This information began as a spreadsheet with 68 free crypto APIs in it. I pulled the names from our founder’s GitHub listing and added what it misses. Then I opened each pricing web page.
Greater than a dozen had been lifeless, stale, trial-only, or had no actual free tier. That’s the catch with a free crypto API. The worth is zero, so no one reads the boundaries till they break.
The 23 that survived are beneath, grouped by the job they do. CoinStats Crypto API is first, and I can be trustworthy about why. I may also be truthful to the remainder.
Our bias, up entrance
We make CoinStats API, so sure, we’re biased, and we all know it. So this information sticks to plain details: endpoints, limits, and public pricing. The decision is yours.
Key takeaways
- Each free crypto API has three limits: month-to-month quota, price cap, and license.
- Twelve of the 23 want no API key. Eleven want a free key, no card.
- CoinStats API leads for market, pockets, and DeFi knowledge on one free key.
- Six well-known crypto APIs misplaced their free tier or shut down since 2025.
- Match the API to the job, then take a look at the free tier on actual calls.
What makes free crypto API
A free cryptocurrency API is an information endpoint you may name with out paying. Each one among them stops at a broadcast restrict. The restrict is the product, and every part else on the pricing web page is ornament.
Free also can imply gone. CoinCap’s keyless v2 API vanished in 2025, and each tutorial that used it broke.
Three limits matter: the month-to-month quota, the speed cap, and the license. Quotas are available calls or credit. Fee caps are available requests a second or a minute.

A credit score is a weighted name. Heavy endpoints price extra credit than mild ones. Twenty thousand credit can imply 20,000 value lookups or 50 DeFi calls.
New to this? Begin with our primer on what a crypto API is. For simply costs, our crypto value API information walks via the primary name.
APIs are how software program talks now, and crypto isn’t any exception. Postman’s 2025 State of the API report places API-first adoption at 82% of organizations. For crypto apps, the free tier is the place that work begins.
Fee limits aren’t stinginess. NIST’s SP 800-228 (2025) ranks price limiting among the many best API instruments. A supplier with clear limits is a supplier that plans to remain up.
So what do you have to examine earlier than you decide one? Six issues.
- Free quota. What number of calls or credit a month, and do they renew?
- Signup friction. No key, a free key, or a card on file?
- Information depth. Costs solely, or wallets, DeFi, and danger too?
- Protection. The cash, chains, and venues you want.
- Docs and limits. Printed numbers you may mannequin, not “contact us”.
- AI readiness. An official MCP server, so brokers can name it.
One observe on AI readiness. MCP, the Mannequin Context Protocol, lets an AI agent name an API instantly. Eleven suppliers right here ship one, so it’s desk stakes, not a tiebreaker.
The shift is wider than crypto. Per Postman’s 2025 report, practically one in 4 builders design APIs for AI brokers. “APIs are not simply powering functions, they’re powering AI brokers,” says Abhinav Asthana, Postman’s co-founder and CEO.
How we scored the 23
We scored each free tier on six standards, weighted towards quota and knowledge depth. Each quantity comes from the supplier’s official pricing web page, rechecked in October 2026. Suppliers we couldn’t confirm had been lower, and they’re listed close to the tip.
Swipe the desk sideways to check →
| Criterion | Weight | What we checked |
|---|---|---|
| Free quota | 25% | Calls or credit a month, and whether or not they renew |
| Information depth | 25% | Costs solely, or wallets, DeFi, danger, and historical past |
| Protection | 15% | Cash, chains, venues, and protocols |
| AI readiness | 15% | An official MCP server or agent tooling |
| Docs and limits | 10% | Printed numbers, not sales-only |
| Signup friction | 10% | No key, free key, or card required |
Two trustworthy notes. CoinStats API is our product, so it goes first, limits included. And 23 is a menu, not a podium.
The most effective decide is the one whose restrict you by no means hit.

