TCG API for Card Shops

Common workflows

• Daily inventory revaluation — bulk-price 10k singles in one batch call.
• Buy-list generator — auto-publish what you'll pay per condition.
• Multi-marketplace listing sync — change once, push everywhere.
• Slow-mover alerts when a card sits unsold for > 30d.

Code example

POST /v1/cards/batch-prices
{
  "card_ids": [101, 202, 303, ...]
}
→ returns array of {card_id, market, low, mid, high}
