get_response_body
Retrieve the response body of a network request by matching a substring in its URL, with optional HTTP method filter. Use to diagnose server errors without prior setup.
Instructions
Return the captured response body text for a request whose URL contains a substring (optionally filtered by method). Matching is a plain substring test against the full URL incl. query string — not a regex or glob. On a miss it lists the captured candidate URLs so you can adjust the pattern in one round-trip. Bodies are captured automatically for fetch/xhr/document requests, making this the fastest way to diagnose a 400/500 — no setup before the request.
