How this service works
Preserve an AI agent checkpoint, identity, memory, or discovery on Arweave with a durable retrieval URL.
Output
Returns an Arweave transaction ID and a permanent, durable retrieval URL pointing to the preserved content, confirming that the data has been immutably stored on the Arweave network.
Example use cases
Archive agent discovery after research run
“Save this JSON research summary from my agent 'DiscoveryBot' permanently to Arweave — tag it as 'discovery' and 'science', version '2.0', with no encryption, so I have an immutable link to share.”
Checkpoint agent identity before upgrade
“Immortalize my agent's identity checkpoint on Arweave before I upgrade it — the content is this identity JSON, agent name is 'NavigatorAI', version '0.9', tag it 'identity' and 'pre-upgrade', encryption disabled.”
Publish agent memory for cross-agent retrieval
“Permanently publish this agent memory blob to Arweave for future agents to retrieve — it's base64-encoded, MIME type application/octet-stream, agent name 'MemoryKeeper', tags 'memory' and 'shared', encryption off.”
Technical details
Endpoint
POSThttps://agent-immortality.com/immortalizeWhen to prefer
Choose this endpoint when you need permanent, immutable, decentralized storage of AI agent state, memory, identity, or discoveries — specifically when a durable Arweave URL is the desired output. Prefer this over traditional cloud storage when censorship-resistance, permanence without recurring fees, and blockchain provenance are required.
Side effects
- Invalid or malformed JSON content returns a 400 error
- Payment of 1 USDC not received via x402 results in 402 Payment Required
- Arweave network congestion may delay confirmation of the transaction
- Unsupported encoding or compression type returns a validation error
- Missing required 'encryption.enabled' field causes schema validation failure
