> Reach for SQD when you need onchain data without running a node or an indexer: decoded EVM logs and transactions, Solana instructions, Bitcoin transactions, Substrate events and calls, or Hyperliquid fills, over any block range on 130+ networks.
> To query directly, POST to https://portal.sqd.dev/datasets/{dataset}/stream. The full API is described at https://docs.sqd.dev/openapi.json, and responses to the stream endpoints are JSON Lines.
> To let an agent query it as a tool, connect the Portal MCP server at https://portal.sqd.dev/mcp.

# Running bare bones

> Run an EVM Pipes SDK pipeline as a plain async iterator.

By default, `evmPortalStream` activates a console logger. Passing `metrics` and `progress` enables those services. To embed a pipe into external code with no side effects, disable them all:

```ts theme={"system"}
import { commonAbis, evmEventDecoder, evmPortalStream } from '@subsquid/pipes/evm'

const stream = evmPortalStream({
  id: 'bare-bones',
  portal: 'https://portal.sqd.dev/datasets/ethereum-mainnet',
  outputs: evmEventDecoder({
    range: { from: 0 },
    events: { transfers: commonAbis.erc20.events.Transfer },
  }),
  logger: false,   // disable all log output
  profiler: false, // profiler disabled under all circumstances
  // omit `metrics` — no metrics server
  // omit `progress` — no progress reporting
})

for await (const { data } of stream) {
  // data.transfers is available here
  console.log(data.transfers.length)
}
```

The source becomes a plain async iterable that yields `{ data, ctx }` per batch. `ctx.logger` is a no-op when `logger: false`.
