Capabilities

Tools 34

addCard

Write. Add one prompt/answer pair. Optional cardNote. Eligible immediately. listDue still applies newCardsPerDay. The response is prompts only.

Discovered
addCards

Write. Add 1 to 100 prompt/answer pairs to one owned deck. All or nothing. Prompts only. After this, re-run previewDeadlinePlan with that deckId.

Discovered
applyDeadlinePlan

Write, destructive. Same plan as previewDeadlinePlan, then PATCH that owned deck to the recommended integer. deckId is required. Discuss the number first.

Discovered
archiveDeck

Write, destructive. Soft-archive a deck; it leaves listDue and the default deck list until unarchiveDeck. Cards and schedules stay. A second call returns alreadyArchived true.

Discovered
bootstrapAccount

Write. Same mint as createAccount. No bearer.

Discovered
createAccount

Write. No bearer. Mint an anonymous account and a personal API token. Save the token for later Authorization: Bearer calls. The token is the tenant. Do not send a userId.

Discovered
createDeck

Write. name and newCardsPerDay are required. Choose that integer with the person; there is no default of 20. Optional description and deckNote. Setting a note does not move dueAt.

Discovered
