# 9Router — Web Fetch

Requires `NINEROUTER_URL` (and `NINEROUTER_KEY` if auth enabled). See https://raw.githubusercontent.com/decolua/9router/refs/heads/master/skills/9router/SKILL.md for setup.

## Discover

```bash
curl $NINEROUTER_URL/v1/models/web | jq '.data[] | select(.kind=="webFetch") | .id'
# Per-provider params
curl "$NINEROUTER_URL/v1/models/info?id=firecrawl/fetch"
```

IDs end in `/fetch` (e.g. `firecrawl/fetch`, `jina/fetch`). `fetch-combo` chains providers with auto-fallback.

## Endpoint

`POST $NINEROUTER_URL/v1/web/fetch`

| Field | Required | Notes |
|---|---|---|
| `model` (or `provider`) | yes | from `/v1/models/web` (e.g. `firecrawl` or `jina-reader`) |
| `url` | yes | URL to extract |
| `format` | no | `markdown` (default) / `text` / `html` |
| `max_characters` | no | truncate output |

## Examples

### Jina Reader
```bash
curl -X POST $NINEROUTER_URL/v1/web/fetch \
  -H "Authorization: Bearer $NINEROUTER_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"jina-reader","url":"https://9router.com","format":"markdown"}'
```

### Exa
```bash
curl -X POST $NINEROUTER_URL/v1/web/fetch \
  -H "Authorization: Bearer $NINEROUTER_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"exa","url":"https://example.com","format":"markdown","max_characters":0}'
```

### Firecrawl
```bash
curl -X POST $NINEROUTER_URL/v1/web/fetch \
  -H "Authorization: Bearer $NINEROUTER_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"firecrawl","url":"https://example.com","format":"markdown","max_characters":0}'
```

### Tavily
```bash
curl -X POST $NINEROUTER_URL/v1/web/fetch \
  -H "Authorization: Bearer $NINEROUTER_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"tavily","url":"https://example.com","format":"markdown","max_characters":0}'
```


JS:

```js
const r = await fetch(`${process.env.NINEROUTER_URL}/v1/web/fetch`, {
  method: "POST",
  headers: { "Authorization": `Bearer ${process.env.NINEROUTER_KEY}`, "Content-Type": "application/json" },
  body: JSON.stringify({ model: "fetch-combo", url: "https://example.com", format: "markdown", max_characters: 5000 }),
});
const { data } = await r.json();
console.log(data.title, data.content.length);
```

## Response shape

## Provider quirks

| Provider | Auth | Best for |
|---|---|---|
| `firecrawl` | Bearer | JS-rendered pages, `format=markdown/html` |
| `jina-reader` | Bearer (optional) | Free tier (~1M chars/mo); fastest plain markdown |
| `tavily` | Bearer | Bulk extract; returns `raw_content` |
| `exa` | `x-api-key` | Pre-indexed pages; fast text extraction |
