Authentication

FactorsToday uses a query parameter API key. OMNI uses the x-api-key header: 
# FactorsToday
curl "https://api.factorstoday.com/api/factors/catalog?apiKey=YOUR_KEY"

# OMNI Datastream
curl -H "x-api-key: $OMNI_DATASTREAM_API_KEY" \
  "https://api.secapi.ai/v1/factors/catalog"

​
Example: factor catalog

curl -H "x-api-key: $OMNI_DATASTREAM_API_KEY" \
  "https://api.secapi.ai/v1/factors/catalog"

# Filter by category
curl -H "x-api-key: $OMNI_DATASTREAM_API_KEY" \
