Frequently Asked Questions

What is Primex?

A platform for building with AI through one account and one prx- key. It spans models, agents, image and video, speech, OCR, documents, translation, vision, language, safety, web search, and client-executed tools. Use direct APIs, compatible clients, or Primex Chat with pay-as-you-go credits or windowed plans.

How do I get started?

Open Primex API Keys, create a key, and add credit in Billing. Then point your tooling at the gateway. See Getting Started.

Is the API OpenAI- or Anthropic-compatible?

Both. There's an OpenAI-compatible base URL (https://gateway.primexos.com/v1) and an Anthropic-compatible one (https://gateway.primexos.com, no /v1). Change the base URL and key; your SDK stays the same. See Authentication.

Which tools work with Primex?

Cursor, Windsurf, Codex CLI, Claude Code, Cline, Continue, and the raw OpenAI / Anthropic SDKs. See Client Setup.

What models are available?

The eight families cover models and reasoning; agents, code, and tools; image and video; vision and documents; voice and audio; knowledge and search; language and text; and safety and trust. See Capabilities. The live catalogue in the app shows exactly what is enabled.

How are images and video billed?

The unit depends on the service. It may be tokens, images, megapixels, video seconds, audio minutes, characters, pages, records, searches, calls, or sessions. See Billing and the relevant endpoint page.

Do I need to poll for image/video results?

No. Primex handles generation and returns the finished result on the same request. There is no separate job ID to poll. See Video.

Can I use my own MCP tools?

Yes. Attach a hosted MCP server to a Responses-passthrough model. See MCP Servers.

What happens when my balance runs out?

Requests return 402 Payment Required until you top up. On a flat-fee plan, requests are limited once you hit a rolling allowance window until it refills.

Does a failed request cost anything?

Failed requests aren't billed. Successfully delivered usage is metered, so usable output delivered before a later stream error may still be charged. See Billing.

Can I get a refund?

Failed requests aren't charged in the first place. If a charge slips through incorrectly, Primex support can refund it to your paid balance (idempotent and logged). Review every charge in Usage.

What payment methods are accepted?

Crypto is supported. Hosted card, bank, wallet, and local payment methods also appear when configured. Checkout shows the methods available for your order.

Is Primex only a Telegram app?

No. The Browser App supports email signup and sign-in, Catalog, Playground, Setup, API keys, credit purchases, Billing, Usage, Settings, and Support. The Telegram Mini App provides another customer workspace. Connect sign-in methods to the same account to share its AI balance and history. Primex Chat and Create use Continue with Primex; compatible developer tools and direct APIs use your prx- key.

Can I buy credits without Telegram?

Yes. Sign in to Billing and choose Add funds. Credit purchases are available in both the Browser App and Telegram Mini App. New subscription-plan sales are currently paused; see Billing.

Are there rate limits?

Yes. Primex enforces request limits per key and across each account, concurrency limits, and any configured monthly key spend cap. Inspect the rate-limit headers and honor Retry-After; see Errors & Limits. Contact Support to discuss higher-volume requirements.

How does Primex handle my request data?

Direct API content is processed to provide the request and sent to the serving upstream. Ordinary request and successful response bodies are not written to the Usage ledger, but Primex retains usage and operational metadata, and other surfaces such as Chat, Create, temporary files, and browser-local Playground state have their own lifecycles. See the Privacy Policy and Policies.

How do I manage my key or make an account or data request?

Keys are created and revoked in Primex API Keys. For account or data requests, contact Support in the Browser App or the Telegram Mini App. Available actions depend on the data and product surface involved.
