• validate.entity - Validate entity against constraints
• validate.json_schema - Validate data against JSON schema

Transaction Operations

• txn.begin - Begin a transaction
• txn.commit - Commit a transaction
• txn.abort - Abort a transaction

Key-Value Store Operations

• kv.get - Get value from KV store
• kv.put - Put value into KV store
• kv.cas_put - Compare-and-swap put (conditional)
• kv.delete - Delete from KV store

Blob Store Operations

• blob.get - Get blob from store
• blob.put - Put blob into store
• blob.verify_digest - Verify blob integrity

Index Operations

• index.query - Query an index
• index.upsert - Insert or update index entry
• index.delete - Delete from index

Cache Operations

• cache.get - Get from cache
• cache.put - Put into cache

Proxy Operations

• proxy.fetch - Fetch from upstream proxy

Response Operations

Usage

Copy a template file and customize it for your needs. Templates use placeholders that should be replaced:

• {namespace} - Package namespace
• {name} - Package name
• {version} - Package version
• {variant} - Package variant
• $variable - Runtime variable from pipeline execution

Example

To create a new route based on a template:

cp templates/route_template.json my_route.json
# Edit my_route.json with your route definition
# Use the admin API to add the route to the system
