## Verdicts

**Jina Reader.** One URL prefix, no key needed, Markdown back. No price per token in any currency on the public page.

**Spider.** Keyless /scrape and working x402 v2 on every core route, so an agent needs no account. Operated by BAGELMEN LLC with no address, retention periods or DPA in the privacy policy.

## Before you call either

### Jina Reader

1. Prefix the URL, `https://r.jina.ai/https://example.com`, and read the Markdown
2. Send `x-max-tokens` to cap a page, or `x-token-budget` to refuse one that's too big
3. Use `x-target-selector` when you need one part of a page
4. Keyless is 20 requests a minute and can't search. Add a key for loops or s.jina.ai
5. Send `x-no-cache: true` when a page may have changed or a blocked response got cached

### Spider

1. Every content route returns a JSON array, even /scrape. The status field is the page's, not the API call's
2. Leave request on smart and set return_format to markdown for LLM input
3. Set limit on /crawl. Unset, it caps only at your credit balance
4. Use /scrape with `stealth: true` instead of /unblocker, which is deprecated
5. Honour Retry-After on 429. Keyless use allows 4 requests a minute
