FizzRead — AI Book Summaries & Audio Previews

Instant access to 100K+ nonfiction book summaries with 1-minute audio previews. Free demo key included — start exploring immediately. Get daily recommendations, search by keyword, browse categories, and listen — all inside your conversation.

Setup

Built-in Demo Key: This skill includes a free demo API key so everyone can try it immediately — no signup required.

Demo key: 3272ed72f9d0b120706038f94220770b

API Key Resolution Order

When making API calls, determine the API key using this priority:

1. Environment variable FIZZREAD_API_KEY — if set, always use it
2. Demo key (3272ed72f9d0b120706038f94220770b) — use as fallback when no env var is set

First-time Setup Flow

On first use, check if FIZZREAD_API_KEY is set by running:

echo "$FIZZREAD_API_KEY"

If set and non-empty: Use it directly. Run a quick connectivity test with the Daily Pick endpoint and show the result.

If not set (empty): Use the demo key and show today's book. Then append this guidance:

> You're using the free demo key. For your own key with higher rate limits:

>

> 1. Visit fizzread.ai and sign up

> 2. Go to Settings > API Keys > Generate

> 3. Add it to your system environment to persist across sessions:

>

> macOS / Linux — add to your ~/.bashrc or ~/.zshrc:

> ```bash

> export FIZZREAD_API_KEY="your_key_here"

> ```

> Then run source ~/.zshrc (or restart terminal).

>

> Windows — run in PowerShell:

> ```powershell

> [System.Environment]::SetEnvironmentVariable("FIZZREAD_API_KEY", "your_key_here", "User")

> ```

> Then restart terminal.

When the user provides a key manually

If a user pastes a key during conversation, run a connectivity test:

curl -s -H "Authorization: Bearer {user_provided_key}" "https://skill.fizzread.ai/v1/daily"

• If the response contains data.title, the test passed. Remember this key for all subsequent API calls in this session. Also guide the user to save it as an environment variable (using the instructions above) so it persists across sessions.
• On 401: "This API key appears to be invalid. Please double-check and try again."
• On network failure: "Could not connect to FizzRead API. Please check your network connection and try again."

Important: Once a key is determined (from env var, demo, or user-provided), remember it and substitute it directly into the Authorization: Bearer header of every subsequent curl command. Do not rely on shell environment variables persisting between commands.

Base URL: https://skill.fizzread.ai/v1

All requests must include the header:

Authorization: Bearer <the resolved API key>

Daily Pick

When the user asks for a daily book recommendation (e.g. "recommend a book", "today's book", "daily pick"):

1. Run:

```bash

curl -s -H "Authorization: Bearer $FIZZREAD_API_KEY" "https://skill.fizzread.ai/v1/daily"

```

1. Parse the JSON response. All API responses wrap data in a data field (e.g. {"data": {...}}). Extract fields from data and output using this template:

```

📖 Today's Pick

{title} by {author}

{about}

---

Full 10-min audio free on FizzRead App 👉 {download_url}

🎧 1-min Audio Preview (English)

```

• If the user's language is not English, translate the about field to the user's language. Keep title and author in the original English.
• If audio_url is null, omit the audio line entirely.
• Always mark audio as "(English)" since all audio content is in English.
• Do NOT output cover_url as a raw URL. The book cover will be shown automatically via Telegram's link preview of the app_url.

Book Search

When the user wants to search for books (e.g. "search for atomic habits", "find books about productivity"):

1. Extract the search keyword from the user's message.

1. URL-encode the keyword to prevent shell injection and handle special characters. Replace spaces with %20, and encode any special characters.

1. Run:

```bash

curl -s -H "Authorization: Bearer $FIZZREAD_API_KEY" "https://skill.fizzread.ai/v1/search?q={encoded_keyword}&limit=5"

```

If the user explicitly asks for books with audio only, append &audio_only=true.

1. Parse the JSON response. Extract data.results and data.total. If results is empty, tell the user no books were found and suggest trying different keywords.

1. Output as a numbered list:

```

Found {total} books for "{keyword}":

1. {title} — {author}

{about, first sentence only}

1. {title} — {author}

{about, first sentence only}

...

• If the user's language is not English, translate each about excerpt.
• When the user replies with a number, use the corresponding slug to call the Book Summary flow below.

Book Summary

When the user asks for a specific book's summary (e.g. by selecting from search results, or naming a book directly):

1. Determine the book's slug. If you have it from a previous search, use it directly. Otherwise, first search for the book to find the slug.

1. URL-encode the slug before using it in the URL.

1. Run:

```bash

curl -s -H "Authorization: Bearer $FIZZREAD_API_KEY" "https://skill.fizzread.ai/v1/book/{slug}"

```

1. Parse the JSON response. Extract fields from data and output:

```

📖 {title}

Author: {author}

{about}

• If the user's language is not English, translate the about field.
• If audio_url is null, omit the audio line.
• Do NOT output cover_url as a raw URL. The cover shows via Telegram link preview of app_url.

Category Recommendations

When the user asks for books by category or topic (e.g. "recommend psychology books", "what productivity books do you have"):

1. Extract the category/topic from the user's message.

1. First, fetch available categories:

```bash

curl -s -H "Authorization: Bearer $FIZZREAD_API_KEY" "https://skill.fizzread.ai/v1/categories"

```

1. Fuzzy-match the user's requested topic against the returned data[].name list. Pick the closest match. If no reasonable match exists, tell the user the available categories and ask them to pick one.

1. URL-encode the matched category name.

1. Fetch recommendations:

```bash

curl -s -H "Authorization: Bearer $FIZZREAD_API_KEY" "https://skill.fizzread.ai/v1/recommend?category={encoded_category}&limit=5"

```

1. Output as a numbered list (same format as Book Search results):

```

Top books in {category} ({count} books available):

1. {title} — {author}

{about, first sentence only}

...

Output Rules

1. Language: Detect the user's conversation language. If not English, translate about content to the user's language. Keep book titles, author names, and audio labels in English.

1. Audio: All audio is in English. Always label audio links with "(English)" so non-English users know what to expect.

1. No fabrication: Only use data returned by the API. Never invent book titles, summaries, or URLs. If the API returns an error or empty result, say so honestly.

1. CTA (Call to Action): Every response that includes book data must end with a download link to the FizzRead App. Use the download_url from the API response.

1. Audio handling: When audio_url is null for a book, simply skip the audio section — do not mention that audio is unavailable.

1. Cover image: NEVER output cover_url as a raw URL or text. Instead, embed app_url as a hyperlink on the book title: {title}. Telegram will auto-generate a link preview card with the book cover from the page's og:image metadata. This is the only way to display covers.

Error Handling

When an API call returns an error, respond with a friendly message:

• 401 Unauthorized: "Your FizzRead API key appears to be invalid. Please check your FIZZREAD_API_KEY and try again. Get a new key at fizzread.ai."

• 404 Not Found: "That book wasn't found in the FizzRead library. Try searching with different keywords."

• 429 Too Many Requests: "You've made too many requests. Please wait a moment and try again."

• 500 / other errors: "FizzRead is temporarily unavailable. Please try again in a few minutes."

• Network / curl failure: "Could not reach the FizzRead API. Please check your network connection and try again."
