## Which one, for what

### Bright Data (C)

Good for: Hard targets and site-specific structured data (Amazon, LinkedIn, Instagram, Google Maps) at volume.

Ahead on:
- Agent ergonomics, 82 against 63
- Security & auth, 57 against 21
- Maintenance & community, 84 against 57

Watch for: No public status page or incident history

### Diffbot (C)

Good for: Agents that want typed article, product or discussion data from arbitrary pages without writing selectors, and teams that also want the Knowledge Graph.

Ahead on:
- Reliability, 55 against 35
- Schema & documentation, 83 against 74
- Transparency & trust, 68 against 59

Watch for: The token is sent as the `token` query parameter on Extract and Knowledge Graph calls. It is the only scheme in the OpenAPI file

## Verdicts

**Bright Data.** Pay only for successful requests, $1.50 per 1,000 on Web Unlocker and SERP. No public status page or incident history.

**Diffbot.** Extract returns typed JSON for articles, products, discussions and other page types with no selectors to write, under a public OpenAPI 3.1 contract and a free plan that needs no card. The API token travels in the URL query string, tokens carry no scopes, and no security page, certification or security.txt was found.

## Before you call either

### Bright Data

1. Connect with OAuth or keep the `?token=` URL out of logs and shared configs
2. Add `groups=` or `tools=` to the MCP URL only for the extractors you need. The full set is 69 tools
3. Retry `reject_block` errors, since each attempt uses a different peer. Certificate and DNS errors fail the same way twice
4. Back off on a 429 `sr_rate_limit`. Bright Data throttles a target whose success rate drops
5. Use the batch tools for up to 10 searches or scrapes in one call

### Diffbot

1. Call `GET https://api.diffbot.com/v3/analyze?url=<encoded URL>&token=<token>` when the page type is unknown. Use `/v3/article` or `/v3/product` to force one schema
2. Keep the token out of logs and shared URLs. It sits in the query string, so any proxy or log that records the request URL records the token
3. Stay under 5 calls a minute on Free, 5 a second on Startup and 25 a second on Plus. On 429 wait at least one second and back off
4. Check a 200 response for `errorCode`. The official client raises `ExtractionError` when a 200 reports a failed extraction
5. Set `useProxy=default` only when a site blocks the fetch. A proxied page costs 2 credits against 1
6. Install `diffbot` from PyPI, not `diffbot-python`, which stopped at 0.3.0
