Key-value state for agents that need to survive between calls. Every write carries a time-to-live; the maximum is 30 days and there is no way to store something permanently. Values are opaque JSON up to 64 KB, at most 1000 live keys per namespace. Actions: set, get, list, delete. A get on a missing or expired key answers found=false, it is not an error. The namespace is a plain string chosen by the caller and is not authenticated — anyone who knows it can read it, so do not put secrets in it.
# 1. Ask the endpoint what it costs (no payment, no wallet needed): curl -i -X GET 'https://agent.halowerk.com/v1/state-store' # -> HTTP/1.1 402 Payment Required # the response carries the price, asset and pay-to address. # 2. Pay and retry with any x402 client: npx x402-fetch 'https://agent.halowerk.com/v1/state-store'
