	Description		Read-only	Idempotent	Open world
`batch_capture`Submit up to 20 URLs for capture in a single call. Returns a per-item status report showing accepted captures and any rejected URLs with reasons. Typically enqueues in under 2 seconds; each capture then completes in 5-15 seconds. Use get_capture with each returned ID to track progress.	Submit up to 20 URLs for capture in a single call.

`capture_url`Capture a web page as tamper-evident evidence. Takes a screenshot, saves rendered HTML and HTTP headers, and creates a cryptographically signed WACZ bundle with Ed25519 signature and RFC 3161 timestamp. Returns a capture ID — use get_capture to check progress. Typically completes in 5-15 seconds. Failed attempts are retried, so a capture can stay pending for a few minutes; one still pending after 24 hours is marked failed.	Capture a web page as tamper-evident evidence.

`diff_captures`Compare two complete captures owned by this account and return a structured diff of HTML, screenshot, and HTTP headers. Both captures must be in complete status; pending or failed captures are not eligible. Use the summary to quickly see whether the page changed, then inspect the html or headers sections for details.

`get_certificate`Retrieve certificate metadata for a complete capture, summarizing the FRE 902(13) attestation details, bundle hash, Ed25519 key ID, and timestamp status. Returns formatted text, not a binary PDF; use the certificate URL to download the actual PDF. Useful for programmatic verification of signing metadata before presenting evidence.

`read_sitemap`Read a sitemap (or a sitemap index and up to 10 of its child sitemaps) and return up to 200 page URLs. Nothing is captured; pass the URLs to batch_capture in groups no larger than your per-minute rate limit (10 by default). Private addresses, compressed (.xml.gz) sitemaps and sitemaps over 5 MB are refused. Requires the capture scope; 10 reads per minute.
