pricing

HiAPI Pricing & Plans

HiAPI operates on a freemium, pay-as-you-go pricing model, allowing users to pay only for the resources consumed. New users receive a $1 free credit, which can generate approximately 50 images. Pricing is typically per-unit (e.g., per image, per clip) and varies by the specific AI model utilized. The platform provides transparent cost examples for different resolutions and model types.

Free Tier: Includes $1 free credit for new users, sufficient for approximately 50 images.
GPT Image 2: Priced at $0.03 per image.
Nano Banana 2: Priced at $0.05 per image.
FLUX 1.1 Pro: Priced at $0.05 per image.
Seedance 2.0: Priced up to $0.823 per clip.
Usage Pricing (1K resolution): $0.03 per image. Generating 1 image at 2K resolution costs approximately $0.04, and at 4K resolution, approximately $0.06.

Pros

+Unified API for diverse generative AI models (image, video, audio, text) simplifies integration.
+OpenAI-compatible requests allow for easy migration and minimal code changes.
+Freemium model with $1 free credit enables initial testing without financial commitment.
+Persistent output links eliminate the need for separate storage infrastructure for generated assets.

Cons

−User reviews and reception are currently scarce, making it difficult to assess broad user satisfaction.
−Specific company details like founding year or headquarters are not publicly available.
−Default API rate limits (60 requests/minute, 10 concurrent) may require contacting support for higher tiers.
−Pricing varies significantly by model and resolution, requiring careful cost management for diverse use cases.
−While offering unified access, the specific selection of aggregated models may not cover every niche requirement.
