Access & pricing

Prices belong to an endpoint and billing tier. A provider listing does not guarantee access for every account or region.

Haiper API

Provider source (opens in a new tab)
API model ID
Not collected

The route selects an operation/family; an exact checkpoint selector is not documented.

Access
Documented paid API requiring a Haiper API key and top-up. Runtime generation and account eligibility were not tested.
Regions
Deployment regions not established
API endpoint URL
POST https://api.haiper.ai/v1/jobs/text2imageSource for API endpoint URL (opens in a new tab)
Authentication
Authorization: Bearer APIKEY; Content-Type: application/json. Prepaid balance is required.Source for Authentication (opens in a new tab)
Request quotas
Default 500 HTTP requests per minute and 40 concurrent generations; exceeding either yields HTTP 429. Higher quotas require contacting Haiper.Source for Request quotas (opens in a new tab)
Asynchronous generation
Submission returns generation_id. Poll GET /v1/jobs/{creation_id}/status for pending, processing, succeed, failed or post_processing. Fetch GET /v1/creation/{creation_id} after succeed. Polling is not token streaming.Source for Asynchronous generation (opens in a new tab)
Creation privacy
Schema description: is_public defaults to true; set false for private creation. The official ComfyUI node defaults false, so wrapper and API defaults differ.Source for Creation privacy (opens in a new tab)
Seed controls
Generation settings describe seed default -1 without a verified integer range or reproducibility guarantee.Source for Seed controls (opens in a new tab)
Request format
JSON request and response. Nested source-image requirements are sometimes only descriptive in the schema.Source for Request format (opens in a new tab)
Negative prompts
Optional negative_prompt; numeric character ceiling not published.Source for Negative prompts (opens in a new tab)

Caching

Caching can reuse earlier input processing. Availability, lifetime and billing depend on the endpoint. A cache hit still generates a new response.

01 / INITIAL INPUTProcess & retain

The system processes eligible input and retains reusable state.

02 / LATER REQUESTCheck available state

Reuse depends on matching input, session state and the cache policy.

03 / CACHE HITReuse & generate

Reusing state can reduce repeated work. Any charges follow the billing rules below.

What the measurements say

No benchmark observations have been added for this model. We do not turn a vendor description into a performance score.

Latency and throughput depend on the host, request size, reasoning settings and load. There is no measured speed or global usage figure in this record.

The record behind the model

Why it is included

Private hosted-model classification inferred from Haiper naming its own model family and providing hosted access, without a matching public weight release established in reviewed first-party evidence. Exact weight licensing, ancestry and checkpoint architecture remain unresolved. The sample OpenAPI MIT license and public ComfyUI client license are not model weight licenses.
