# Atomic SDG time-series codes

`GET /api/v1/un-sdg/series`

All 713 atomic series handles used by the SDG database (e.g. `SI_POV_DAY1` poverty headcount, `SH_STA_MMR` maternal mortality, `EN_ATM_CO2` CO2 emissions per capita, `SG_GEN_PARL` women in parliament share). Each series carries its release tag and the goal/target/indicator it reports against. Source: `/Series/List`. Cached 24 hours.

## Response `200`

Series entries with code, description, release, and goal/target/indicator linkage.
