Bigmap Table

GET /tables/bigmaps?args

Lists bigmap allocations and the most recent state of each bigmap. Use this table only when you have a very good reason, e.g. to search through all bigmaps of all contracts efficiently. A better way might be to use the explorer API endpoints.

Example

curl "https://api.tzpro.io/tables/bigmaps?limit=1&order=desc"

import (
  "context"
  "blockwatch.cc/tzpro-go/tzpro"
)

// create a new query object
q := tzpro.DefaultClient.Contract.NewBigmapQuery()

// add filters and configure the query to list all active keys
q.WithLimit(1).WithOrder(tzstats.OrderDesc)

// execute the query
list, err := q.Run(context.Background())

// walk bigmaps
for _, row := range list.Rows {
    // access BigmapRow structs

}
