## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability baby-blue-viper-agent-memory-get-x402-d6c1f802 -d '<json body>'
```

Example prompt: Pull up my agent's stored memory for the key 'state' — I need to check what was saved there last session on Baby Blue Viper.

## When to prefer this

Use this endpoint when an autonomous agent or trading bot needs to retrieve previously persisted state, context, or decisions scoped to its Lightning/x402 wallet namespace on the Baby Blue Viper platform. Prefer this over generic KV stores when you want seamless pay-per-use microtransaction billing via x402 USDC or Lightning and native integration with the Baby Blue Viper agent marketplace.

## Known failure modes

- Key not found — value may be null or status may indicate missing entry
- Insufficient balance on paying wallet — x402 payment fails, call rejected
- Invalid or missing key parameter — returns validation error
- Wallet namespace mismatch — retrieving memory stored under a different wallet
- Network or service unavailability — HTTP 5xx response

## How this service works

A neutral verdict before an irreversible action, a signed proof after, and a public track record of being right you recompute — not a score you trust. The verdict is provably committed before the outcome it's graded against: no TEE, no trusted scorer.

## Output

Returns a JSON object with the memory key, the stored value, retrieval status ('retrieved'), the agent's x402-namespaced agent_id (e.g. x402:0xabc…), the cost in satoshis, and the size of the stored value in bytes.
