MCP
Or let your agent call it.
Leap's MCP server lets Claude Code, Claude, VS Code and other MCP clients run Recraft Crisp Upscale, read its inputs and fetch the result, on your balance. Signing in happens in the browser, so there is no key to paste.

Questions
Recraft Crisp Upscale API questions
- How much does the Recraft Crisp Upscale API cost?
- An image costs $0.007. That is the provider's list price plus our margin, the same as in the studio. POST /v1/quotes prices any input for free before you run it.
- Can I try the Recraft Crisp Upscale API for free?
- No. API keys run on paid credit, so a key's first call needs a top-up, and quotes are free. An image costs $0.007. A first top-up of $5, with no fee, covers 714 default calls.
- Do I pay for calls that fail?
- No. The price is held when a call starts and charged only if it succeeds. A call that fails, or that the model's safety filter refuses, comes back with status "failed" and a failure_cause, and the hold is released.
- Is this Recraft's own API?
- No. Leap is a separate service: it sends your call to Recraft's model and gives you what it makes, so you need no Recraft account. One Leap key runs Recraft Crisp Upscale and every other model in the catalog, from one balance.
- What are the rate limits?
- 600 requests a minute per API key and 300 a minute per IP address. A batch starts up to 50 calls in one request. A 429 says how long to wait in its Retry-After header.
- Can an AI agent call it?
- Yes. Leap's MCP server lets Claude Code, Claude, VS Code and other MCP clients find Recraft Crisp Upscale, read its inputs, run it and fetch the result on your balance. The client signs you in through the browser, so there is no key to paste.
