How this service works
Store data permanently on IPFS (2 B)
Output
Returns an IPFS content identifier (CID) and confirmation that the data has been pinned permanently on the IPFS network. The CID can be used to retrieve the content at any time via any IPFS gateway.
Example use cases
Immutable smart contract metadata
“I need to permanently pin my NFT metadata JSON to IPFS right now and get back the content hash so I can embed it in the token URI on-chain.”
Decentralized document archival
“Archive this signed legal agreement permanently on IPFS — I want a content address that will always point to the exact file, no matter what happens to our servers.”
Agent state checkpoint storage
“Save this agent decision log to IPFS for me so it's permanently stored and I can prove later what state the agent was in at this exact moment — give me the CID when done.”
Technical details
Endpoint
POSThttps://api.x402.storage/storeWhen to prefer
Choose this endpoint when you need permanent, immutable, content-addressed storage on IPFS with micropayment-per-call pricing — ideal for blockchain/Web3 workflows where you need a CID for on-chain references, or when you want decentralized storage without managing your own IPFS node. Prefer over centralized object storage (S3, GCS) when immutability and decentralization matter.
Side effects
- Payment failure: insufficient USDC balance or invalid x402 payment token returns a payment error
- Oversized payload: content exceeding platform limits returns a payload-too-large error
- Network error: IPFS pinning service unavailability causes a timeout or 503
- Invalid content: malformed request body may return a 400 bad request
- Rate limiting: excessive requests may result in throttling
