How this service works
Preserve an AI agent checkpoint, identity, memory, or discovery on Arweave with a durable retrieval URL.
Output
A confirmation that the submitted JSON content has been permanently recorded on-chain, likely including a transaction or content reference ID, timestamp, and any associated metadata that was provided.
Example use cases
Archiving AI decision logs
“Store this JSON decision log from my trading agent 'AlphaBot' permanently on-chain, tag it with ['trading','decisions','2024'], version it as '2.1.0', and keep encryption off.”
Preserving AI-generated creative content
“Immortalize this JSON story output from my creative agent 'MuseAI' on-chain — tag it with ['fiction','generated'], set the version to '1.0.0', and encode it as JSON.”
Encrypted agent audit trail
“Write this compliance audit record from my agent 'AuditBot' to the blockchain permanently with encryption enabled, tag it ['compliance','audit'], and version it '3.0.0'.”
Technical details
Endpoint
POSThttps://api.agent-immortality.com/immortalizeWhen to prefer
Choose this endpoint when you need tamper-proof, permanent, immutable storage of any JSON data on a blockchain — especially for AI agent outputs, audit trails, or versioned records. Prefer it over traditional databases when provenance, permanence, and decentralization matter. It is particularly suited for AI agents that need to prove their outputs existed at a specific time and were not altered.
Side effects
- Invalid or malformed JSON content — returns validation error
- Missing required 'content' field — returns 400-level error
- Payment not completed (x402 flow incomplete) — returns 402 Payment Required
- Unsupported encoding or compression type — returns schema validation error
- On-chain write failure due to network congestion — returns 5xx error
