Chain API

The Chain API provides standard REST endpoints for querying blockchain state — blocks, transactions, accounts, balances, validators, and token metadata.

​
Base URL

http://67.205.164.156:1317
This is the Light Client Daemon (LCD) REST interface running on the primary validator node. All endpoints return JSON.

​
Authentication

All read endpoints are public. No API key or authentication is required for queries. Transactions must be signed client-side before broadcasting. See the SDK docs for signing helpers.

​
Rate Limits

Endpoint TypeLimit
Read queries100 requests/min per IP
Transaction broadcast10 requests/min per IP
For higher throughput, run your own node.

​
Common Patterns

​
Pagination

Most list endpoints support cursor-based pagination: 
# First page (10 results)
curl "http://67.205.164.156:1317/cosmos/bank/v1beta1/balances/xyz1...?pagination.limit=10"

# Next page (pass next_key from previous response)
curl "http://67.205.164.156:1317/cosmos/bank/v1beta1/balances/xyz1...?pagination.key=ABC123&pagination.limit=10"

# Include total count
curl "http://67.205.164.156:1317/cosmos/bank/v1beta1/balances/xyz1...?pagination.count_total=true"

​
Error Responses

Errors return a standard structure: 
{
  "code": 5,
  "message": "rpc error: code = NotFound desc = account xyz1... not found",
  "details": []
}
CodeMeaning
2Unknown error
3Invalid argument
5Not found
11Out of range
