Overview
APIs.guru OpenAPI Directory Scraper
Scrape the APIs.guru OpenAPI Directory, the largest free collection of public API specs, up to a million APIs per run. Every API comes with its provider, category, version, and machine-readable spec URL. No API key. Export to CSV, JSON, Excel, or XML.
APIs.guru is the de facto registry of public OpenAPI specifications, but browsing it manually means clicking through thousands of entries. This Actor reads the directory directly, filters by provider, category, or search term, and returns each matching API as one flat row with its spec URL ready for downstream tooling.
| Who uses it | What they scrape APIs.guru for |
|---|---|
| Integration engineers | Discover which public APIs exist for a domain before building a connector |
| API product managers | Benchmark competitor API surface area and versioning patterns |
| LLM tool builders | Gather spec URLs to convert into agent tools or RAG datasets |
| Developer relations teams | Find APIs in a category to partner with or feature in a directory |
What it does
This Actor collects API metadata from the APIs.guru OpenAPI Directory and returns each API as a flat row with provider, category, version, and spec URL.
- 🔍 Provider filter: return only APIs whose provider domain contains a string like google or amazonaws.
- 🏷️ Category filter: narrow to APIs.guru categories such as cloud, analytics, or payment.
- 📝 Search term: substring match in API title or description to find exactly what you need.
- 🔗 Spec URLs included: every row carries the machine-readable OpenAPI spec URL for direct download.
Results export to CSV, JSON, Excel, or XML, or straight from the API.

Configure the run
Drive the Actor with a provider domain, a category, or a free-text search term, alone or together, and cap the result count with maxItems. The Input tab lists every parameter.
A first run with the defaults:
{
"maxItems": 10
}
A larger pull:
{
"maxItems": 200
}
Pricing
Pay-per-result: $0.021 per result collected. You pay only for the results written to your dataset.
| Results collected | Approximate cost |
|---|---|
| 100 results | $2.10 |
| 1,000 results | $21.00 |
| 10,000 results | $210.00 |
New Apify accounts start with $5 in free credit.
Free users
Free-plan runs return up to 10 results as a preview. Upgrade your Apify plan to collect up to 1,000,000 results per run.
Run it
- Create a free Apify account with $5 in credit.
- Open the APIs.guru OpenAPI Directory Scraper.
- Set your inputs and any filters, then click Start.
- Export the results as CSV, Excel, JSON, or XML from the Dataset tab.
Run it programmatically through the Apify API (run-sync-get-dataset-items) or the ApifyClient for JavaScript and Python.
Use with AI agents (MCP)
Give an AI agent live access to APIs.guru through the Model Context Protocol. Add the Actor to Claude, Cursor, or any MCP client:
claude mcp add --transport http apify "https://mcp.apify.com?tools=parseforge/apis-guru-openapi-directory-scraper"
Then prompt it in plain language to run the scraper and read back the results.
Troubleshooting
Why am I getting no results?
Check your filters. The provider and category filters are substring matches, so a typo or overly specific term can return nothing. Try broadening the search term or clearing filters.
Why did I only get 10 results?
Free users are limited to 10 APIs per run. Upgrade to a paid plan and set maxItems higher to scrape more.
The spec URL returns a 404.
APIs.guru occasionally has stale entries. The URL is provided as listed in the directory; if it is broken, check the API's own documentation.
Can I get the full OpenAPI spec instead of metadata?
This Actor returns directory metadata only. Use a spec scraper like OpenAPI Spec Scraper to fetch and normalize the full spec.
