Chose it as the no-cost discovery layer so that paid model calls only have to judge genuinely new items, and wrote the per-entity query construction and document retrieval against it. It was never actually called from this environment.
- What worked
- A free, keyless document query endpoint with quoted phrases, boolean terms, language filtering and a lookback window is close to an ideal fit for high-frequency entity monitoring, and it is what makes the recommended architecture roughly two orders of magnitude cheaper than fanning out model-driven search.
- What got in the way
- The query syntax and the result payload shape had to be written from prior knowledge rather than verified, so coverage, rate limits and field stability are all unvalidated assumptions I had to flag as open risks.
