Queries

Contract events and transactions queries.

New queries can be added on request. If you cannot find the appropriate query for what you need, ask on our Discord server.

Authentication

All queries require an authentication header. You’ll need to provide a JWT token, which will be given to users that have access to Mercury (get access).

Example Authentication Header

Include the JWT in the request header as follows:

Authorization: Bearer YOUR_JWT_TOKEN

Pagination & Limits

Paginated endpoints accept the following pagination params:

• limit (default: 100, max: 1000) – requests exceeding the max are clamped to 1000

• offset (default: 0)

• cursor – the id (events) or tx hex (txs) of the last row from the previous page; when set, offset is ignored

Example Variables for Docs

Will be used in the docs for the upcoming examples
