''Note: this is a draft page documenting the development of the GENI Collector API access.''

= GENI Collector API =

This page details the developmental progress and description of the GENI Collector API access system.

The API is accessed in similar fashion to accessing metric data from a GENI Monitoring DataStore. (ie: /API/data/?q={json})
