Full detail for one book: synopsis, authors, series position, genres, and its page on siftivo.com. Accepts a work id, an edition id, or a slug.
Input Schema
{
"type": "object",
"properties": {
"id": {
"type": "string",
"minLength": 1,
"description": "A Siftivo work id, edition id, or URL slug"
}
},
"required": [
"id"
],
"additionalProperties": false,
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢what_to_read_next(workId)
Given one book, what to read after it: the next books in its series, more by the same author, and books that read like it. This is the same set the book page on siftivo.com shows.
Input Schema

"workId": {
"type": "string",
"minLength": 1,
"description": "A workId from search_books, get_book, or a URL slug"

An author, their biography, and the works Siftivo holds for them. Accepts an author id or slug.
Input Schema
{
"type": "object",
"properties": {
"id": {
"type": "string",
"minLength": 1

},
"required": [
"id"

}🟢get_reading_index(week)
The weekly Siftivo Reading Index: the fiction and nonfiction books moving most in cultural circulation this week, ranked.

{
"type": "object",
"properties": {
"week": {
"type": "string",
"pattern": "^\\d{4}-\\d{2}-\\d{2}$",
"description": "Edition week, YYYY-MM-DD. Omit for the current edition."
}
},
"additionalProperties": false,
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢recommend_from_description(description, limit, isFiction)
Describe what someone is in the mood for, in their own words, and get books that match. It suits a theme, subject or feeling ("books about grief", "cozy mysteries set in Cornwall"), and matches on meaning rather than on a title or an author name.
Input Schema
{
"type": "object",
"properties": {
"description": {
"type": "string",
"minLength": 1,
"maxLength": 300,
"description": "What the reader is after, in plain language"
},

"type": "integer",
"minimum": 1,
"maximum": 10,
"default": 5
},
"isFiction": {
"type": "boolean"
}
},
"required": [
"description"
],
"additionalProperties": false,
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢recommend_from_titles(titles, limit, isFiction)
Give Siftivo a few books someone liked, by title, and get books like them. Titles are resolved against the catalog first; anything that does not resolve is reported back rather than guessed at.
Input Schema
{
"type": "object",
"properties": {
"titles": {
"type": "array",
"items": {
"type": "string",
"minLength": 1
},
"minItems": 1,
"maxItems": 10,
"description": "Book titles, optionally \"Title by Author\""
},
"limit": {
"type": "integer",
"minimum": 1,
"maximum": 10,
"default": 5
},
"isFiction": {
"type": "boolean"
}
},
"required": [
"titles"
],
"additionalProperties": false,
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢get_my_library(status)
The signed-in reader's own Siftivo library: what they want to read, are reading, finished, or set down, with their ratings.
Input Schema
{
"type": "object",
"properties": {
"status": {
"type": "string",
"enum": [
"NOT_STARTED",
"READING",
"FINISHED",
"DNF"
],
"description": "Filter to one shelf. Omit for the whole library."
}
},
"additionalProperties": false,
"$schema": "http://json-schema.org/draft-07/schema#"
}🔴add_to_library(workId, readingStatus, rating, progress, notes)
Put a book on one of the signed-in reader's shelves, move it to a different shelf, rate it, or record how far through it they are. The workId is one returned by search_books, get_book or recommend_from_titles. "Finished it, four and a half stars" is one call with readingStatus FINISHED and rating 4.5. Each field given replaces what the reader had there before, so send a rating or a note only when they asked for that one to change. Omitting readingStatus leaves the book on the shelf it is already on.
Input Schema
{
"type": "object",
"properties": {
"workId": {
"type": "string",
"minLength": 1
},
"readingStatus": {
"type": "string",
"enum": [
"NOT_STARTED",
"READING",
"FINISHED",
"DNF"
],
"description": "The shelf to put the book on. Omit to leave it where it is, or NOT_STARTED for a book the reader has not opened yet."
},
"rating": {
"type": "number",
"minimum": 0.5,
"maximum": 5,
"multipleOf": 0.5,
"description": "Stars, 0.5 to 5 in half-star steps"
},
"progress": {
"type": "integer",
"minimum": 0,
"maximum": 100,
"description": "Percent read, 0 to 100"
},
"notes": {
"type": "string",
"maxLength": 2000,
"description": "The reader's own note on the book, private to them"
}
},
"required": [
"workId"
],
"additionalProperties": false,
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢get_my_book(workId)
Whether the signed-in reader has this book on a shelf, and if so which shelf, their rating and how far through they are. Answers "have I read this?" without pulling the whole library.
Input Schema
{
"type": "object",
"properties": {
"workId": {
"type": "string",
"minLength": 1
}
},
"required": [
"workId"
],
"additionalProperties": false,
"$schema": "http://json-schema.org/draft-07/schema#"
}🔴remove_from_library(workId)
Take a book off the signed-in reader's shelves entirely, discarding its shelf, progress and notes. The reader's rating for the book stays. This is removal rather than a shelf change: add_to_library with a new readingStatus moves a book between shelves instead.
Input Schema
{
"type": "object",
"properties": {
"workId": {
"type": "string",
"minLength": 1
}
},
"required": [
"workId"
],
"additionalProperties": false,
"$schema": "http://json-schema.org/draft-07/schema#"
