## Changes things (7)

Creates or changes something that can be changed back. Claude Code: ask.

### `parlayapi_best_bets`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
What should I bet right now? Ranked +EV plays for a sport.

    The discovery counterpart to parlayapi_verdict: scans the whole board,
    grades every candidate with the same no-vig engine, keeps only bets that
    are +EV at a book the user can bet at, and ranks them by edge. Also returns
    edge_alerts (books showing a price far off the market). Player props only,
    priced by several books, prediction markets and game moneylines excluded
    (for a game line, use parlayapi_verdict). Scoped to the user's books.

    Args:
        sport_key: e.g. "baseball_mlb".
        region: us (default) | eu | uk | au | ca.
        books: exact CSV of books you can bet at (overrides region).
        limit: max plays to return (default 20).
        min_edge: minimum edge %% vs the no-vig fair line (default 2.0).
    
```

### `parlayapi_checkout_link`

- The name "parlayapi_checkout_link" says "checkout": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Request an owner-authenticated checkout URL or an email-link flow.

    A configured key is forwarded for the backend to verify account ownership.
    With no matching key, the backend returns an email-flow acknowledgement
    rather than a checkout URL. That response does not confirm email delivery.
    Tiers: starter, pro, business, enterprise, scale. For current prices, call
    parlayapi_get_pricing.
    
```

### `parlayapi_magic_link`

- The name "parlayapi_magic_link" says "link": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Email a magic-login link for an existing ParlayAPI account.

    Always returns ok=true regardless of whether the email exists, to
    prevent account enumeration. The user receives the link by email.
    
```

### `parlayapi_parlay_verdict`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Grade a multi-leg parlay: should you bet it, and at which book?

    Give 2 to 12 legs (each shaped like a parlayapi_verdict bet) and get the
    combined no-vig fair price, the single best BOOK to place the whole slip at
    (a real parlay is one slip, not best-of-each), the parlay's EV, the weakest
    leg, same-game correlation warnings, and (with stake) the payout. Best-price
    is scoped to books the user can bet at (set once via
    parlayapi_set_bettable_books, or pass region/books here).

    Args:
        legs: list of leg objects, e.g.
            [{"sport": "baseball_mlb", "home": "Detroit Tigers",
              "away": "Kansas City Royals", "market": "h2h", "side": "Detroit Tigers"},
             {"sport": "baseball_mlb", "team": "Detroit Tigers",
              "market": "totals", "side": "over", "line": 8.5}]
            Each leg: sport, market (h2h/spreads/totals or a player-prop key),
            side (team, or over/under), home+away or team, player (for props), line.
        region: us (default) | eu | uk | au | ca.
        books: exact CSV of books you can bet at (overrides region).
        stake: optional stake amount, to compute the payout if it hits.
        book: optional, also report the parlay price at this specific book.
    
```

### `parlayapi_set_bettable_books`

- The name "parlayapi_set_bettable_books" says "set": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Remember which books the user can bet at, so parlayapi_verdict scopes its
    best-price and shop recommendations to them automatically (no need to pass
    region/books every call).

    Call this once when a user tells you where they bet ("I'm in the US on
    DraftKings and FanDuel"). Pass region OR an exact books list.

    Args:
        region: us | eu | uk | au | ca.
        books: exact CSV of book keys, e.g. "draftkings,fanduel,novig". Overrides region.
    
```

### `parlayapi_signup`

- The description's first verb is "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Create a free-tier ParlayAPI account for the given email.

    Returns the API key, a magic-login URL the user can click to access
    their dashboard, and a Stripe upgrade URL. Idempotent: if the email
    already has an account, returns exists=true with the login URL only
    (the existing API key is intentionally NOT exposed for security).

    Use this when a user wants to start building with ParlayAPI and
    does not have a key yet. After signup, ask the user to add the
    returned api_key to their MCP server config under PARLAYAPI_KEY,
    then restart the MCP client to pick it up.

    Args:
        email: User's email address.
        intended_use: Optional one-line description of what they're
            building. Used for analytics.
        agent_id: Identifier for the agent making the call. Defaults
            to "mcp-client".
    
```

### `parlayapi_verdict`

- Nothing in its name or description says what it does, so it is counted as a write.
- Findings: info long-description

