Everything you need for intelligent agents
From simple chatbots to complex reasoning agents — build it all with a single API.
Custom AI Agents
Create agents with a system prompt that defines their personality and expertise. Each agent gets its own chat endpoint.
Persistent Memory
Agents remember past conversations using Voyage AI embeddings. Context-aware responses that improve over time.
Multi-Step Reasoning
Enable reasoning for complex tasks. Agents think step-by-step before responding for deeper analysis.
Pay-Per-Use
Deposit USDC on Base L2. Pay only for what you use — $1 to create an agent, then per-token for chat.
On-Chain Billing
Every transaction is recorded in a transparent ledger. Full audit trail of deposits, charges, and usage.
Simple API
Create an agent and start chatting in two API calls. Powered by Venice.ai private inference.
