HTTP API

Query web3 data with SQL via the HTTP API

Blockchain and contract data may be queried by posting SQL to the /v1/sql API and /v1/firesql API for Firecached data. For documentation on the Spice Firecache see Firecache.

See Tables for a list of tables to query or browse the example queries listed in the menu.

Requirements and limitations

• An API key is required for all SQL queries.

• Results are limited to 500 rows. Use the Apache Arrow Flight API to fetch up to 1M rows in a single query or the Async HTTP API to fetch results with paging.

• Requests are limited to 90 seconds.
