<full markdown content with all required sections, internal links, infographics, and code blocks>

We must ensure the content includes TL;DR, sections as required, internal links naturally, enhanced code blocks with title and line highlighting, at least 2 infographic components (Stats Grid, Step Flow, TryIt Block). Must include at least 3 practical code examples (Python, cURL, batch/async). Must mention AlterLab naturally at most 4 times (not counting code examples). Must emphasize 'data API' framing.

We must include disclaimer near the top: 'This guide covers extracting publicly accessible data. Always review a site\'s robots.txt and Terms of Service before scraping.'

We need to keep length 1500-3000 words. We'll aim for ~1800 words.

We need to embed infographic components as HTML blocks.

We must not use em dashes; use commas or "to". Also no em dashes in subject lines (but this is content). Also no superlatives.

We must avoid banned phrases.

We need to be careful with line highlighting syntax: {5-12} inside code block after title.

We must include internal links: [AlterLab pricing](/pricing), [Extract API docs](/docs/api/extract), [Getting started guide](/docs/quickstart/installation).

We must not exceed 4 mentions of AlterLab outside code blocks. Let's count: we can mention maybe 3 times.

We need to ensure the FAQ answers are 1-2 sentences each.

Now craft the content.

First, TITLE line: exactly "TITLE: Ahrefs Data API: Extract Structured JSON in 2026"

EXCERPT: need 150-160 chars, include 'ahrefs data api'. Let's craft: "Learn how to extract structured Ahrefs data via API using AlterLab's data API for reliable JSON output in 2026." Count characters: Let's count: "Learn how to extract structured Ahrefs data via API using AlterLab's data API for reliable JSON output in 2026." That's about 104? Let's count precisely. We'll aim for ~155.

We'll do: "Extract structured Ahrefs data via API with AlterLab's data API: get reliable JSON output for metric_name, value, date and more in 2026." Count: Let's count characters including spaces. I'll approximate; we need 150-160. Let's craft longer: "Extract structured Ahrefs data via API using AlterLab's data API to obtain typed JSON output for metric_name, value, date, source and category—ideal for AI training, analytics and competitive intelligence in 2026." Let's count roughly: Might be ~180. Need 150-160. Let's try to hit 155.

We'll write: "Extract structured Ahrefs data via API with AlterLab's data API to get typed JSON output for metric_name, value, date, source and category—perfect for AI training, analytics and competitive intelligence in 2026."

Now count: Let's count characters manually.

"Extract structured Ahrefs data via API with AlterLab's data API to get typed JSON output for metric_name, value, date, source and category—perfect for AI training, analytics and competitive intelligence in 2026."

Count characters including spaces:

I'll copy and count roughly:

category—perfect (category—perfect: category (8) + em dash? we cannot use em dash. Must avoid em dash. Use hyphen? Actually we need to avoid em dash. Use " - " maybe? But we can use "—" is em dash, banned. So we must avoid em dash. Use " - " with spaces? We'll use " - ". So "category - perfect". Let's adjust.

We need to avoid em dash. So replace with " - ". So phrase: "category - perfect". That adds space hyphen space.

Let's rewrite sentence: "Extract structured Ahrefs data via API with AlterLab's data API to get typed JSON output for metric_name, value, date, source and category - perfect for AI training, analytics and competitive intelligence in 2026."

Now count again.

That's 210 characters, too long. Need 150-160.

We need shorter. Let's aim for ~155.

We can cut some words.

Try: "Extract structured Ahrefs data via API with AlterLab's data API to get typed JSON for metric_name, value, date, source and category - ideal for AI training and analytics in 2026."

Count.
