Generative models. One API.

Q: How do I get the result?

POST /images/generate returns 202 with an id. GET /creations/{id} then returns the status and result_urls; instead of polling, pass webhook_url and we'll send an event when the image is ready.

Q: Can an AI agent connect Rendergrid?

Yes: an MCP server, skills for Claude Code and Cursor, agents.md and llms.txt — your agent will find the models, prices and request examples on its own. The generate_image tool waits up to 45 seconds for the result; if the image isn’t ready, it returns its id — call get_creation next.

10 image models from Google and OpenAI at up to 4K through one API. Pay only for successful generations.

09FAQ

Questions and answers

Pricing, payment and integration in brief. The details are in the docs.

What is Rendergrid?

An image generation API: 10 models behind one key and one balance, at up to 4K. From Google: Nano Banana Pro, Nano Banana 2, Nano Banana 2.1, Nano Banana Flash, and Nano Banana 2 Lite; from OpenAI: GPT Image 2, GPT Image 2 HD, GPT Image 2.5, GPT Image 2.5 Sunburst, and GPT Image 2.5 Flare.

How much does one image cost?

From $0.015 (Nano Banana Flash and Nano Banana 2 Lite at 1K) to $0.07 (Nano Banana Pro at 4K). The price depends on the model and resolution and is charged per image, with no subscription.

How much cheaper is it than official prices?

Up to 70%. The biggest difference is Nano Banana Pro at 1K: $0.04 instead of $0.134 from Google. For OpenAI we compare the price of a square image: GPT Image 2 at medium quality; GPT Image 2.5, Sunburst and Flare at high quality. The comparison for every model and resolution is on the pricing page; official prices checked on October 26, 2026.

What happens if a generation fails?

A failed request is free: the amount goes straight back to your balance. Both the charge and the refund show up in your transaction history.

Can I try it for free?

There is no trial balance; a failed request is free: the amount goes straight back to your balance. Start with a small USDT top-up — the price is charged per image.

How do I pay?

Top up your balance in USDT in the portal. Prices and balance are in US dollars, charged per image.

Which resolutions are supported?

Nano Banana Pro, Nano Banana 2, Nano Banana 2.1, GPT Image 2 HD, GPT Image 2.5 Sunburst, and GPT Image 2.5 Flare support 1K, 2K, and 4K; Nano Banana Flash, Nano Banana 2 Lite, GPT Image 2, and GPT Image 2.5 render at 1K.

How do I get the result?

POST /images/generate returns 202 with an id. GET /creations/{id} then returns the status and result_urls; instead of polling, pass webhook_url and we'll send an event when the image is ready.

Can an AI agent connect Rendergrid?

Yes: an MCP server, skills for Claude Code and Cursor, agents.md and llms.txt — your agent will find the models, prices and request examples on its own. The generate_image tool waits up to 45 seconds for the result; if the image isn’t ready, it returns its id — call get_creation next.

Do you offer terms for high volumes?
