What Coinranking does and who it's for
Coinranking exposes a REST API for pulling live and historical cryptocurrency data into applications. The core value proposition is breadth: a single integration gives you prices in both crypto and fiat denominations, coin metadata (descriptions, logos, social links), exchange listings, market (trading pair) data, blockchain details, and aggregate market statistics. With 43 endpoints and a 9.9 popularity score among API directories, it's one of the more widely adopted crypto data feeds available.
The target audience ranges from hobbyist developers building portfolio trackers to fintech teams that need a reliable, low-latency feed behind a production dashboard. The free Basic tier makes it approachable for prototyping, while the Pro and Ultra tiers are designed for apps that need high throughput or access to the more granular data sets.
Endpoint walkthrough
The API is organized into logical resource groups. Here's what each group provides and, importantly, which plan unlocks it.
Coins (partially free)
The coins endpoints are the heart of the API. GET /coins returns a ranked list of coins with prices, market caps, and supply data. GET /coin/{uuid} retrieves a single coin's full profile. Price history is available via GET /coin/{uuid}/history, making it straightforward to render time-series charts. GET /coins/trending returns the top 50 trending coins by user engagement.
Several more granular coin endpoints are Ultra-only: OHLCV data (GET /coin/{uuid}/ohlc), gains and losses over multiple intervals, fiat prices across all currencies, exchange and market listings for a specific coin, and historical market cap, rank, and supply series. If your use case needs candlestick charts or multi-fiat price tables, plan on the Ultra tier.
Stats (partially free)
GET /stats provides a global snapshot — total market cap, total trading volume, coin count — at no cost. The deeper historical series (global market cap history, global trading volume history, Bitcoin dominance history) are Ultra-only. These are the endpoints that power macro-trend charts and are worth factoring into your tier decision if your app has a market-overview screen.
Exchanges and markets (Ultra-only)
All exchange and market endpoints require the Ultra plan. This covers exchange lists ranked by 24-hour trading volume, individual exchange details, the coins and markets listed on each exchange, and new coin listings. Similarly, GET /markets and GET /market/{uuid} — which give trading pair data across exchanges — are gated behind Ultra.
Blockchains (Ultra-only)
GET /blockchains and GET /blockchain/{name} let you retrieve metadata about blockchains and look up a coin by its contract address. These endpoints are useful for wallet or explorer integrations but are unavailable below Ultra.
Supporting resources (free)
GET /reference-currencies returns the fiat and crypto denominations accepted as price reference units. GET /tags and GET /tag/{slug} expose coin categories with market statistics per tag. GET /coins/trending and GET /stats round out the free tier with enough data to build a meaningful MVP.
Pricing breakdown
| Plan | Price | Monthly requests | Rate limit | Overage |
|---|---|---|---|---|
| Basic | $0 | 5,000 | — | None |
| Pro | $30 | 1,000,000 | 100 / second | None |
| Ultra | $150 | 5,000,000 | 6,000 / minute | $0.0002 / request |
The Basic tier's 5,000 monthly requests equate to roughly 166 calls per day — enough for a personal project polling prices every few minutes, but it will run dry quickly in any multi-user application. Pro raises the ceiling to 1 million requests and adds a defined rate limit of 100 per second, which comfortably supports production apps with moderate traffic. Ultra's 5 million monthly requests come with a 6,000-per-minute cap and metered overage at $0.0002 per additional request, making cost somewhat predictable even under spiky load.
The most important cost driver on Ultra isn't volume — it's feature access. Exchange, market, blockchain, OHLCV, and bulk-coin endpoints are simply unavailable on lower tiers regardless of how many requests you have left.
Practical use cases
Portfolio tracker or price widget — Basic or Pro is sufficient. Use GET /coins, GET /coin/{uuid}, and GET /coin/{uuid}/history to display live prices and sparkline charts. Add GET /reference-currencies to let users switch denominations.
Exchange comparison tool — Requires Ultra. The GET /exchanges, GET /exchange/{uuid}/coins, and GET /exchange/{uuid}/markets endpoints give you the data to rank exchanges by volume and show which pairs trade where.
Market analytics dashboard — Requires Ultra for the historical global stats (market cap history, trading volume history, Bitcoin dominance). The free GET /stats endpoint provides the current snapshot, but trend charts need Ultra.
DeFi or token explorer — The blockchain lookup endpoint (GET /blockchain/{name} and contract-address resolution) combined with OHLCV and supply history makes Ultra the necessary tier for anything with on-chain context.
Limitations and things to check before integrating
Tier gating is significant. A notable share of the most interesting endpoints — exchanges, markets, OHLCV, blockchain data, bulk coin exports — sit exclusively behind the $150/month Ultra plan. If you're scoping a project and assume that Pro unlocks all endpoints, you'll hit a wall.
Free tier is genuinely limited. 5,000 requests per month sounds reasonable, but if you're polling prices for even 20 coins every five minutes, you'll exhaust the quota in under two days. The free tier is best treated as a development and evaluation environment rather than a production option.
No overage on Basic or Pro. Only Ultra has defined overage pricing. On Basic and Pro, requests simply stop being served once the monthly cap is reached — plan your polling intervals accordingly.
Success rate and latency are strong. The recorded 100% success rate and 156 ms average latency suggest a reliable infrastructure, which matters for front-end integrations where timeout errors would be user-visible.
Getting started
The full developer documentation is at developers.coinranking.com/api/documentation. The API uses standard REST conventions with JSON responses. A reasonable integration path is: start on Basic to validate your data model and endpoint choices, move to Pro once you're ready to go live with a user-facing product, and evaluate Ultra only when the gated endpoints become a concrete requirement. Given the metered overage on Ultra, instrumenting your request count before upgrading is worth a few hours of work.
