  "notes": "Coverage note: the 'Web scraping & browser APIs' category has no tools in this release. That category's verification pass could not be completed for this build, and unverified tools were not listed rather than guessed. Firecrawl, Apify, and Browserbase are the planned first entries when verification is completed. Status changes caught during verification: Relay.app shut down permanently in 2026 and is listed as discontinued; Smithery ended its hosted connection services on 2026-10-31 and is now a free, non-proxied registry powered by Arcade.dev; standalone Clearbit pricing no longer exists post-HubSpot acquisition. ElevenLabs figures are from ElevenLabs' published pricing as carried by multiple secondary sources because elevenlabs.io blocked automated reading during verification. Make's entry price renders dynamically and could not be verified from its pricing-page text; Clay's own pricing page shows two different Launch prices ($167 headline vs $185 in its FAQ) \u2014 both are recorded in Clay's entry.",
