## Research notes
Added 2026-08-25 in the coverage sweep. Scored official because the plugin repo sits in the fiber-ai GitHub org and the docs are served from the vendor's own api.fiber.ai host. Runs on a credits model, and notably the vendor's own agent-facing docs instruct the agent to confirm spend before any chargeable call and to run a preflight cost estimate before audience enrichment, which is the most agent-aware cost-safety design found in this directory. Y Combinator company. NOT VERIFIED: public pricing is not posted, so per-credit cost is unknown and api_gate "paid" reflects the absence of any free tier rather than a confirmed price.
