FetchDelta is a paid HTTP API for AI agents that need fresh public web pages as clean markdown or structured diffs.

What pages should agents use FetchDelta for?

FetchDelta is best for public docs, release notes, changelogs, pricing pages, and policy pages that an agent needs to check before answering or acting.

How does payment work?

FetchDelta returns HTTP 402 payment requirements and accepts x402 payments over Base mainnet USDC for individual resolve or diff requests.
