CoinMarketCap Full Market Coin Export

Export the complete currently published CoinMarketCap listing universe with source prices in USD, BTC and ETH, supplies, rankings, volume/change metrics, tags, platform metadata and audit claims. The default is a whole-market current observation, not a top 100 sample or historical candle service.

Input and coverage

Default: quoteCurrencies=[USD, BTC,ETH], maxCoins=10000, pageSize="10000", maxPages=20 and maxRequests=30. The source observation on 2026-10-09 exposes 8,136 coins in one supported native 10000-row response; that count changes. The full-response default avoids inter-page rank movement. Select 100 or 500 rows for smaller windows; moving page totals, duplicates or gaps fail explicitly. Choose one to three USD/BTC/ETH/EUR quotes. All requested quotes are included in the coin fee. The native source is ordered by market_cap descending; this is source ordering, not an investment recommendation. Explicit coin/page/request caps can return a clearly marked partial prefix. Unexplained missing/repeated pages, changing totals/cardinality and source failures fail before output. A full result is the observed native current listing universe, not every inactive/archived token ever recorded or an atomic market snapshot.

Output

One coin_market row identifies the source coin ID, name, symbol, slug and public URL, source timestamps, all requested quote objects and published optional business metrics. Original source names and numerical values are retained, including fullyDilluttedMarketCap. That derived field appears identical across different quotes in the observed source; its units and any published tvl units are unconfirmed. Do not assume or recalculate units. Missing/null optional facts, including unavailable ATH/ATL and 7d/30d volume fields, are omitted and listed in availability. Actual published zero remains zero. Supply, audit flags and reports are source claims, not independently verified facts or safety scores. No returns, forecast, financial advice, exchange order books, wallet holders or historical-price backfill is promised.

Pricing and paid validity

Price: $0.00004 per unique delivered coin, including all selected quotes. No start, page or quote add-on. No valid coin rows = no coin charge. The observed 8,136-coin market is $0.32544 in Actor fees; default cap $0.40 and absolute 20,000-coin cap $0.80. A paid row requires exact nonempty identity/public URL, source update timestamp and actual numeric price+timestamp for every requested quote. Metadata-only, duplicate, malformed, excluded and failed-source records are not paid.

All source acquisition and row validation finish before paid delivery. The bounded response is parsed with ijson: validate its entire envelope and item count, then project one coin at a time without a full raw JSON tree. Stage at most 24 MiB, preflight the entire event allowance, then use SDK charged push_data in batches of at most 50 rows. The SDK charges coin-exported once for each item in each batch, not once per batch; verify returned charged_count and actual dataset/event parity. Insufficient allowance fails before any output/fees. Delivery errors propagate and cannot be reported as success.

Limits

Only HTTPS api.coinmarketcap.com/data-api/v3/cryptocurrency/listing and its robots.txt are acquired, with the matching jpmarketdata User-Agent, source robots rules, manual exact-host redirects and no login/key/cookie/proxy input. Forbidden/v1,/v2,account/community/private paths are unsupported. No website/third-party report/token-profile links are followed. Commercial extraction restrictions were actually read and recorded in the scout under DR-0007; public API availability is not a resale licence or endorsement.

256MB/300s Actor target. Serial requests have at least 1s between starts and 30s HTTP timeout; acquisition 180s and paid delivery 90s are bounded. Streaming limits: 4 MiB wire and 24 MiB decoded per listing response, 256 KiB robots, 64 MiB cumulative wire and decoded, 24 MiB staged output, 50 source attempts/40 pages/20,000 coins. No automatic retries. Body/transfer/output/deadline breaches fail explicitly; source 429/auth/timeout/parser errors fail before paid output. Cloud measured memory/cost and full-market billing parity are release gates, not proven by local prototypes.

Privacy

Only public project/business metadata is extracted. Coin names and text fields redact incidental email/phone strings; report URLs reject credentials/contacts. No personal profiles, account data, contacts, user wallets/holdings or cookies are extracted. Platform token contract identifiers are published project metadata. Raw source/tracking payload is not logged or persisted in fixtures.

Agent use

“Export the full current crypto market with USD, BTC andETH quotes so my research pipeline can compare liquidity and supply.” Empty input completes the currently observed listing universe. Use coverage, availability and source timestamps to assess the observations. The Actor is independent of CoinMarketCap.
