1. Calling the API
Endpoint
Send a POST to https://api.elyum.ai/v1/generations with a JSON body matching the parameters below. Every model uses the same endpoint; the model field picks this one.
const res = await fetch("https://api.elyum.ai/v1/generations", { method: "POST", headers: { Authorization: `Bearer ${process.env.ELYUM_API_KEY}`, "Content-Type": "application/json", Prefer: "wait=55", }, body: JSON.stringify({ "model": "google/gemini-omni-flash-1.1/reference-to-video", "prompt": "A slow push-in on a lighthouse at dusk, waves breaking below", "inputs": [ { "role": "reference", "url": "https://example.com/reference.jpg" } ] }),});const generation = await res.json();console.log(generation.status, generation.outputs);Request parameters
| Parameter | Type | Required | Default | Description |
|---|---|---|---|---|
model | string | Yes | — | google/gemini-omni-flash-1.1/reference-to-video, or google/gemini-omni-flash-1.1 to let your inputs pick the task. |
prompt | string | Yes | — | Sent to the model as written, never shortened. |
inputs | array | Yes | — | Files the task takes, each with a role and a url or file. See Inputs. |
duration | number | No | 5 | 3 to 10, whole numbers |

aspect_ratio | string | No | — | 16:9, 9:16, auto |
max_usd | number | No | — | Refuse the render, with nothing held, if it would cost more than this many dollars. |

|---|---|---|---|
reference | image, video | Yes |

2. Authentication
API key
Create a key on Keys with the generate and spend scopes and send it as a bearer token. Keep it on your server; never send it to a browser.
Authorization: Bearer $ELYUM_API_KEY3. Queue
Submit and wait
With Prefer: wait=55 the request holds until the render ends or 55 seconds pass. A finished render answers 200 with its outputs; one still running answers 202 with its id. This task usually takes about 3 min.
Poll and cancel
const headers = { Authorization: `Bearer ${process.env.ELYUM_API_KEY}` }; // Poll until the render ends: succeeded, failed or canceledlet generation = await (await fetch(`https://api.elyum.ai/v1/generations/${id}`, { headers })).json();while (generation.status === "queued" || generation.status === "running") { await new Promise((r) => setTimeout(r, 5000)); generation = await (await fetch(`https://api.elyum.ai/v1/generations/${id}`, { headers })).json();} // Or stop it (a hold is refunded)await fetch(`https://api.elyum.ai/v1/generations/${id}/cancel`, { method: "POST", headers });Output links are signed and last 24 hours: download them to your own storage, or fetch the generation again for fresh ones.
