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.

Pricing Page Audit

Send competitor pricing pages before you buy the monitor.

FetchDelta maps submitted public pricing, plan, terms, and packaging pages into a pending Starter Watchlist. Use this when the buyer knows the competitors but wants the watchlist checked before paying.

Audit Outcome

Usable public URLs become the first pending Starter Watchlist, capped at 25 pages for the $99 plan.
Pages that are private, duplicate, or too broad are separated before recurring monitoring starts.
Workflows with more than 25 pages can move into the $499 managed pilot or a broader team plan.
