How this service works
Store a secret (credential, token, key) for later retrieval — encrypted at rest (AES-256-GCM). Returns an id + access token; fetch later by id+token. Max 16KB. For agent state that must survive across runs.
Output
Returns a JSON object containing a unique secret ID (e.g. sec_abc123), a one-time access token (e.g. tok_9f2c...), an ok:true confirmation, and a note confirming the value is encrypted at rest with AES-256-GCM. The secret can only be retrieved once using the returned ID and token.
Example use cases
Agent-to-agent credential handoff
“Encrypt and store my database password 'P@ssw0rd!secret' as a one-time-read dead drop, then give me the ID and access token so I can send them to the receiving agent.”
One-time secret share with a contractor
“I need to give a freelancer a sensitive API key just once — can you store 'Bearer eyJhbGci...' as an encrypted dead drop and give me the retrieval token to send them?”
Ephemeral config value for a deploy pipeline
“Store the value 'prod-db-host=db.internal:5432' as an encrypted secret so my CI pipeline can read it exactly once during deployment, and give me the secret ID and token.”
Technical details
Endpoint
POSThttps://pyfile-agent.taile3ff35.ts.net/secret/put?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to pass a sensitive value (API key, password, token) between agents or humans in a one-time-read, zero-persistence manner. It is preferable to plaintext sharing, environment variable hacks, or persistent secret stores when you want the secret to self-destruct after one retrieval. It is pay-per-call at $0.002 USDC, making it cost-effective for individual agent workflows that need ephemeral encrypted storage without managing a full secrets vault.
Side effects
- Missing or malformed request body returns an error
- Payment not provided or insufficient USDC/XNO balance causes a 402 Payment Required response
- Server-side encryption failure may return a 500 error
- Attempting to store an excessively large payload may be rejected
- Network timeout to the Tailscale-hosted endpoint may result in connection errors
