q — keyword search across id, name, descriptioncategory — filter by category (ai, media, search, blockchain, data, etc.)status — active (has llms_txt docs, recommended) or limited (use with caution)limit — max results (default 20, max 100)offset — pagination offsetResponse:

curl -s "https://apiserver.mpprouter.dev/v1/services/catalog"
Returns all services. Use search instead for targeted queries.
When a service has docs.llms_txt, fetch it to learn the request body format:
curl -s "<llms_txt_url>"
curl -X POST "https://apiserver.mpprouter.dev/v1/services/{service}/{operation}" \
-H "Content-Type: application/json" \
-d '{"your": "request body"}'
