Why does AI integration still require so many accounts?
API429 gives you one key instead of dozens. Fewer switches, more results.
Questions and answers
How does API429 save money?
API429 publishes each available model rate directly from the production balancer. Where one exact official counterpart exists, the models and pricing catalog shows a like-for-like reference; the result depends on the model, billing metric, and request parameters. You also waste less on failed jobs, extra retries, and manual work around limits.
Does API429 remove annoying limits?
API429 helps your product run more steadily by smoothing traffic spikes and reducing stops caused by limits. We cannot honestly promise "no limits ever": models and providers still have technical constraints. 429 is the technical name for one of those errors.
What payment methods do you accept?
We support Russian bank cards, bank transfers where applicable, and cryptocurrencies (USDT, TON). Available methods are shown in the dashboard for your account.
Which models are available?
The list depends on your token and plan. The most accurate way to check access is the dashboard or GET /v1/models.
Do I need to rewrite my code?
Usually no. If you already use the OpenAI SDK, you often only change the base URL to https://gateway.api429.com/v1 and use an API429 token.
Do you train on my prompts?
No. API429 is an access layer. Technical request data is needed for billing, diagnostics, and service quality, but prompts and responses are not used as a public training dataset.
