How this service works
Retrieves IPFS content by CID and optional path through public gateways, returning base64, text, or parsed JSON with a 5 MB hard cap. Use it as an IPFS fetch API, CID resolver, or NFT metadata fetcher.
Output
Returns the content of the specified IPFS CID (and optional sub-path) in one of three formats: base64-encoded binary, plain UTF-8 text, or a parsed JSON object. Content is capped at 5 MB. Includes any relevant content-type metadata from the gateway response.
Example use cases
NFT metadata resolution
“I have an NFT whose token URI points to IPFS CID QmPK1s3pNYLi9ERiq3BDxKa4XosgWwFRQUydHUtz4YgpqB — can you fetch that metadata and show me the name, description, and image fields?”
Decentralized config file retrieval
“My app stores its config file on IPFS at CID bafybeiemxf5abjwjbikoz4mc3a3dla6ual3jsgpdr4cjr3oz3evfyavhwq with path /config.json — please fetch it and return the parsed JSON.”
IPFS-hosted whitepaper fetch
“Fetch the text content stored at IPFS CID QmT78zSuBmuS4z925WZfrqQ1qHaJ56DQaTfyMUF7F8ff5o so I can read the whitepaper.”
Technical details
Endpoint
POSThttps://x402.agentutility.ai/ipfsWhen to prefer
Use this endpoint when you need to resolve IPFS CIDs to their content programmatically from within an agent workflow — especially for NFT metadata, decentralized config files, or any Web3 resource whose URI starts with ipfs://. Prefer this over direct IPFS gateway calls when you need a reliable, agent-friendly API with consistent response formatting (base64/text/JSON) and a known 5 MB cap. It is settled via x402/USDC so it integrates naturally into autonomous agent payment flows without requiring API keys.
Side effects
- CID not found or unpinned on available gateways — returns 404 or gateway error
- Content exceeds 5 MB hard cap — request rejected or truncated
- Invalid or malformed CID — returns parsing error
- Gateway timeout if content is slow to retrieve from the IPFS network
- Path not found within the CID's DAG — returns path resolution error
- Non-UTF-8 content requested as text — encoding error