How to decide on a free crypto API
Decide a free crypto API by the restrict you’ll hit first. A 100,000-call quota behind a 5-a-minute cap is a 7,200-call day. Learn the speed cap earlier than the quota.
Then match the info to the job. Costs solely? A keyless value API is sufficient.
Wallets, DeFi, and costs collectively? Decide the one which returns them in a single schema.
Breadth issues greater than most builders count on. A price-only API seems like sufficient till a person asks for pockets balances. Rely the info varieties you have to in six months, not right this moment.
Test the license too. A free crypto value API for private use can not ship in a paid app. CoinStats API permits industrial use on its free tier, and CoinPaprika doesn’t.
Then take a look at earlier than you commit. Run the free tier in opposition to your actual endpoints. Test the response form, the latency, and what a 429 seems like.
A homepage emblem doesn’t show a sequence is supported. The precise response does.
Your first request in a single minute
Most free crypto APIs return your first JSON in below a minute. Listed here are three calls, one with a key and two with out.
# CoinStats API: Bitcoin value and market knowledge (free key, 1 credit score)
curl -H “X-API-KEY: YOUR_KEY” “https://api.coinstats.app/v1/cash/bitcoin”
Get the important thing at openapi.coinstats.app. Hold it server-side, by no means in consumer code. This name prices 1 credit score; a pockets steadiness prices 40.
# CoinPaprika: Bitcoin ticker, no key
curl “https://api.coinpaprika.com/v1/tickers/btc-bitcoin”
# mempool.house: really helpful Bitcoin charges, no key
curl “https://mempool.house/api/v1/charges/really helpful”
Three habits save quota. Cache something that adjustments slower than you ballot, and again off on a 429. Log credit per endpoint from day one.
APIs we don’t suggest
Six well-known crypto APIs misplaced or by no means had a free tier by September 2026. Three extra are trial-only or stale. We checked every one, so that you would not have to.
CoinCap v2shut down 2025
CoinCap’s keyless v2 API shut down in 2025, and api.coincap.io not resolves. The v3 successor wants a key and permits 500 credit a month. Any tutorial nonetheless calling v2 is damaged.

Coinglass and Glassnodeno free API tier
Each are strong merchandise with no free API tier. Coinglass begins at $29 a month. Glassnode’s most cost-effective API entry is a restricted Mild API at $49 a month, yearly.
GoldRush (Covalent)trial solely
GoldRush presents 25,000 credit for 14 days, then $10 a month. It’s a good multichain API with no recurring free tier.
Unmarshalwebsite offline
Unmarshal’s website returned a 404 in October 2026, and its docs didn’t load. We couldn’t verify the API is maintained, so it’s out.
“CoinCap retired its free, keyless v2 API (the host not resolves) and v3 now requires an account and key,” says Mateusz Sroka, Lead Developer Advocate at CoinPaprika, in his migration information. In case your code nonetheless calls v2, it’s already damaged.
Dune was candid about why Sim went. “Sim served an actual want, however it pulled focus from the place we consider Dune wins: being the learn layer for onchain knowledge,” says Mats Olsen, co-founder and CTO at Dune, within the sundown announcement.
Another warning that applies to this listing too. CoinStats API, Chainbase, and Blockscout PRO invoice in credit, not calls. Learn the per-endpoint price earlier than you assume 20,000 means 20,000.
Conclusion: match the free tier to the restrict you’ll hit first
The most effective free crypto API is the one whose restrict you by no means attain. For many apps that’s CoinStats API, with 4 knowledge varieties on one key. For a value ticker with no signup, it’s CoinPaprika or CoinLore.
For onchain knowledge, begin with The Graph or Routescan. For DeFi, DefiLlama. For Bitcoin, mempool.house.
SlashData counts simply over 47 million builders worldwide in 2025. For many, a free tier is the primary crypto knowledge they are going to contact. Decide the one that also works subsequent 12 months.
