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.
Example use cases
Zero-downtime key rotation for agent fleet
“Rotate the Ed25519 ephemeral key for agent 'swarm-node-7', carry over from previous key 'key-xyz789', and set the new key to live for 3600 seconds — make sure the old one is revoked automatically.”
Sign treasury transaction payload
“Sign this payload 'transfer:0xABC:500USDC' using an HMAC-SHA256 ephemeral key for agent 'treasury-bot-1' with a 900-second TTL.”
Instant compromise revocation
“Immediately revoke the secp256k1 key for agent 'compromised-worker-3' — I think it's been exposed and I need to kill access right now.”

Endpoint
GEThttps://turboshop.ai/api/v1/products/prod-ephemeral-key-vault-enterprise/buy?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
