The API reference on this page shows the request schema, response schema, authentication requirements, and runnable examples for the configured endpoint. ## Before you start Use the DeerAPI base URL and pass your API Key in the `Authorization` header: ```text theme={null} https://api.deerapi.com ``` ```text theme={null} Authorization: Bearer $DEERAPI_KEY ``` ## Model selection Choose a current model ID from the [live pricing page](https://api.deerapi.com/pricing). Model availability changes over time, so avoid copying a model ID from an old project without checking the live list first. ## Implementation notes * Use the OpenAPI playground for the exact request fields accepted by this endpoint. * Keep API Keys on the server side when you build production applications. * Log the request ID from failed calls so support can investigate the request. * Retry `429`, `500`, and `503` responses with exponential backoff. ## OpenAPI ````yaml /api/openapi/image/flux/post-create-task-replicate.openapi.json POST /replicate/v1/models/{models}/predictions openapi: 3.1.0 info: title: Create Predictions - General API version: 1.0.0 description: >- Create a Replicate-style prediction on DeerAPI and receive a prediction id for later polling. servers: - url: https://api.deerapi.com security: - bearerAuth: [] paths: /replicate/v1/models/{models}/predictions: post: summary: Create a Replicate prediction description: >- Submit a prediction request using a model id in the path and a provider-specific `input` object in the body. operationId: create_predictions_general parameters: - name: models in: path required: true description: >- Replicate model id, for example `black-forest-labs/flux-schnell` or `black-forest-labs/flux-kontext-pro`. schema: type: string requestBody: required: true content: application/json: schema: type: object required: - input properties: input: type: object description: >- Provider-specific model input.
