# Seistream

> Seistream is the block explorer for Sei Network (mainnet `pacific-1`,
> EVM chain id `1329`). It indexes both the Cosmos SDK layer and Sei EVM:
> blocks, transactions, accounts, contracts, tokens, validators,
> governance and IBC. Data is available as a web UI and a public JSON API.

If you are an agent fetching on-chain data, **use the JSON API** at
`https://api.seistream.app/api/v2/*` instead of parsing HTML.
`robots.txt` disallows `/transactions/`, `/blocks` and `/codes` HTML
on purpose. Reads need no auth. Same payload as the UI. OpenAPI:
<https://api.seistream.app/swagger>.

For AI tools, connect MCP (streamable HTTP) at
`https://api.seistream.app/mcp`. Expanded catalog:

## APIs

- [v2 OpenAPI (Swagger)](https://api.seistream.app/swagger): machine-readable REST schema.
