Send the key in the x-api-key header or as Authorization: Bearer; keys start with leap_. > Take model IDs and input schemas from GET /v1/models/{creator}/{name}, or from https://api.tryleap.ai/v1/public/models without a key. Never guess an input field: unknown fields are a 400. > Model inputs take uploaded file IDs (file_...), never URLs. > To give a coding agent the whole API, install the Leap skill: curl -fsSL https://www.tryleap.ai/install.sh | sh > The full OpenAPI 3.1 spec is at https://www.tryleap.ai/docs/openapi.json. # Start a video or sound upload > The first of three steps for a video or a sound: this answers with a URL. `PUT` the file's bytes there with exactly `upload_headers` within the hour, then complete the upload. Up to 1 GB of video (MP4, MOV, WebM) or 500 MB of audio (MP3, WAV, M4A), and up to 4 hours long. Needs credit on your balance. A workspace can upload 5 GB a day, with 10 uploads in flight at once. Needs an API key with the `generations:write` scope. ## OpenAPI ````yaml /openapi.json post /v1/uploads openapi: 3.1.0 info: title: Leap API version: 1.0.0 description: >- One API for the best image, video and audio models.
