Quickstart

Three paths to the same catalog — pick the one matching how you work.

1 — Browse as a human (30 seconds)

Open reqistry.dev/categories → pick a category.
Open any API → inspect trust score, health, pricing, CORS, OpenAPI, and warnings.
Compare two: /compare/open-meteo-vs-openweather
Search: reqistry.dev/search?q=weather

2 — Build from code

bash

# list categories
curl https://api.reqistry.dev/v1/categories

# search filtered
curl "https://api.reqistry.dev/search?q=email%20validation&pricing=free&cors=yes"

# profile + trust
curl https://api.reqistry.dev/v1/apis/open-meteo
curl https://api.reqistry.dev/v1/trust-scores/open-meteo

# compare side-by-side (2-4 slugs or ids)
curl "https://api.reqistry.dev/v1/apis/compare?ids=open-meteo,openweather"

# change feed
curl https://api.reqistry.dev/v1/change-feed?limit=20

All REST endpoints are JSON. Reads are public; bookmarks/stacks need auth.

3 — Let your agent do it (MCP)

bash

claude mcp add --transport http reqistry https://mcp.reqistry.dev/mcp
# then ask: "Find reliable free weather APIs that don't require OAuth."
# or: "Compare OpenWeatherMap alternatives for a browser app."

Full tool list → MCP tools catalog · Install for every client → install guide.

4 — Mobile

Install the Android app to save APIs into project stacks and receive health alerts on the go. Same catalog, same trust scores.
