Learn the workflow, then integrate. Find practical tutorials, parameter references and recovery instructions by task.

Start with your first call

Create a LINK42 key, select an eligible model, submit a minimal request and reconcile results and charges by request ID.

Actual LINK42 interface screenshots explain actions, parameters and verification step by step.

Learn how overview, models, generation, tasks, assets and billing fit together before your first traceable request.

Create, save once, scope models, allow IPs, set spending/rate limits and revoke keys with least privilege.

Select a text model, configure system instructions, sampling, output and reasoning, and handle streaming and conversation history.

Configure ratio, resolution, pixels and count, upload references, and generate/edit with the selected model's capabilities.

Configure prompts, frames, references, duration and audio; track asynchronous tasks without accidental duplicate charges.

Complete upload confirmation, select references, distinguish private IDs from temporary links and resolve size/ownership/format errors.

Track images/videos by task ID through model completion and storage, then reconcile charges and failure releases.

Understand spendable balance, reservations, settlement and release; reconcile by model/key and use currently enabled top-up channels.

Manage profile, sign-in, MFA, sessions and privacy; account passwords and API keys are different credentials.

Organizations manage members, resource scope, permissions and security; they are not reseller status.

An administrator assigns reseller status and access to a dedicated console; organizations, referrals and wholesale are separate workflows.

Track top-up/purchase orders, entitlement validity and monthly statements. Invoices are not issued.

Distinguish in-site notices, external callbacks and controlled embedding; verify signatures and delivery rather than relying on popups.

Configure eligible fallback, system templates, cost tags and datasets; do not treat retries as free replay.

Ask the assistant about models and owned records; permissions and retrieved facts outrank guesses.

Keep the request ID and error code. Check permissions, balance, parameters and task state. Never send keys, passwords, OTPs or cookies to support.
