Spanish Day-Ahead Electricity Price API

A Spanish day-ahead electricity price API returns the OMIE wholesale day-ahead print as JSON. On Energy-API the symbol is OMIE_ES_DA. Call GET https://energy-api.com/api/v1/latest?symbols=OMIE_ES_DA with query api_key. Official latest sample dated 2026-06-11 prints 82.30 with currency EUR.

Starter is $19.99/mo (5,000 calls, 5 symbols, trial 7 days / 50 calls). Do not send base=USD if you need EUR symbols — they are dropped. Top-level base on the mixed sample is MIXED. There is no MCP (the MCP host does not resolve). Docs: energy-api.com/docs.

Use cases

Retail vs wholesale. Store OMIE_ES_DA next to a PVPC series (GET /api/v1/electricity/hourly documents PVPC_ES_2TD as a separate symbol).
Daily dashboard. Read dates.OMIE_ES_DA — energy markets publish on business days.
Multi-market card. Same latest call can include Brent / TTF / EUA if you omit base.
