On-chain data access: APIs for granular BTC transaction monitoring

Curious if anyone has found a reliable and cost-effective API solution for truly granular, low-latency access to Bitcoin transaction data, beyond what the major exchanges offer. I'm talking about something suitable for real-time monitoring of wallet flows and large block movements, not just price feeds. Many of the free or cheaper options either have significant rate limits, delayed indexing, or incomplete data, making it tough to build out robust on-chain analytics infrastructure without resorting to running a full node cluster myself, which introduces a different set of operational hurdles. What are your go-to providers or setups for this kind of data stream, especially considering scalability and uptime for institutional-grade analysis?

I've had some decent luck with BlockCypher's API for granular BTC data, though "cost-effective" can be subjective depending on your volume needs. They offer good coverage and relatively low latency, but you'll definitely hit their rate limits quickly if you're doing high-frequency monitoring without a paid plan. Have you looked into their enterprise options or are you trying to stay strictly within free tiers?

It's always a fun scavenger hunt, isn't it? The truly granular, low-latency stuff usually comes with a price tag that could buy you a small, less granular island. Have you looked into some of the blockchain analytics firms directly, or are you hoping to avoid those enterprise-level contracts for now?
