rankparse

Official Python SDK for the RankParse SEO API.

RankParse gives you cheap, programmatic access to 25+ SEO signals — backlinks, domain authority, tech stack, page metadata, and more — powered by pre-processed Common Crawl data.

Install

pip install rankparse

Requires Python 3.9+ and installs httpx automatically.

Quick start

Sync:

from rankparse import RankParseClient

client = RankParseClient(api_key="rp_...")

result = client.domain_authority("github.com")
print(result["data"])
# {"domain": "github.com", "score": 94, "backlinks": 12400000, ...}

Async:

import asyncio
from rankparse import AsyncRankParseClient

async def main():
    client = AsyncRankParseClient(api_key="rp_...")
    result = await client.domain_authority("github.com")
    print(result["data"])

asyncio.run(main())

Context managers (recommended for connection cleanup):

with RankParseClient(api_key="rp_...") as client:
    da = client.domain_authority("example.com")
    bl = client.backlinks("example.com", limit=50)

async with AsyncRankParseClient(api_key="rp_...") as client:
    da = await client.domain_authority("example.com")

Error handling

from rankparse import RankParseClient
from rankparse.errors import (
    AuthError,
    InsufficientCreditsError,
    NotFoundError,
    RateLimitError,
    APIError,
    RankParseError,
)

client = RankParseClient(api_key="rp_...")

try:
    result = client.backlinks("example.com")
except AuthError:
    print("Invalid API key")
except InsufficientCreditsError:
    print("Out of credits — buy more at rankparse.com/dashboard")
except RateLimitError:
    print("Rate limited — slow down")
except NotFoundError:
    print("Resource not found")
except APIError as e:
    print(f"API error {e.status}: {e}")
except RankParseError as e:
    print(f"Unexpected error: {e}")

All exceptions expose .status (HTTP status code) and .code (API error code string).

Response envelope

Every response is a dict with this shape:

{
  "data": [...],
  "credits_used": 2,
  "credits_remaining": 998,
  "domain": "example.com",
  "total": 1234,
  "limit": 100,
  "offset": 0
}

Fields domain, url, total, limit, and offset are only present when relevant.
