## Which one, for what

### Majestic API (F)

Good for: An agent that needs backlink, referring domain, anchor text and Trust Flow data in volume for an owner who already pays for the API plan.

Watch for: Clause 14.1(f) of the supply terms forbids querying Majestic's database or servers with automated tools without prior permission. This matters before any probe is run

### Moz API (E)

Good for: Agents that need Domain Authority, backlink lists, link intersects, keyword volume and difficulty, search intent and ranking keywords at a low entry price, on a read-only data set.

Ahead on:
- Reliability, 42 against 17
- Schema & documentation, 50 against 44
- Agent ergonomics, 74 against 54
- Security & auth, 38 against 32
- Payments & pricing, 20 against 15
- Maintenance & community, 28 against 22
- Transparency & trust, 59 against 53

Watch for: No working public status page was found, and moz.statuspage.io reports the Moz Status page as inactive

## Verdicts

**Majestic API.** Each command's cost in units is published and a sandbox endpoint returns sample data without spending allowance. API access starts at $399.99 a month with no trial, and no OpenAPI file, status page, numeric rate limit, SLA or API changelog was found. The supply terms require permission before querying with automated tools.

**Moz API.** The JSON-RPC API documents every error code, its rate limits and the row cost of each method, and failed validation uses no quota. No working status page, SLA, machine-readable spec or official SDK was found. Tokens carry no scopes, and the free plan needs a credit card.

## Before you call either

### Majestic API

1. Send requests by HTTPS POST with `app_api_key` in the body. The docs show GET URLs for demonstration only and plain HTTP still works
2. Always set `datasource=fresh` or `datasource=historic`. Without it the Historic Index is used when the plan includes it
3. Call `GetSubscriptionInfo` (no cost) before a large pull. `GetBackLinkData` spends 5,000 analysis units a call plus one retrieval unit a row
4. Read columns by header name, not position. The docs say column order can change between requests and Majestic may vary rows and columns at any time
5. Develop against `https://developer.majestic.com/api/json`, which costs no units, then switch the host to `api.majestic.com`
6. Ask the owner to confirm Majestic's permission for automated querying first. Clause 14.1(f) of the terms requires it

### Moz API

1. Send a request `id` of at least 24 characters (letters, numbers and hyphens). A UUID works. Shorter ids are rejected with -32654.
2. Stop on a 401. Ten 401 or 403 responses in five minutes block the caller for 30 minutes.
3. On 429 with code -32658 wait the `Retry-After` seconds. On code -32650 no wait time is given, so back off exponentially.
4. Call `quota.lookup` (free) before large pulls. List methods charge one row per result, and `limit` is capped at 50 on link lists.
5. Poll `async.call.lookup` for `data.keyword.serp.generate`, and collect the result within 20 seconds of first seeing it complete.
