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

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

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"}'

Firecrawl

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

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:

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);

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
