Why it ranks first

Why CoinMarketCap API leads this category right now

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's pricing page prints the Growth plan at "$ 299 /mo" with "2M call credits/mo". The Startup plan below it, at "$ 79 /mo", carries 450K credits and falls short of 1,000,000 calls a month, so the step up to Growth is steep. Weakest on redistribution and licensing rights (4/10): CoinMarketCap's pricing page says the commercial licence "covers one product with up to 100k users" and that "you may not redistribute or resell it as a standalone service". The link it gives for its Commercial Terms of Use leads to the API marketing page, not to a terms document. Published price: Fetched 2026-11-10 from the CoinMarketCap API pricing page (HTTP 200, verified against the raw served HTML); every subscription price is unchanged from 2026-08-06.

Best for

Published cost at production call volume — 8/10

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 10 November 2026 from the CoinMarketCap API pricing page (HTTP 200, verified against the raw served HTML); every subscription price is unchanged from 6 August 2026. 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 (10 November 2026, 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?

Considered and not ranked

1 product we looked at and left out

A shortlist is only honest if it says who it turned away. It was assessed against the same published criteria as the ranked table and excluded for a stated reason — not overlooked.

We assessed 8 products here and rank 7 — 88% of what we looked at. That share is of the products we assessed, not of the category: how many exist is not something we can count, so we do not claim a number for it.

What this ranking does not assess

Liveness failure: the operator stops, censors you or loses data.
Exit failure: you cannot get out at par, on time, or with what is yours.
Information failure: the number is wrong or bought, or your data leaks.

These can still cost you money here; the ranking does not measure them, so a high place says nothing about them. Which criterion scores each family, and why the others do not apply, is in /data/risk-coverage.json.

Direct answer

What is the best market-data API 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; the full reasoning and the audit receipt are under Methodology.

How you can lose money here, and what the ranking scores

None of this ranking's criteria scores a way of losing money; the families that apply are listed below as not assessed.

Not assessed by this ranking: Liveness failure, Exit failure, Information failure. A high place says nothing about these; the Methodology tab says what each means.

FAQs

3 questions readers ask before choosing market-data APIs.

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.

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.
