Rollytics exposes a read-only, KV Indexer endpoint-compatible (drop-in for most consumers) HTTP API for indexed chain data. This section documents the endpoints commonly used by wallets, explorers, and backend services. Base URL: https://<your-rollytics-api-host> OpenAPI: /swagger/doc.json Response schemas and full field definitions are in the OpenAPI spec. Examples below show representative payloads.

Conventions

Response format

All responses are application/json.

Pagination

Many list endpoints accept Cosmos-style pagination parameters. Pagination Parameters:

Name	In	Type	Default	Description
`pagination.key`	query	string	-	Cursor-based pagination, preferred for large datasets
`pagination.offset`	query	integer	-	Offset-based pagination
`pagination.limit`	query	integer	`100`	Pagination limit
`pagination.count_total`	query	boolean	`true`	Count total (when supported)
`pagination.reverse`	query	boolean	`true`	Reverse order. Default is descending; set `pagination.reverse=false` for ascending order

Pagination responses may include pagination.next_key, pagination.previous_key, and pagination.total, depending on the endpoint and data set. For exact response fields, refer to OpenAPI.

Pagination Examples

Key-based pagination:

# First page
curl "https://<host>/indexer/tx/v1/txs?pagination.limit=50"

# Next page using next_key from response
curl "https://<host>/indexer/tx/v1/txs?pagination.limit=50&pagination.key=<next_key_from_response>"

Filtering

Some transaction endpoints support filtering by message type via the msgs parameter:

Name	In	Type	Default	Description
`msgs`	query	array[string]	-	Message types to filter (comma-separated or multiple params). Example: `"cosmos.bank.v1beta1.MsgSend,initia.move.v1.MsgExecute"`

curl "https://<host>/indexer/tx/v1/txs?msgs=cosmos.bank.v1beta1.MsgSend&msgs=initia.move.v1.MsgExecute"
