1 What it shows
A paid research chain can separate sourced observations from a model's unverified interpretation.
- Use Brave search and Serper scrape to collect bounded public evidence
- Optionally pay DeepSeek for a short draft while keeping its claim labeled unverified
- Check delivered bodies, settled merchants, buyer fees, and remaining budget after every purchase
- Publish a redacted Markdown and JSON comparison while private receipts stay in ignored out/
2 How it works
The runner checks each Catalog slug and payable path, buys rival search and company-page extraction, then optionally asks a model to draft two sentences from short excerpts. It records source URLs and asks a human to test whether the comparison is a real differentiator.
The Firefox versus Brave follow-up completed all three calls on September 15. A later read-only ledger check reconciled the initially Submitted Brave buyer fee to Settled; total merchant-plus-fee charge was $0.069.
| Paid service | Purpose | Observed charge |
|---|---|---|
| Brave | rival search | $0.035 |
| Serper | company-page scrape | $0.020 + $0.010 buyer fee |
| DeepSeek | optional draft | $0.004 |

The later Live follow-up delivered its first result in 13.48 seconds. The earlier representative run consumed 8¢ of its 25¢ cap, and its redacted sample is linked here. The model draft is unverified; check the cited pages before using the comparison. Running the Live script spends real money.
