Complete reference for using the AICR API Server.

Overview

The AICR API Server provides HTTP REST access to recipe generation and bundle creation for GPU-accelerated infrastructure. Use the API for programmatic access to configuration recommendations and deployment artifacts.

Version numbers in the sample requests and responses below (server version, chart versions, driver versions) are illustrative. The authoritative, current versions are in the Component Catalog and the Container Images BOM.

API vs CLI

Use the API for remote recipe generation and bundle creation
Use the CLI for local operations, snapshot capture, and ConfigMap integration

Feature	API	CLI
Recipe generation	✅ GET /v1/recipe	✅ `aicr recipe`
Value query	✅ GET /v1/query	✅ `aicr query`
Bundle creation	✅ POST /v1/bundle	✅ `aicr bundle`
Snapshot capture	❌ Use CLI	✅ `aicr snapshot`
ConfigMap I/O	❌ Use CLI	✅ `cm://` URIs
Agent deployment	❌ Use CLI	✅ `aicr snapshot`

Base URL

Local development (example):

http://localhost:8080

Start the local server:

docker pull ghcr.io/nvidia/aicrd:latest
docker run -p 8080:8080 ghcr.io/nvidia/aicrd:latest

Quick Start

Get a Recipe

Generate an optimized configuration recipe for your environment:

# GET: Basic recipe for H100 on EKS (query parameters)

    -H "Content-Type: application/json" -d @- -o bundles.zip

# Extract the bundles
unzip bundles.zip -d ./bundles

metadata.excludedOverlays is optional. When present, each entry includes the overlay name and a machine-readable reason such as constraint-failed or mixin-constraint-failed.

GET /v1/query

Query a specific value from a fully hydrated recipe. Resolves a recipe from criteria (same parameters as GET /v1/recipe), merges all base, overlay, and inline overrides, then returns the value at the given selector path.

Query Parameters:

All GET /v1/recipe parameters are supported, plus:

Parameter	Type	Required	Description
`selector`	string	Yes	Dot-delimited path to the value to extract (e.g. `components.gpu-operator.values.driver.version`). Empty string returns the entire hydrated recipe.

Response:

Scalar values (string, number, bool) are returned as plain JSON values
Complex values (maps, lists) are returned as JSON objects/arrays

Examples:

# Get a specific Helm value
curl -s "http://localhost:8080/v1/query?service=eks&accelerator=h100&intent=training&selector=components.gpu-operator.values.driver.version"

# Get deployment order
curl -s "http://localhost:8080/v1/query?service=eks&accelerator=h100&intent=training&selector=deploymentOrder" | jq '.'

# Get a component subtree
curl -s "http://localhost:8080/v1/query?service=eks&accelerator=h100&selector=components.gpu-operator.values.driver" | jq '.'

POST /v1/bundle

Generate deployment bundles from a recipe.

Query Parameters:

