One key made the difference
Adding Crypto Market Data took ten minutes because the credential already existed. The vendor onboarding we skipped would have taken longer than the integration.
Rachel Kimani
Head of Integrations
Solved Trading bots for us
We brought Crypto Market Data in for Trading bots and it has not needed revisiting since. The response shape matched the documentation on the first call, which is rarer than it should be.
Chidi Nwosu

Fast enough to sit in the request path
47ms median is quick enough that we call Crypto Market Data synchronously rather than queueing it. That removed a whole background worker from our architecture.
James O'Connor
Technical Director
Free tier covered the whole prototype
I built the entire risk monitoring flow against Crypto Market Data before anyone had to approve a purchase order. By the time we paid, we already knew it worked.
Aisha Suleiman
Digital Lead
Replaced a fragile in-house on-chain job
We had a script doing research dashboards that broke every few months and only one person understood. Crypto Market Data replaced it in an afternoon and nobody maintains it now.
Anna Kowalski
Senior Developer
Errors are actually readable
When something goes wrong Crypto Market Data says what and why, with a code I can branch on. I have integrated exchanges services that return 200 with an error buried in the body, so this is a relief.
Yusuf Abdullahi
Head of Engineering
Held up under real load
We push Crypto Market Data hard during peak and latency has stayed flat. No throttling surprises, no silent degradation — the numbers on the listing matched what we measured.

Good coverage for order book
We checked Crypto Market Data against our own order book reference data before committing. Coverage was better than the incumbent we were paying four times as much for.
