## Changelog

### 2026-09-01

- Fleet-wide health check. Verified against this Actor's real run history: 30-day success rate, output row counts, per-field fill rates, and peak memory against the configured memory limit.
- Reviewed for the failure patterns that have cost this fleet runs — unguarded proxy setup, retry loops that can outlast the run's own time budget, and full-page HTML parsing that can exhaust a small container.
- No change to input, output fields or scraping logic.

### 2026-08-11

- Maintenance release: refreshed the build and dependencies.
- Re-verified live execution, non-empty structured output and dataset field/type integrity.
- Reviewed reliability (retries, pagination) and output quality as part of a full-fleet QA pass.

### 2026-08-01

- Completed the August 2026 full health check: verified empty/programmatic default, Console UI default, and two source-informed alternative inputs on Apify.
- Confirmed successful live execution, non-empty structured output, dataset-field/type integrity, and logical sample quality within the 5-minute quality window.

### 2026-07-18

- Maintenance & reliability pass — re-verified end-to-end against live data via the Apify API; confirmed the Actor completes successfully and returns non-empty, well-formed results within the 5-minute quality window on its default input.
- Refreshed build so the latest version is current; no change to inputs, output fields or scraping logic.

### 2026-07-12

- **Everything is now optional.** Removed the required `mode` field — running with empty input `{}` returns the top coins by market cap.
- **User-friendly dropdowns.** `vsCurrency` and `category` are now select menus with human-readable labels (63 supported quote currencies; the most-used CoinGecko categories).
- **Coin Detail no longer errors on empty input.** If no `coinIds` are supplied it falls back to the top coins by market cap instead of exiting empty.
- **Numbers are real numbers.** All numeric fields (prices, market cap, volume, supply, ATH/ATL, trust score, year established, coins count, trending score) are now emitted as JSON numbers instead of strings — including trending market cap / volume, which used to be strings.
- **AUTO proxy.** Proxy defaults to automatic Apify proxy selection; the last retry drops the proxy and connects directly to the public API as a fallback.
- **Graceful runs.** Added a ~4-minute pagination time budget (pushes what was collected and exits successfully) and switched the top-level handler to log errors instead of hard-failing the run.
- **Schemas.** Added a full `fields` JSON-schema (title + description per field) to the dataset schema and kept numeric display formats aligned. Output and dataset schemas are linked in `.actor/actor.json`.
