Amazon Bedrock Runtime

Technical Preview

Overview

Client-mode REST API connectors for Amazon Bedrock: triage alarms and summarize shift logs with the Converse API, create Titan embeddings with InvokeModel, count tokens, screen text with a guardrail, and list foundation models and inference profiles, all with a Bedrock API key. This is one of the templates in the Amazon Bedrock REST API app (amazon-bedrock). Deploy it alongside the other connectors of that app when they depend on each other (for example a token connector plus an API connector).

Auth

Amazon Bedrock API key as Authorization: Bearer {value.json.api_key} (long-term ABSK…, short-term bedrock-api-key-…). Hub secret suggested AWS_BEARER_TOKEN_BEDROCK + GET SECRET. Alternative: AWS SigV4 (service bedrock) computed outside the broker, documented in comments. Never commit keys. Auth headers used by the template: Authorization: Bearer {value.json.api_key}.

Template parameters

Placeholder	Type	Description	Required
`RouteName`	string	Name of the Amazon Bedrock Runtime connector	no
`BaseUrl`	string	Amazon Bedrock Runtime base URL without trailing slash (e.g. https://bedrock-runtime.eu-west-1.amazonaws.com)	yes

BASE_ADDRESS default: https://bedrock-runtime.eu-west-1.amazonaws.com.

Deploy

Get the template card (JSON with template and metadata) from the broker, then deploy the connector:

mosquitto_pub -t '$SYS/Coreflux/Command' -m "-connectorCode AMAZON_BEDROCK_RUNTIME"

The deployable connector from the REST API app, with BASE_ADDRESS already filled in:

DEFINE CONNECTOR AmazonBedrockRuntime WITH TYPE REST_API
    ADD REST_API_CONFIG
        WITH BASE_ADDRESS "https://bedrock-runtime.eu-west-1.amazonaws.com"

    ADD EVENT CountTokens
        WITH SOURCE_TOPIC "ai/bedrock/tokens/count"
        WITH DESTINATION_TOPIC "ai/bedrock/tokens/count/response"
        WITH METHOD "POST"
        WITH ENDPOINT "/model/{value.json.model_id}/count-tokens"
        WITH HEADERS
            ADD "Accept" "application/json"
            ADD "Content-Type" "application/json"
            ADD "Authorization" "Bearer {value.json.api_key}"
        WITH BODY "{value.json.body}"
    ADD EVENT ApplyGuardrail
        WITH SOURCE_TOPIC "ai/bedrock/guardrail/apply"
        WITH DESTINATION_TOPIC "ai/bedrock/guardrail/apply/response"
        WITH METHOD "POST"
        WITH ENDPOINT "/guardrail/{value.json.guardrail_id}/version/{value.json.guardrail_version}/apply"
        WITH HEADERS
            ADD "Accept" "application/json"
            ADD "Content-Type" "application/json"
            ADD "Authorization" "Bearer {value.json.api_key}"
        WITH BODY "{value.json.body}"

Deploy it with -addConnector (do not include ADD METADATA).

Usage example

Call Converse by publishing a JSON payload to its request topic, and read the reply on the response topic:

mosquitto_sub -t 'ai/bedrock/converse/send/response' &
mosquitto_pub -t 'ai/bedrock/converse/send' -m '{"api_key": "<api_key>", "body": {}, "model_id": "<model_id>"}'
