A schema guarantees every run returns a predictable JSON payload.

Field types

• Text: freeform string, useful for names and addresses.
• Number: decimal-safe, accepts locale formatting and normalizes to floats.
• Currency: returns { amount, currency } pairs.
• Table: nested rows with typed columns.
• Enum: restricts to a list of values; handy for status codes.

Configure these in Studio → Processor → Schema or via the API.

curl -X PUT https://api.algorythmos.fr/processors/invoice-extractor/schema \
 -H "x-api-key: $ALG_KEY" \
 -H "Content-Type: application/json" \
 -d '{
  "fields": [
    {"name":"invoice_total","type":"currency"},
    {"name":"due_date","type":"date"},
    {"name":"line_items","type":"table","columns":[
      {"name":"description","type":"text"},
      {"name":"quantity","type":"number"},
      {"name":"unit_price","type":"currency"}
    ]}
  ]
}'

Validation hooks

• Enable strict typing to coerce numbers and dates.
• Use required flags to block incomplete extractions.
• Subscribe to schema drift alerts via Console → Settings → Alerts to catch unexpected fields.
