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 value stored at the specified key within the caller's namespace (scoped to the paying wallet or ak_ account key). The value was client-side encrypted before storage, so the agent receives the encrypted blob or, if using the SDK, the decrypted value. Returns a 404-equivalent if the key does not exist.
Example use cases
Retrieve agent session state
“Fetch the value I stored earlier under key 'session-context-7842' in AgentKV so I can resume where I left off.”
Load saved agent configuration
“Read my agent's configuration from AgentKV at key 'agent-config-prod' — I need the settings I wrote there last week.”
Check stored API credential
“Pull the encrypted API token I saved in AgentKV under the key 'stripe-key-v2' so I can use it for this workflow.”
Technical details
Endpoint
GEThttps://api.agentx402.ai/v1/kv/smoke-1785130642When to prefer
Choose this endpoint when an AI agent needs to read back data it previously stored in a persistent, encrypted, per-agent namespace without any signup or API key — ideal for stateless agent workflows that need cross-session memory, credential storage, or configuration retrieval, paid via x402 micropayments. Prefer this over traditional KV stores (Redis, DynamoDB) when operating in a wallet-native, no-auth-setup environment.
Side effects
- Key not found — returns error if the key has never been written or was deleted
- Payment failure — x402 micropayment of $0.003 USDC rejected or insufficient balance causes request to fail
- Wrong namespace — if the wallet or ak_ key used differs from the one that wrote the value, access is denied
- Decryption failure — if the client-side encryption key is lost or mismatched, the raw ciphertext is unreadable
- Rate limits or credit exhaustion — prepaid credits depleted returns an error before serving the request
