Pin a query to Parallel

Over HTTP, send "requested_provider": "parallel" with the query.
In an agent connected over MCP, ask it to search with Parallel.

Results come back in the same shape for every provider, as the docs describe. Leave the field out, and Grounder routes each query to the provider most likely to answer it well.

Filters Parallel applies

Set them under filters. A filter a provider can’t apply returns 400 unsupported_filter.

Filter	Keeps
`domains`	Only these sites, or with `"mode": "exclude"`, none of them.
`recency`	The last so many days, or a `range` of dates.
