v1.1.0 (2026-05)

Real-time analysis endpoints

Five new endpoints that fetch live data rather than querying the crawl index:

/v1/page-seo — title, meta description, H1, canonical, OG tags, and robots directives for any URL
/v1/tech-stack — server, framework, and CMS detection from live HTTP headers
/v1/site-health — HTTPS, redirect chain, robots.txt, and basic crawlability signals
/v1/sitemap — sitemap discovery and full URL list parsing
/v1/crawl-history — historical crawl frequency and first-seen date

New link analysis endpoints

/v1/competitor-gap — domains that link to a competitor but not to you, ranked by authority
/v1/link-audit — health score, risk flags, anchor profile, and top/risky backlinks in one call

Authority scoring

/v1/backlinks and /v1/referring-domains now accept ?score=true to include a normalised authority score (0–100) for each linking domain. Costs 1 extra credit per call.

Official SDKs

Python SDK — pip install rankparse
Node.js SDK — npm install rankparse

Both SDKs cover all live endpoints with typed responses and built-in retry logic.

Zapier and Make.com integrations

All 14 endpoints are now available as actions in Zapier and Make.com — no code required. Find them by searching "RankParse" in each platform's integration directory.

Free SEO tools

Eight tools available with no API key, rate-limited by IP:

Pre-built prompt templates for common SEO workflows — backlink audit, link gap analysis, competitor research, and more. Each workflow ships with setup instructions, a ready-to-paste agent prompt, and a REST fallback. Browse at /workflows.

Tiered credit packs

Credits now come in volume tiers — the more you buy, the lower the per-credit cost. Guest checkout is supported (no account required to purchase). Unused credits never expire.

Transactional emails

RankParse now sends emails at every meaningful account event:

Welcome — sent after account creation with your starting credit balance and a first API call example
Purchase confirmation — sent after every credit top-up with amount charged and new balance
Payment failed — sent if a card charge is declined, with a link to retry
Low credits warning — sent when your balance drops below a threshold
Credits exhausted — sent when an API call is rejected due to zero credits
API key created / revoked — sent when a key is added or deleted

All emails come from hello@rankparse.com. Reply to any email to reach the team.

Performance

Repeat lookups for domain authority, tech stack, and page performance now return in under 50ms
Improved query reliability — transient errors are automatically retried with per-request timeout budgets
