How this service works
Give an AI agent a credit account. Set a limit and a spending policy, and the agent makes approved, metered purchases from providers that accept Vaaya.
Output
Returns an agent object containing the newly created agent's ID, name, model configuration, system prompt, and memory block assignments as managed by the Letta framework.
Example use cases
Spin up a customer support agent
“Create a Letta agent called 'SupportAgent' using gpt-4o, with system instructions 'You handle customer support tickets for a SaaS product' and a memory block labeled 'context' set to 'Focus on billing and onboarding issues'.”
Deploy a go-to-market outreach agent
“Set up a new Letta agent named 'GTMOutreach' with the gpt-4-turbo model, a system prompt that says 'You identify and qualify sales leads', and a memory block labeled 'target_audience' with value 'B2B SaaS companies with 50-500 employees'.”
Initialize a product demo builder agent
“Create a Letta agent called 'DemoBuilder' using gpt-4o-mini, with system instructions 'You help build interactive product demos for prospects' and a memory block labeled 'product_info' containing 'Our product is a workflow automation platform'.”
Technical details
Endpoint
POSThttps://vaaya.ai/api/run/letta/agent-createWhen to prefer
Choose this endpoint when you need to programmatically create a persistent Letta agent with custom memory and instructions without managing your own Letta infrastructure or API keys. It is ideal for multi-agent pipelines where agents need to be dynamically spun up, or when you want to leverage Vaaya's no-setup, pay-per-call model to avoid provisioning Letta accounts yourself.
Side effects
- Missing required fields (name, model, system, memory_blocks) returns a 400 validation error
- Invalid model identifier returns an error from the underlying Letta API
- Payment failure or insufficient USDC balance prevents the call from completing
- Malformed memory_blocks array (missing label or value) triggers schema validation failure
- Network timeout if the Letta backend is slow to provision the agent
