A QUESTION WORTH ANSWERING

What changed in the market snapshots for our coin watchlist?

Monitor CoinGecko public coin-market observations for a configured watchlist. Compare saved price and market metadata with timestamps. Bounded snapshots, not a trading feed.

Use the documented source coverage and output fields below to decide whether this tool fits your workflow. A bounded run is a sample, not a guarantee of complete source coverage.

A CLEAR DATA CONTRACT

Inputs you can configure

FieldTypeMeaning
coinIdsarray

Up to ten values. Blank uses bitcoin.

keywordsarray

Optional case-insensitive OR filter on title and tagline within the returned source window; this is not a source-wide search.

maxResultsinteger

Global saved-row cap across this run. Does not promise complete source coverage.

comparePreviousboolean

First comparison run establishes a baseline. Reuse the same inputs and snapshot name. One writer per snapshot.

onlyChangesboolean

Enables comparison. An unchanged run can correctly return zero rows.

snapshotNamestring

1–80 letters, numbers, underscores or hyphens. Use a distinct name for independent workflows.

maxRunSecondsinteger

Requests share the remaining time budget. The platform timeout may stop work earlier.

KNOW THE COST

Event pricing

Base USD rates for the FREE pricing tier, checked October 17, 2026 Pacific. Plan discounts and future pricing changes may apply. Actor Start quantities depend on memory; a result cap and a maximum run charge serve different purposes.

EventUSD per eventWhat is charged
Actor Start$0.00005Charged when the Actor starts running. Number of events charged depends on Actor memory (one event per GB, minimum one event).
Saved observation$0.001One confirmed observation saved to the dataset.

SOURCE COVERAGE & PRACTICAL LIMITS

Full product guide

Documentation captured from build 1.0.2. Example outputs retain their original sample context; they are not live results.

CoinGecko Market Watchlist - Prices, Volume & Changes

Keep coin identity, source freshness and market values explicit, with comparisons that distinguish the source's 24-hour change from changes between your own observations.

Monitor exact CoinGecko coin IDs with USD prices, market caps, volumes, source timestamps and saved comparisons. Clear missing-data handling and CSV/JSON exports. Public API; no trading or wallet access.

Start in under a minute

  1. Paste coingecko coin ids into the first input field, or use the included sample.
  2. Keep the five-result limit for your first run and choose Start.
  3. Open Observations, Scope and diagnostics, or the Readable run report in Output. Export CSV or JSON from the dataset.
{
  "coinIds": [
    "bitcoin"
  ],
  "maxResults": 5
}

No source account, API key, paid proxy or extra subscription is required for these public endpoints. Source availability and rate limits still apply.

Who this helps

Researchers and dashboard builders maintaining small crypto market watchlists.

What you receive

One row per unique confirmed observation. Keyword filters inspect titles and taglines within the current feed window; they do not expand source coverage. Source timestamps that merely refresh do not create a change by themselves. Every row includes a stable recordId, title, source URL and observation time.

Field Meaning
coinId Source-reported coin id; missing optional values remain null.
symbol Source-reported symbol; missing optional values remain null.
currency Source-reported currency; missing optional values remain null.
price Source-reported price; missing optional values remain null.
marketCap Source-reported market cap; missing optional values remain null.
volume24h Source-reported volume24h; missing optional values remain null.
priceChangePercent24h Source-reported price change percent24h; missing optional values remain null.
lastUpdatedAt Source-reported last updated at; missing optional values remain null.
comparisonStatus not_requested, new, changed or unchanged
changedFields Fields different from your last saved observation

Saved comparisons

Enable Compare with saved observations, choose a snapshot name, and reuse the same input scope. The first run establishes history; it cannot report changes before that point. Enable Save only new or changed observations for later runs if you want a change-only export. An unchanged run can correctly save zero rows.

Only confirmed saved rows advance history. A bounded or failed run never establishes that a missing record was deleted. History is stored in a named key-value store in the running user's account. Use one writer per snapshot: do not overlap runs against the same snapshot. Change the snapshot name when starting a new independent workflow.

Scope and limitations

Current CoinGecko USD market snapshots for exact coin IDs, not ticker resolution. Source prices can be delayed or cached; lastUpdatedAt is retained. Public API rate limits apply. No historical candles, trading execution, investment advice or prediction.

At most ten input values and five hundred saved rows per run. Each input performs one bounded public source request. Each exact coin ID returns at most one observation. Responses are capped at 8 MiB and share the run deadline. No authentication bypass or code execution is performed. HTTP 429 stops further requests. Source failures appear in SUMMARY and the HTML report, never as paid data rows.

Pricing

The configured base price is $0.001 per saved observation, plus $0.00005 per start at the default memory. Five observations cost $0.00505 at that base rate. Applicable plan discounts and the Store pricing panel govern actual charges. Set a maximum charge in Run options. Diagnostics, reports and unchanged skipped rows are not dataset result events.

Make it recurring

Save an Actor task with your inputs, then attach an Apify Schedule. For change detection, keep the same snapshot and avoid overlapping runs. Add an integration to deliver results to your own spreadsheet or workflow. No external delivery is enabled automatically.

Examples

  1. CoinGecko coin IDs: bitcoin — A bounded bitcoin observation sample. Review source evidence and export rows or compare them in a later run.
  2. CoinGecko coin IDs: ethereum — A bounded ethereum observation sample. Review source evidence and export rows or compare them in a later run.
  3. CoinGecko coin IDs: solana — A bounded solana observation sample. Review source evidence and export rows or compare them in a later run.
