## Which one, for what

### DataForSEO (B)

Good for: Agents and products that need raw SEO data in bulk at a low unit price, across SERPs, keyword volumes, backlinks, ranked keywords and traffic estimates, and that can work with a task queue.

Ahead on:
- Reliability, 84 against 51
- Schema & documentation, 86 against 58
- Agent ergonomics, 84 against 58
- Security & auth, 45 against 21

Also in its favour:
- Runs on your own machine

Watch for: The REST API takes one account-wide login and password over HTTP Basic, with no scopes or read-only credential

### SE Ranking API + MCP (D)

Good for: An agent that needs keyword, backlink, domain and AI search visibility data at a published price per call, or that manages rank tracking projects for an SE Ranking customer.

Also in its favour:
- No incidents deducted, where DataForSEO loses 6 points for them

Watch for: No scoped or read-only keys. The MCP docs say a key has the same access as the account, including Project API deletes

## Verdicts

**DataForSEO.** Per-request prices are public for every endpoint, a $1 credit and a free sandbox need no payment, and the status feed shows no incident since 15 June 2026. The REST API accepts one account-wide login and password with no scopes, and no SLA or security certification was found in the reviewed pages.

**SE Ranking API + MCP.** Every Data API endpoint has a published credit cost, credits sell from $50 for 250,000 with no expiry, and a 14-day trial needs no card. Keys carry full account access with no scopes or read-only mode, the key may travel in the URL, and no security page, SLA or llms.txt was found.

## Before you call either

### DataForSEO

1. Check `status_code` on the response and on every task. HTTP 200 is returned for most errors, and 20000 or 20100 means success
2. Append `.ai` to Live and Task GET paths to get the trimmed response. The MCP `api_request` tool does this unless `noAiMode` is true
3. Build against https://sandbox.dataforseo.com/v3/ first. It is free and returns dummy data in the production structure
4. Use the standard queue (`task_post`, then `task_get` or a `postback_url`) for bulk work. Live Google Ads endpoints allow 12 requests a minute
5. Ask the account owner to set daily cost limits and an IP whitelist, since the credentials carry the whole prepaid balance

### SE Ranking API + MCP

1. Send the key as `Authorization: Token <key>`, not `Bearer` and not `?apikey=`, so it stays out of URLs and logs
2. Call `GET /v1/account/subscription` (0 credits) and read `units_left` before a large pull. A short balance returns `Insufficient funds`
3. Set `limit` and `cols` on per-record endpoints. Backlink summaries cost 100 credits a target and keyword rows 10 credits each
4. Stay under 10 requests a second on the Data API and 5 on the Project API per key. Repeated overruns block the Project API for 10 minutes
5. Ask the owner before any Project API or `PROJECT_*` create, update or delete call. The key has no read-only mode and nothing confirms a delete
