How it works
Three steps. No accounts.
Tack uses the x402 protocol — HTTP-native payments that settle on-chain. Your wallet address is your identity and your access key.
01

Pin or upload content

Send a CID to pin, or upload a file directly. The API returns an HTTP 402 with the exact USDC price for your request.

02

Pay with USDC

Your agent or client signs a USDC payment via x402. No ETH for gas, no approval transactions — just a single signature.

03

Content is pinned

Your content is pinned to IPFS and retrievable via the gateway. The response includes an auth token for managing your pins without re-paying.

Integrate
One endpoint. Give it to your agent.

Tell your AI agent to use this URL for IPFS storage. It handles the rest — pricing, payment, pinning. Standard HTTP + x402. Use @x402/fetch to handle payments automatically, or implement the protocol manually.

If you want the details

Use @x402/fetch to wrap your fetch — it reads the 402 response, signs the USDC payment, and retries automatically. Or handle x402 manually if you prefer.
