Writing meta titles and descriptions for hundreds of pages is the kind of work nobody enjoys. You have to read the page, summarize it in 60 characters, write a 155-character description, hit search intent, include the right keywords, and not sound like a robot. For one page it's fine. For a 200-page site? You'll cut corners and your SEO will pay for it.

So I built Origrid Meta Gen — an API that does it for you. One call per URL, optimized output, ready to paste.

How it works

Send a URL, get meta tags back:

curl -X POST https://api.origrid.io/v1/meta/generate \
  -H "Content-Type: application/json" \
  -d '{"url": "https://yourblog.com/post-about-rust"}'

Response:

{
  "title": "Why Rust's Borrow Checker Saved Our Production Database",
  "title_length": 56,
  "description": "How a small team rewrote a memory-leaking Node service in Rust, eliminated 3 OOM crashes per week, and learned to love the borrow checker.",
  "description_length": 142,
  "url": "https://yourblog.com/post-about-rust"
}

The API:

1. Fetches the URL server-side
2. Extracts the main content (no scripts, no nav, no footer noise)
3. Sends it to Claude Haiku with a tuned prompt
4. Returns title (max 60 chars) + description (max 160 chars)
5. Validates lengths before returning

Why not just use ChatGPT?

You absolutely can. But:

1. Length validation is a pain — ChatGPT regularly produces 70-character titles that get truncated in Google. The API enforces limits on the server side and retries if it goes over.
2. You have to fetch the page yourself — adds boilerplate (HTML parsing, content extraction, dealing with bot blocks).
3. Prompt engineering takes iteration — I spent days tuning the prompt to avoid clickbait, generic phrasing ("Discover the secrets of..."), and meta descriptions that just repeat the title.
4. Cost at scale — GPT-4 for 1000 pages is expensive. Haiku is 30x cheaper and just as good for this task.

The API wraps all of that into one HTTP call.

Real examples

I tested it on a mix of content types. These are unedited outputs:

All under length limits. None start with "Discover" or "Learn how to". All capture the actual page intent.

Bulk processing for site migrations

The most useful case is when you migrate a CMS or relaunch a site with no meta tags. Here's a Python script that processes a sitemap:

import requests
import xml.etree.ElementTree as ET
import time

API_URL = "https://origrid-meta-gen.p.rapidapi.com/v1/meta/generate"
HEADERS = {
    "X-RapidAPI-Key": "your_key",
    "Content-Type": "application/json"
}

def get_meta(url):
    resp = requests.post(API_URL, headers=HEADERS, json={"url": url})
    return resp.json()

# Parse sitemap.xml
sitemap = requests.get("https://yoursite.com/sitemap.xml").text
root = ET.fromstring(sitemap)
ns = {"sm": "http://www.sitemaps.org/schemas/sitemap/0.9"}
urls = [el.text for el in root.findall(".//sm:loc", ns)]

# Generate meta for each
results = []
for url in urls:
    try:
        meta = get_meta(url)
        results.append({"url": url, **meta})
        print(f"OK: {meta['title']}")
    except Exception as e:
        print(f"FAIL: {url} - {e}")
    time.sleep(0.5)  # be nice to your rate limit

# Now you have a CSV ready to bulk-update your CMS
import csv
with open("meta_tags.csv", "w") as f:
    w = csv.DictWriter(f, fieldnames=["url", "title", "description"])
    w.writeheader()
    for r in results:
        w.writerow({"url": r["url"], "title": r["title"], "description": r["description"]})

200 pages = 200 API calls + 100 seconds of waiting + a CSV ready to import. Beats the 8 hours of manual work.

When it won't work

The API can't help if:

• The page is behind auth (it can't log in for you)
• The page is JavaScript-rendered with no SSR (it sees an empty shell)
• The page is mostly images with no text content

For SSR'd pages with real text, it works on the first try about 95% of the time in my testing.
