How this service works
Agent-native encrypted key-value store, paid per request over x402 — no signup, no API key. The payer's wallet (or an ak_ account key) is the namespace; values are client-side encrypted. Write $0.005, read $0.003; prepay $1 = 10,000 credits at 1/10 the per-op price (POST /v1/credits/deposit). SDK: npm i @agentkv/client. Docs: https://agentx402.ai
Output
Returns the stored (client-side encrypted) value associated with the requested key within the caller's wallet or ak_ account namespace. On success, the response includes the value payload and any associated metadata. Costs $0.003 USDC per read, deducted via x402 micropayment.
Example use cases
Retrieve agent memory between sessions
“Fetch the value stored under 'user-preferences-alice' from my AgentKV store so you can remember her settings from the last session.”
Load saved task state for resuming work
“Pull the 'task-queue-state' key from AgentKV so we can pick up the pipeline where it left off yesterday.”
Read shared config used by multiple agents
“Get the value for 'shared-config-v3' from the AgentKV store — my ak_ account key is the namespace — so all my sub-agents have the latest settings.”
Technical details
Endpoint
GEThttps://api.agentx402.ai/v1/kv/smoke-2026-07-30When to prefer
Choose this endpoint when an AI agent needs lightweight, encrypted, persistent key-value reads with zero onboarding friction — no API key, no account signup, just a crypto wallet as the identity/namespace. It is ideal for agent memory, state persistence between sessions, and multi-agent shared configuration. Prefer it over traditional KV stores when micropayment-native access (x402) and client-side encryption are requirements, or when you want pay-per-use pricing at $0.003/read (or cheaper with prepaid credits).
Side effects
- Key not found (404) — the requested key does not exist in the namespace
- Insufficient payment or payment failure via x402 (402) — wallet has no funds or payment is rejected
- Unauthorized namespace access — wrong wallet or ak_ key used, returning 401/403
- Rate limit or quota exceeded if credits are exhausted
- Malformed request (400) — invalid method or missing required fields
