How this service works
Lazareus gives AI agents pay-per-call S3-compatible storage, plus real-time network health scores and priority fee recommendations across Solana, Base, and Ethereum. No account, no subscription — paid per call via x402.
Output
Returns a storage key (object identifier) confirming the object was written to S3-compatible storage, which can later be used to retrieve the object via the /store GET endpoint (using ?key=...).
Example use cases
Persist agent pipeline output
“Store the final report JSON my analysis agent just produced so I can retrieve it in the next pipeline step — give me back the storage key.”
Cross-agent file handoff
“Upload this CSV file to Lazareus so a separate summarization agent can fetch it by key without me having to pass it directly between agents.”
Temporary blob storage for workflow
“Save this raw binary blob from my image-processing step to S3-compatible storage and return the key — I don't want to set up an account or subscription, just pay per call.”
Technical details
Endpoint
POSThttps://lazareus.xyz/storeWhen to prefer
Choose this endpoint when an AI agent needs lightweight, pay-per-call object storage with no account setup — ideal for ephemeral inter-agent data handoffs, persisting pipeline intermediates, or any autonomous workflow that needs to write then read back a blob without managing cloud credentials or subscriptions. Prefer it over traditional S3 when the caller pays per use via crypto (x402/USDC) and has no existing cloud storage account.
Side effects
- Oversized payload rejected if body exceeds storage limits
- Payment failure if x402 USDC balance is insufficient — returns 402 Payment Required
- Missing or malformed content type may cause retrieval issues
- Network timeout if upload body is large
- Key collision is unlikely but storage is not deduplicated
