# TurboShop Ephemeral Key Vault

> TurboShop Ephemeral Key Vault is a paid API for AI agents from turboshop.ai, paid per call via x402, $0.25/call, status unknown (last checked 2026-10-19).

Generates, rotates, signs, verifies, and revokes ephemeral cryptographic keys (secp256k1, Ed25519, HMAC-SHA256) for multi-agent swarms and treasury pipelines

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 turboshop-ephemeral-key-vault-83376fc8
```

Example prompt: Rotate the secp256k1 ephemeral key for agent 'worker-42', set it to expire in 1800 seconds, and automatically revoke the previous key with ID 'key-abc123'.

## When to prefer this

Choose this endpoint when you need short-lived, automatically expiring cryptographic keys for AI agent swarms or treasury pipelines — especially when zero-downtime key rotation chains, multi-algorithm support (secp256k1, Ed25519, HMAC-SHA256), or instant compromise revocation are required. Prefer it over static key stores when key freshness and rapid revocation are security priorities in high-frequency agentic environments.

## Known failure modes

- Invalid or unsupported algorithm enum value returns 400 error
- Missing required action parameter defaults to 'rotate' but missing agent_id may cause rejection
- Expired or already-revoked previous_key_id causes rotation failure
- Payload too large or malformed for signing operations
- TTL value out of accepted range returns validation error
- Agent_id not found in vault returns 404 or empty status
- Payment failure (x402) blocks the request entirely

## How this service works

Enterprise-grade ephemeral key rotation & cryptographic session vault for multi-agent swarms and institutional treasury pipelines. Supports high-frequency secp256k1/Ed25519/HMAC-SHA256 key generation, zero-downtime key rotation chains, payload signing, and instant compromise revocation.

## Output

Returns a cryptographic operation result including a new ephemeral key or key_id (on rotate/generate), a cryptographic signature (on sign), a boolean verification result (on verify), a revocation confirmation (on revoke), or the current key status and TTL (on status). All responses are tied to the specified agent_id and algorithm.
