How this service works
Fetch a file from IPFS by CID via gateway
Output
Returns the raw content stored at the given IPFS CID — this could be JSON, text, binary data, images, or any other file type that was pinned to IPFS. The response body contains the file content directly.
Example use cases
Retrieve NFT metadata from IPFS
“I need to read the metadata JSON for this NFT — it's stored at IPFS CID QmNLei78zWmzUdbeRB3CiUfAizWUrbeeZh5K1rhAQKCh51. Can you fetch it?”
Access decentralized document archive
“Pull the content of the whitepaper stored at IPFS hash QmT5NvUtoM5nWFfrQdVrFtvGfKFmG7AHE8P34isapyhCxX so I can read it.”
Verify on-chain data reference
“There's an IPFS CID referenced in this smart contract — QmXoypizjW3WknFiJnKLwHCnL72vedxjQkDDP1mXWo6uco — can you retrieve what's actually stored there?”
Technical details
Endpoint
GEThttps://x402engine.app/api/ipfs/getWhen to prefer
Use this endpoint when an AI agent needs to retrieve content from IPFS without operating its own node or gateway — ideal for reading NFT metadata, decentralized app data, or any content-addressed file referenced by a CID on-chain. Prefer this over public IPFS gateways when you need reliable, pay-per-call access integrated into an agent payment flow using USDC or USDm.
Side effects
- Invalid or malformed CID returns an error
- Content not found or unpinned on IPFS network results in a timeout or 404
- Payment failure via HTTP 402 if USDC/USDm balance is insufficient
- Network timeout if IPFS peers holding the content are unreachable
- Large files may be slow or fail if retrieval takes too long
