How this service works
Pay-per-call x402 execution primitives (USDC on Base). Code execution runs in isolated Cloudflare Dynamic Worker sandboxes (JavaScript + Python, network blocked). Web search backed by Bing RSS. Self-hosted facilitator.
Output
Returns a JSON object with a 'data' field containing the stored or retrieved value, a 'success' boolean indicating whether the operation succeeded, and a 'receipt_id' UUID confirming the paid transaction.
Example use cases
Multi-step agent workflow state persistence
“Save the current conversation context and decision tree state to a remote KV store between each agent step — I need to pick up exactly where I left off if the workflow restarts.”
Temporary cache for expensive computation results
“After my agent finishes a costly calculation, store the result in a pay-per-call KV store so other agent instances can reuse it without recalculating.”
Cross-agent configuration and secret sharing
“My fleet of agents needs to read shared API keys and configuration settings from a lightweight remote store — I don't want to hard-code them or pay for a full database subscription.”
Technical details
Endpoint
POSThttps://api.zuluworksai.com/exec/kv-storeWhen to prefer
Choose this endpoint when your agent needs lightweight, ephemeral or persistent key-value storage on a true pay-per-call basis with no subscription, and you are already operating within the x402/Base USDC micropayment ecosystem. Ideal for stateless agent workflows that need to persist small data blobs between steps without provisioning a full database.
