Resource and maintenance requirements for Cardano blockchain components (e.g. cardano-node, cardano-db-sync) are ever-growing. Along with that, every builder needs to identify how to query complex information from the chain.

Frequently Asked Questions
The name Koios – derived from ancient Greek ‘Κοιος’ – meaning “question,” “inquiry,” or “inquisitiveness.” is the Titan of Resolve and Intelligence and also a god of heavenly oracles.
It will be increasing list of community builders. But for initial think-tank and efforts, the work done is primarily by guild-operators who are well recognised team of members behind tools like CNTools, gLiveView, topology Updater, etc. We also run a parallel a short (30-min) epoch blockchain, viz, guild used by many for experiments.
For most of the queries, there are no charges. But there are DDoS protection and strict timeout rules that may prevent heavy consumers from using this remotely (for which, there should be an interaction to ensure the usage is proportional to sizing and traffic expected).
All the Postgres codebase against dbsync instance is available on guild-operator’s github repo here. Feel free to raise an issue/PR to discuss anything related to those queries.
