Is one API request always one credit?

No. A standard V2 lookup costs 1 credit, including automatic AI fallback. Explicit ai_mode: always costs 2 credits. forceToGenderize costs 1 for a resolved dataset result or 2 when AI is used. A batch is charged per successful item, and a successful unknown result is billable.

## What is the difference between the free account and the IP trial?

A registered account uses an API key and includes 200 free credits per day. The no-key V2 trial has 10 credits per public IP in a 24-hour window, shared with other users of that IP and V1 trial usage. Normal lookup tariffs apply to both.

## Do paid plans have request limits?

Yes. V2 enforces request rate and concurrency limits independently of your credit balance. A larger credit package does not remove these limits. Handle HTTP 429 and follow Retry-After; consult the V2 documentation for current limits.
