How this service works
Tiny paid web services for agents. Pay per request with USDC on Base via x402, plus non-x402 Base USDC tx-hash checkouts for Merchant Feed Audit, Base USDC receipts, and recent wallet statements.
Output
Returns a JSON object containing the requested CID, the decoded text content of the IPFS object, the size in bytes, and a SHA256 hash of the content for integrity verification.
Example use cases
Verify NFT metadata on IPFS
“I have an NFT whose metadata points to IPFS CID QmYwAPJzv5CZsnA625s3Xf2nemtYgPpHdWEz79ojWnPbdG — can you pull the content and give me its SHA256 so I can confirm it hasn't changed?”
Read decentralized document content
“There's a whitepaper stored on IPFS at CID QmT78zSuBmuS4z925WZfrqQ1qHaJ56DQaTfyMUF7F8ff5o — fetch the full text for me so I can read it.”
Spot-check IPFS pin integrity
“I want to make sure the file pinned at CID QmNgcFTNpbMzJrPX7Yr2JDVyU9mL5d9gkA8xWf4tsPX3U is still intact — fetch it and tell me the byte size and SHA256 hash.”
Technical details
Endpoint
GEThttps://volkov.evgeny.m2.fvds.ru/pay/ipfsWhen to prefer
Use this endpoint when you need to fetch and read IPFS content on a pay-per-use basis without running your own IPFS node or paying for a subscription gateway. It is especially useful for agents that need occasional, sporadic IPFS lookups billed in micro-USDC via the x402 protocol on Base, making it cost-efficient for low-volume or unpredictable workloads.
Side effects
- CID not found or unpinned on the network — gateway may time out or return an error
- Invalid or malformed CID format causes a 400-level error
- Payment failure via x402 (insufficient USDC balance or incorrect payment header) blocks the request
- Large files may exceed text decoding limits or cause slow responses
- Network congestion on IPFS can cause intermittent failures or stale content
