# What are the best financial data APIs for fintech developers consolidating market data feeds into integrated applications?

<p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">I've been researching <a class="a a--md" elv="true" href="https://www.g2.com/categories/financial-data-apis">financial data APIs</a> for fintech developers consolidating market data feeds into integrated applications for a roundup I'm putting together, and wanted to get practitioner input before I finalize it. Merge Unified, Plaid, and Finch keep coming up most, but curious what others think.</p><ul>

<a class="a a--md" elv="true" href="https://www.g2.com/products/apideck-unify/reviews"><strong>Apideck Unify</strong></a><strong>:</strong> Access to all integration platforms through one API, without building or maintaining separate connections for each.</li>
</ul><p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">Which of these have you actually used to consolidate multiple data feeds, and where did things hold up or break down?</p>

I’d ask teams where complexity showed up after launch: inconsistent data fields, delayed syncs, webhook reliability, coverage gaps, or compliance reviews. The strongest API is the one that lets developers ship faster without creating a hidden maintenance layer behind the scenes.
