API & data access

Free · CC BY 4.0 (attribute Dirr with a link) · updated 2026-05-30

Dirr publishes its decoded dataset and change feed as open JSON. Build dashboards, alerts, internal tools, or AI agents on top of it. No key required today; please attribute and don't hammer it (it's cached hourly).

Endpoints

Tools dataset

GET /api/tools.json: all 36 tools, decoded pricing tiers, pricing model, free tier, self-host, MCP support, integrations, our editorial score, the "gotcha", confidence, last-verified date, and sources.

Pulse change feed

GET /api/pulse.json: the 6+ tracked changes (price moves, capability and lifecycle changes) with old → new values and dates. The thing no static listicle can give you: a time series of what changed.

Shape

Each response includes version, license, docs, a count, and the data array. Fields are stable; we version-bump on breaking changes. CORS is open (Access-Control-Allow-Origin: *).

Example

curl

# cheapest tools with a free tier
curl -s https://dirr.ai/api/tools.json \
  | jq '.tools[] | select(.free_tier|test("free";"i")) | .name'

MCP server coming soon

We're building an Dirr MCP server so AI assistants (Claude, ChatGPT, Cursor) can query the dataset and change feed directly. For example, "what's the cheapest no-code agent builder with MCP support?" or "what changed in AI voice agents this week?" answered live from verified data, with sources. It will wrap the same endpoints above.

Want early access or a specific field exposed? Tell us and we'll prioritize it.

Terms

Free for any use under CC BY 4.0: attribute "Dirr" with a link to dirr.ai. Data is provided as-is; verify pricing on the vendor's site before purchase (see methodology). Don't scrape the HTML pages — use these endpoints.
