Call {function} using the short-path invoke endpoint without a date prefix.
GET /2015-03-31/functions List Lambda functions with their configuration · Aws Lambda List Functions #
Ask an LLM
“What Lambda functions do I have in this AWS Region?”
“Can I include every published version of each function when listing them, not just $LATEST?”
Tell an agent
List my Lambda functions, {max} per page, on the 2015-03-31 API.
List all functions including every published version by setting FunctionVersion to {function_version}.
POST /2015-03-31/functions Create a Lambda function from a deployment package · Aws Lambda Create a Function #

DELETE /2015-03-31/functions/{FunctionName} Delete a Lambda function or one of its versions · Aws Lambda Delete a Function #
Ask an LLM
“Does deleting a Lambda function also remove all its versions and aliases?”
“Can I delete just one published version of a function and keep the rest?”
Tell an agent destructive · confirm first
Delete Lambda function {function} with all of its versions and aliases using the 2015-03-31 endpoint.
Delete only version {qualifier} of function {function}.
GET /2015-03-31/functions/{FunctionName}/configuration Get a function's runtime and resource settings · Aws Lambda Get Function Configuration #
Ask an LLM
“What runtime, memory size and timeout is my function configured with?”
“Where can I check a function's handler, role, VPC settings and code SHA-256 without downloading the code?”
Tell an agent
Show the configuration settings (runtime, memory, timeout, role) of function {function}.
Get the version-specific configuration of function {function} for {qualifier}.
PUT /2015-03-31/functions/{FunctionName}/configuration Change a function's memory, timeout or environment · Aws Lambda Update Function Configuration #
Ask an LLM
“How do I raise the memory or timeout on an existing Lambda function?”
“Can I change environment variables or attach layers to a function without redeploying its code?”
Tell an agent
