Everything the table draws on continues here: how firm the #1 is, the per-criterion arithmetic behind each score, who pays ChainChoice, and the full guide to choosing.

Direct answer

What is the best market-data apis in 2026?

CoinMarketCap API ranks #1 overall for market-data apis on ChainChoice. Credit-metered REST API for price, volume and exchange data with published per-tier credit quotas. It holds that rank under an affiliate-blind methodology scored across 4 published, weighted criteria — the code that ranks providers physically cannot read affiliate payouts (CI-enforced), so a payout can't move a rank. The verdict re-computes on every fee change, incident, or regulatory action; full reasoning and the audit receipt are below.

Best market-data apis in 2026

If the data will be visible to your own users, read the licence before the price list, because that is where this category actually binds. Redistribution is the right most products need and the one least often included: at Coinpaprika the comparison table marks it unavailable on every published tier including the $799 plan, and available only on a custom enterprise agreement. CoinMarketCap points API buyers at its commercial terms with a link that serves a marketing page instead. If your use is internal, the decision flips to cost at your real call volume — and the expectation about who hides pricing is inverted here, with the institutional vendor publishing numbered floors while a mass-market one does not.

CoinMarketCap API

Credit-metered REST API for price, volume and exchange data with published per-tier credit quotas.

Data checked Sep 2026

Credit-metered REST API for price, volume and exchange data with published per-tier credit quotas. Strongest on published cost at production call volume (8/10): CoinMarketCap prints Growth at "$ 299 /mo" for "2M call credits/mo", so a million credits costs $299 from the page alone; the step from Startup's 450K credits straight to 2M is steep and the unit is credits rather than calls. Weakest on redistribution and licensing rights (4/10): CoinMarketCap's pricing FAQ grants commercial use from Basic up but caps it at "one product with up to 100k users" for end users' "personal, non-commercial purposes", with wider scope only under an unpriced Enterprise licence; the linked Commercial Terms of Use lead to a marketing page, not a licence. Published price: Fetched 2026-09-27 from the CoinMarketCap API pricing page (HTTP 200, verified against the raw served HTML); every subscription price is unchanged from 2026-08-06.

Main tradeoff

Two things the page will not tell you plainly. The annual plans are not discounts — every yearly figure is exactly twelve times the monthly one ($3,588 = 12 x $299), and the "Save up to 20%" banner is measured against struck-through prices nothing is sold at; only the "10_perc_off_yearly_cmc" checkout code produces a real reduction. And if you need intraday history, the plan cards' "All time historical data" does not mean what it says: at Growth ($299/mo) the 5m-12h history window is three months, and reaching 2010 at intraday resolution requires Enterprise.

Fetched 2026-09-27 from the CoinMarketCap API pricing page (HTTP 200, verified against the raw served HTML); every subscription price is unchanged from 2026-08-06. Six tiers: Basic free, "15,000" credits/mo, "50 requests per minute"; Builder "$ 29 /mo" or "$ 420 $ 348/year", "150K call credits/mo", "300 requests per minute"; Startup "$ 79 /mo" or "$ 1140 $ 948/year", "450K call credits/mo", "600 requests per minute"; Growth "$ 299 /mo" or "$ 4500 $ 3588/year", "2M call credits/mo", "750 requests per minute"; Professional "$ 699 /mo" or "$ 10500 $ 8388/year", "5M call credits/mo", "1200 requests per minute"; Enterprise "Inquire for pricing", "30,000,000" credits, "1600+ requests per minute". New since August: an "x402-Enabled Endpoints" table prices five endpoints at "0.01 USDC" per call with a "30/min per wallet" rate limit and the footnote "Pricing is subject to change. Please check the 402 Payment Required response for the latest pricing." NORMALISATION (2026-09-27, unit = USD/month for the cheapest published plan supplying >=1,000,000 credits/month, worked example): Startup's 450,000 credits fall short, so the cheapest qualifying plan is Growth at $299.00/mo; $299 / 2,000,000 credits = $0.0001495 per credit = $0.1495 per 1,000 credits — still the lowest per-call subscription rate in the pool. The x402 path at 1,000,000 calls would be 1,000,000 x $0.01 = $10,000.00/month, 33x Growth, so it prices sporadic agent traffic, not production volume. ANNUAL ARITHMETIC (worked example), checked on every priced tier: $348/12 = $29.00; $948/12 = $79.00; $3,588/12 = $299.00; $8,388/12 = $699.00 — every annual figure is exactly twelve times the monthly figure, so the yearly commitment carries no discount at any tier; the struck-through numbers ($420, $1,140, $4,500, $10,500) are reference prices nothing is sold at, and the page's "Save up to 20%" banner measures against them. The page still shows "Limited-time offer 🎉 10% off all yearly plans with code at checkout 10_perc_off_yearly_cmc", which would be a real reduction.

