Stopped at key: blocked. Next: let an agent get a key on its own

Brave Search API is a web/news/image/video/place search service for developers. Without any account, an agent could run real searches in the browser-based docs playground, but getting its own API key requires an activated plan, and every plan, even the free one, needs a credit card. The agent stopped at that card form.

Got in; first wall at delete (blocked). Does it all on its own, payment included

Parallel is an API/tool suite for web search, research, and data-monitoring that AI agents can call. An agent got free search and extraction through a no-account tool, and could pay small per-call fees to search, extract, summarize, and run research tasks without ever creating an account. Signing up for a full account worked without any human checks, but every paid feature on that new account needed a saved credit card, which the test could not provide.
