How this service works
Export your whole memory as one signed JSON document (format port402-memory-export/1, sha256 + Ed25519 integrity block).
Output
A single JSON document formatted as port402-memory-export/1 containing all key-value pairs stored under the calling wallet's memory namespace, along with a sha256 hash and an Ed25519 signature block that allows any recipient to verify the document's authenticity and integrity.
Example use cases
Audit agent memory before deployment
“Before I deploy my agent to production, can you pull a full signed export of its entire memory store so I can audit everything it has saved and verify nothing unexpected is in there?”
Back up persistent memory for disaster recovery
“I want a cryptographically signed backup of my agent's entire memory namespace right now — export it as a single JSON document I can store safely offline.”
Transfer memory to a new agent instance
“I'm spinning up a new agent and need to migrate all the stored data from the old one. Can you export the complete signed memory snapshot so I can import it into the new instance?”
Technical details
Endpoint
GEThttps://port-402-production.up.railway.app/v1/export?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a complete, portable, and cryptographically verifiable snapshot of all stored agent memory in one atomic operation. Prefer this over listing keys individually when you need a full backup, audit trail, migration artifact, or integrity-provable archive of the entire namespace. Its Ed25519 + sha256 integrity block makes it ideal for scenarios where tamper-evidence matters.
Side effects
- Empty memory namespace returns a document with no entries but still a valid signed structure
- Invalid or missing x402 payment results in 402 Payment Required response
- Wallet with no stored keys returns an empty but validly signed export
- Network timeout on Railway infrastructure may cause transient failures
