How this service works
File storage for AI agents and ENS names. Upload via MCP, REST, or CLI. Free CDN tier. Permanent Arweave and IPFS options.
Output
Returns a JSON object containing the IPFS URI (e.g. ipfs://bafybei…), the number of bytes stored, and a human-readable permalink URL formed as https://ens.objekt.sh/{name}/blob/{key} for public CDN access.
Example use cases
Agent credential attestation storage
“Save this signed credential JSON under my ENS name vitalik.eth with the key credential.json on objekt.sh so I can share a permanent IPFS link with verifiers.”
AI-generated report publishing
“Take the market analysis report my agent just produced and upload it to objekt.sh under agent.eth with the key report-2024-q4.md — I need a CDN permalink to share.”
Proof file pinned to ENS identity
“Upload this Twitter proof file to objekt.sh under myname.eth with the key proof.twitter and give me back the IPFS URI and permalink.”
Technical details
Endpoint
PUThttps://api.objekt.sh/%7Bname%7D/blob/%7Bkey%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to store a file under a specific ENS identity namespace with a stable, human-readable permalink, especially when permanent decentralized storage on IPFS or Arweave is required. Prefer it over generic S3-style storage when ENS-linked identity, censorship resistance, or IPFS compatibility matters. It is particularly suited to AI agents that need to publish outputs, proofs, or credentials tied to a Web3 identity.
Side effects
- Invalid or unresolvable ENS name returns a 4xx error
- Blob key contains illegal characters causing a routing failure
- Payment of 0.25 USDC not attached results in 402 Payment Required
- File too large for the tier causes a 413 or quota error
- Network timeout during upload leaves the blob in an inconsistent state
- Arweave/IPFS pinning backend unavailable returns a partial or degraded response