Recommendation summary

What should decide this category

Will the data be visible to your own users, and does the tier you are pricing actually permit that?

What does the bill look like at your real monthly call volume, not on the free tier?

How far back does intraday history go on the plan you are buying, as opposed to on the marketing card?

CoinGecko API

Credit-metered REST and WebSocket API covering listed assets plus on-chain DEX data.

Credit-metered REST and WebSocket API covering listed assets plus on-chain DEX data. Strongest on coverage and documented granularity (8/10): CoinGecko's docs print 1,500+ exchanges, 18,000+ coins, 1,800+ DEXes and 39M+ tokens, the broadest venue set in the pool, and its API FAQ states endpoints are cached to around 1 to 5 minutes with paid plans refreshing as fast as 30 seconds; no tick-level or order-book product is published. Weakest on redistribution and licensing rights (4/10): CoinGecko's API Terms let a buyer charge for products that integrate the API but forbid selling, sub-licensing or redistributing access except under an Executed Agreement, and require a "Powered by CoinGecko" credit, a cache refresh at least every 24 hours and deletion of the Data on termination. Published price: Fetched 2026-09-27 from the CoinGecko API pricing page.

Coinpaprika API

Per-call REST market data API with published per-tier call quotas across six named plans.

Per-call REST market data API with published per-tier call quotas across six named plans. Strongest on published cost at production call volume (9/10): Coinpaprika prints Pro at "$199.00/mo" against "1,000,000" calls a month, so the bill for a million calls is stated on the page with no derivation and lands well under $300 — the lowest published monthly outlay in the pool at that volume. Weakest on redistribution and licensing rights (3/10): Coinpaprika's API Terms of Use grant commercial use only on paid plans, require the credit "Powered by Coinparika" and bar further distribution of Data beyond the integration purpose; the pricing table marks redistribution allowed only under Enterprise, the one column priced "Custom". Published price: Fetched 2026-09-27 from the Coinpaprika API pricing table (HTTP 200), read from the raw served HTML rather than a rendered summary; every figure is unchanged from 2026-08-06.

Kaiko

Institutional tick-level trade and order-book data with reference rates the vendor states are BMR-compliant.

Institutional tick-level trade and order-book data with reference rates the vendor states are BMR-compliant. Strongest on coverage and documented granularity (9/10): Kaiko's product page sells tick-level trades and Level 2 order books as tiers, with "1-second to 1-day granularity" across "over 100 exchanges"; the deepest order-book history is shorter than the headline (best bids and asks since December 2022, market depth on a 1-month rolling window). Weakest on what the free tier actually survives (2/10): Kaiko publishes no free tier: the lowest floor is "From $1,000 per month" and the Pricing and Licenses page offers only "Request a Quote" and "Request a Trial", with no self-serve key, call allowance or trial terms. Published price: Fetched 2026-09-27 from the Kaiko Level 1 & Level 2 Data product page (HTTP 200) and confirmed in the raw served HTML; https://www.kaiko.com/products/market-data still redirects to this page.

Frequently asked

Questions people ask before choosing data apis

Can I show this data to my own users?

Only if your plan grants redistribution, and that is rarer than the pricing pages suggest. Coinpaprika's own comparison table, read from its raw served HTML, marks redistribution unavailable on Free, Starter, Pro, Business and Ultimate — every published tier, including the $799 one — and available only under a custom enterprise agreement. One of the mass-market vendors here does grant it, and its terms expressly permit charging for products that integrate the API, subject to an attribution requirement with a specified minimum font size. The general rule for this category is that the pricing page tells you the cost and the terms page tells you whether you may do the thing you are buying it for.

Which vendor is cheapest?

It depends entirely on your call volume, and the extremes are further apart than the marketing implies. The only vendor publishing an exact per-call price settles it on-chain in USDC with no account required — and normalised to a per-call basis it is the most expensive here by two to three orders of magnitude, which is a reasonable trade for zero onboarding on low volume and a poor one at scale. At the other end, the institutional vendor a buyer would assume routes everything through sales publishes numbered monthly floors on its product page. Price the plan at the volume you will actually run, not the tier you will start on.

How much history does the free or entry tier really give me?

Much less than the plan cards imply, and this is the most common surprise in the category. CoinMarketCap advertises all-time historical data while capping intraday history at one month on its startup tier and three months on the $299 growth tier, with full history only on enterprise. That distinction between daily closes and intraday granularity is what decides whether the plan supports a backtest or only a chart, so check the granularity row rather than the headline before committing to a tier.