Parameter	Type	Default	Description
`bundlers`	string	(all)	Comma-delimited list of bundler types to execute
`set`	string[]		Value overrides (format: `bundler:path.to.field=value`). Repeat for multiple.
`dynamic`	string[]		Declare value paths as install-time parameters (format: `component:path.to.field`). Repeat for multiple. Supported with `deployer=helm`, `deployer=argocd-helm`, `deployer=flux`, and `deployer=helmfile`.
`system-node-selector`	string[]		Node selectors for system components (format: `key=value`). Repeat for multiple.
`system-node-toleration`	string[]		Tolerations for system components (format: `key=value:effect`). Repeat for multiple.
`accelerated-node-selector`	string[]		Node selectors for GPU nodes (format: `key=value`). Repeat for multiple.
`accelerated-node-toleration`	string[]		Tolerations for GPU nodes (format: `key=value:effect`). Repeat for multiple.
`nodes`	int	0	Estimated number of GPU nodes (0 = unset). Written to Helm value paths declared in the registry under `nodeScheduling.nodeCountPaths`.
`vendor-charts`	bool	false	Pull upstream Helm chart bytes into the bundle at bundle time so the artifact is fully self-contained and air-gap deployable. Each vendored chart is recorded in `provenance.yaml` with name, version, source URL, and SHA256. Trades the upstream CVE-yank fail-loud signal for offline deployability — see the CLI reference's "Vendoring Charts for Air-Gap" section for the full tradeoff. Requires the `helm` binary on the API server's `$PATH` and registry credentials configured for any private upstream repos (`HELM_REPOSITORY_USERNAME`/`HELM_REPOSITORY_PASSWORD` for HTTP(S); docker config for OCI). If prerequisites are missing the request fails with HTTP 500 and a structured error code (`UNAVAILABLE` for missing helm, `UNAUTHORIZED` for credentials).
`deployer`	string	helm	Deployment method: `helm`, `argocd`, `argocd-helm`, `flux`, or `helmfile`
`repo`	string		Git repository URL for GitOps deployments (used with `deployer=argocd` and `deployer=flux`; ignored by `deployer=argocd-helm`)
`app-name`	string		Parent Argo Application name (default: `aicr-stack` for `deployer=argocd-helm`, `nvidia-stack` for `deployer=argocd`). Must be a DNS-1123 subdomain. Required when deploying multiple non-overlapping AICR bundles to the same Argo CD namespace so the parent Applications do not collide. For `deployer=argocd-helm`, the value is the chart default and can still be overridden at install time via `helm install --set appName=...`. Rejected with HTTP 400 on other deployers.

Request Body:

The request body is the recipe (RecipeResult) directly. No wrapper object needed.

# Response headers:
# X-RateLimit-Limit: 100
# X-RateLimit-Remaining: 95

When rate limited (HTTP 429), use the Retry-After header:

# Retry with backoff
response=$(curl -s -w "%{http_code}" "http://localhost:8080/v1/recipe?accelerator=h100")
if [ "${response: -3}" = "429" ]; then
  retry_after=$(curl -sI "http://localhost:8080/v1/recipe" | grep -i "Retry-After" | awk '{print \$2}')
  echo "Rate limited. Retrying after ${retry_after}s..."
  sleep "$retry_after"
fi

Rate Limiting

Limit: 100 requests per second per IP
Burst: 200 requests
Headers: X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Reset
429 Response: Includes Retry-After header

Criteria Allowlists

The API server can be configured to restrict which criteria values are allowed. This enables operators to limit the API to specific accelerators, services, intents, or OS types.

Configuration

Allowlists are configured via environment variables when starting the server:

Environment Variable	Description	Example
`AICR_ALLOWED_ACCELERATORS`	Comma-separated list of allowed GPU types	`h100,l40`
`AICR_ALLOWED_SERVICES`	Comma-separated list of allowed K8s services	`eks,gke`
`AICR_ALLOWED_INTENTS`	Comma-separated list of allowed workload intents	`training`
`AICR_ALLOWED_OS`	Comma-separated list of allowed OS types	`ubuntu,rhel`

Behavior:

If an environment variable is not set, all values for that criteria are allowed
If an environment variable is set, only the specified values are permitted
The any value is always allowed regardless of allowlist configuration
Allowlists apply to both /v1/recipe and /v1/bundle endpoints

Example Configuration

# Start server allowing only H100 and L40 GPUs on EKS
docker run -p 8080:8080 \
  -e AICR_ALLOWED_ACCELERATORS=h100,l40 \
  -e AICR_ALLOWED_SERVICES=eks \
  ghcr.io/nvidia/aicrd:latest

Common Issues

"Invalid accelerator type" error:

# Use valid values: h100, h200, gb200, b200, a100, l40, rtx-pro-6000, any
curl "http://localhost:8080/v1/recipe?accelerator=h100"

"Recipe is required" error:

# Ensure recipe is in request body
curl -X POST "http://localhost:8080/v1/bundle" \
  -H "Content-Type: application/json" \
  -d '{"recipe": {...}}'  # recipe must not be null

Empty zip file:

# Check recipe has componentRefs
curl -s "http://localhost:8080/v1/recipe?accelerator=h100" | jq '.componentRefs'

Connection refused (local):

# Start local server first
make server
