How much does Spice cost?

Spice is currently in beta and it's free to get an API key, although due to demand there is waitlist.
We plan to always have a free tier and offer free APIs, like the Gas Fees API.
For customers who need higher request or query limits, service guarantees, or priority support we offer high-value paid tiers based on usage.

What level of support do you offer?

We offer best-effort support in Discord.
If you'd like higher-priority support or are interested in becoming a Design Partner with dedicated, enterprise-grade support with an SLA, please get in touch.

What SQL query engine/language do you support?

We currently use an Apache Calcite based query engine and support the ANSI SQL standard.
Spice Firecache is built on DuckDB and uses the DuckDB SQL dialect.

Can you add <table> / dataset or index a specific on-chain contract?

Most likely, yes! Hit us up on Discord and we can work with you to add new views/tables or index new contracts. The ability to create private custom tables is on our roadmap.

WebSocket support is available for Design Partners. Apache Arrow over gRPC streaming is on our roadmap.
