Find marketplace tools by describing what you need in plain words (e.g. 'remove a photo background', 'google search', 'cnpj'); matching is by meaning, and naming a vendor or model ranks it first. An empty query lists every live tool. Returns slugs, prices and quality stats, plus total and has_more. When has_more is true, call again with offset = next_offset. Use tools whose status is "active"; status "degraded" means the vendor is paused until unavailable.available_at, so pick another tool.
