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 Arweave or IPFS URI (ar://... or ipfs://...), the MIME type (kind), the ENS name the file is associated with, the file size in bytes, a human-readable permalink URL (e.g. https://ar.objekt.sh/...), and the EIP-1577 contenthash hex string suitable for setting on an ENS record.
Example use cases
AI agent saves generated artwork permanently
“I just generated a PNG avatar for my ENS name cryptopunk.eth — upload it to objekt.sh as image/png and store it permanently on Arweave so I can use the content hash to update my ENS record.”
Store agent report as permanent document
“My agent finished its research report as a PDF. Store it on Arweave under agent42.eth with type application/pdf so I have a permanent, decentralized permalink I can share.”
Pin profile JSON metadata for ENS domain
“Upload this JSON metadata file to objekt.sh under mydao.eth as type application/json — I want it pinned permanently on IPFS with the content hash returned so I can set it as my ENS contenthash.”
Technical details
Endpoint
PUThttps://api.objekt.sh/%7Bname%7D/%7Btype%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to permanently store a file on Arweave or IPFS and associate it with an ENS name — especially when the resulting content hash will be used to update an ENS contenthash record. It is the right choice for AI agents that produce files (images, documents, JSON metadata) and need decentralized, permanent, CDN-accessible storage with ENS identity linking. Prefer it over generic S3/cloud storage when permanence, decentralization, and ENS integration matter.
Side effects
- Invalid or unresolvable ENS name — 400 or 422 error

- Payment not received or insufficient USDC — x402 payment required error
- File too large for the selected storage tier
- Arweave or IPFS backend temporarily unavailable — 503 error
