AgentWork Web Evidence
Check whether a public webpage changed since your previous read. Send prior text_sha256 for a compact changed/unchanged result, or previous_text for added and removed lines. If you omit a baseline, this is a first snapshot (stores nothing server-side; returns current text + hash). Useful for documentation, pricing-page and policy monitoring. $0.005 USDC on Base or $0.01 USDC on Algorand per successful check. HTML/text only; no JavaScript rendering.
