GET /api/agile/<region>/rates/

Returns Agile-format half-hourly rates in chronological order — for pulling historical data into Excel or similar. With no parameters, returns today's slots (UK local day). Add start and end for a specific date range.

Parameters:

• start — start date in YYYY-MM-DD format (optional)
• end — end date in YYYY-MM-DD format (optional)
• local — set to 1 to return valid_from/valid_to as plain UK local time (no UTC/BST offset conversion needed on your end); omit for UTC (default)

Examples:

/api/agile/G/rates/ — today, UTC

/api/agile/G/rates/?local=1 — today, UK local time

/api/agile/G/rates/?start=2026-07-01&end=2026-07-15 — date range, UTC
