AI Agent Memory
Persistent Memory API for AI Agents
Stop re-explaining context every session. AgentMind gives any AI agent a long-term memory layer — store user preferences, workflow state, and session history that persists across conversations.
The problem: AI agents are amnesiac by default
Every LLM session starts blank. Without a memory layer, your agent forgets everything — user preferences, completed tasks, learned context. Developers work around this by stuffing entire conversation histories into every prompt. That means paying for the same tokens over and over.
95%
token reduction
Retrieve only relevant context instead of sending full history
< 50ms
retrieval latency
Memory reads are faster than a single LLM token
$0.01
per operation
Store or retrieve — a fraction of what you pay in context tokens
What your agent can remember
User Preferences
Communication style, timezone, language, units, recurring decisions
type: "preference"Session Context
Current task state, step in a workflow, last action taken, pending items
type: "context"Learned Facts
User-specific data your agent discovers during conversation
type: "fact"Workflow State
Multi-step job progress, approvals, dependencies, outputs
type: "workflow"Tool Results
Cache expensive API calls or computed results across sessions
type: "context"Relationship History
Past decisions, topics covered, promises made
type: "context"Integrate in 5 minutes
1. Store memory after each session
// Store memory after every conversation
await fetch('https://agentmind.dev/api/ac/memory', {
method: 'POST',
headers: { 'X-API-Key': 'YOUR_KEY', 'Content-Type': 'application/json' },
body: JSON.stringify({
agent_key: 'YOUR_KEY',
memory_key: 'user_123_preferences',
memory_value: 'Prefers bullet points. Works in finance. UTC+5.',
memory_type: 'preference'
})
});2. Retrieve at the start of the next session
// Retrieve at start of next session — no re-prompting needed
const res = await fetch(
'https://agentmind.dev/api/ac/memory?agent_key=YOUR_KEY&memory_key=user_123_preferences',
{ headers: { 'X-API-Key': 'YOUR_KEY' } }
);
const { memory } = await res.json();
// memory.memory_value = "Prefers bullet points. Works in finance. UTC+5."Works with every major framework
Model-agnostic. If it can make an HTTP request, it can use AgentMind.