Description, as the server wrote it:

```untrusted-server-text
Should I bet this? One-call verdict for a specific bet.

    Returns the no-vig fair price for the exact bet, the best available price
    and which book has it, how the user's price (if given) grades as EV, a
    line-shopping nudge, and a plain-English call: BET / LEAN / FAIR / PASS
    (or NO_DATA). Use this when a user asks whether a specific bet is worth
    making, or whether they're getting a good number, instead of stitching
    /ev + /consensus + /best-line yourself.

    The best-price / shop recommendation is scoped to books the user can bet
    at (default US, so a US bettor is never told to use a euro book). Set it
    once with parlayapi_set_bettable_books and it is remembered per key, or
    pass region / books here per call.

    Args:
        sport: sport_key, e.g. "baseball_mlb".
        side: the team you'd bet (h2h / spreads), or "over" / "under" (totals / props).
        market: h2h | spreads | totals | a player-prop key (player_hits, player_points, ...).
        home, away: the two teams, to identify the game. Or pass `team` with one name.
        team: one team name to find the game (alternative to home + away).
        player: player name (required for player-prop markets).
        line: the number for spreads, totals, or props.
        book: the book you'd bet at (grades that book's current price).
        price: the price you're offered (American like -110, or decimal like 1.91).
            Overrides `book`, use it to grade a specific number in hand.
        region: where you can bet: us (default) | eu | uk | au | ca.
        books: exact CSV of books you can bet at (overrides region; use for
            state-level geo-blocks, e.g. "draftkings,fanduel,novig").
        bankroll: the user's bankroll; when the bet is +EV, returns a suggested
            Kelly stake amount ("bet it, ~$X").
        kelly: Kelly fraction (default 0.5 = half-Kelly, the bankroll-safe standard).

    The response also carries an `edge_alert` when a book shows a price far
    better than the market (a possible soft error worth grabbing, or a stale
    line to verify) that the normal best-price guard would otherwise hide.
    
```

Description, as the server wrote it:

```untrusted-server-text
Find cross-book arbitrage candidates from current quoted prices.

    Scans every event for quoted prices whose combined implied probability
    is under 100%. Results are candidates, not guaranteed executable profit:
    prices can move or be unavailable, and limits, latency, commissions,
    voids, settlement rules, or stake constraints can change the outcome.
    Soccer and other 3-way (home/draw/away) markets are supported, including
    candidates anchored on the draw.

    Args:
        sport_key: e.g. "baseball_mlb", "soccer_epl".
        min_profit: Minimum profit % to include (e.g. 1.5 for 1.5%). Default 0.
        exclude_exchanges: Drop arbs anchored on an exchange (novig/prophetx),
            whose asks can be no-volume. Default False.
        markets: Comma-separated market_keys to limit the scan (optional),
            e.g. "h2h,spreads,totals".

```untrusted-server-text
Find positive-EV bets vs a sharp book's no-vig fair line.

    Compares every soft book's price against the no-vig fair probability
    derived from a sharp book (default Pinnacle); rows where a soft book
    offers better odds than the sharp fair price are +EV. Three-way soccer
    markets use a dedicated no-vig pass over home/draw/away, so +EV on the
    draw surfaces too.

    Args:
        sport_key: e.g. "baseball_mlb", "soccer_epl".
        sharp_book: Sharp baseline book. Default "pinnacle".
        min_edge: Minimum edge % to include (e.g. 3 for 3%). Default 2.
        markets: Comma-separated market_keys (optional).
    
```

### `parlayapi_find_middles`

- The name "parlayapi_find_middles" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find cross-book middle opportunities.

    A middle takes the Over at a low line on one book and the Under at a
    higher line on another, so a window of whole numbers cashes BOTH bets
    (e.g. Over 7.5 at one book, Under 9.5 at another means 8 or 9 wins both).
    Scans game totals, spreads, AND player-total props (points, rebounds,
    strikeouts, ...). Each result carries the window, the numbers that hit,
    and per-$100 economics: profit_if_hit and net_if_above/below_window.

    Args:
        sport_key: e.g. "baseball_mlb", "basketball_nba".
        min_gap: Minimum window width in points/runs/goals. Default 1.0.
        markets: Comma-separated market_keys to limit the scan (optional),
            e.g. "totals" or "player_points".
        include_props: Include player-total props alongside game lines. Default True.
    
```
