Firecrawl Alexandria adds fantasy football data for AI agents

What the lineup tool does

Firecrawl describes the problem as a familiar one: setting a fantasy football lineup usually means checking rankings on one site, projections in another scoring format elsewhere, and the injury report on a third. None of those sites know who is on your roster, so the user lines everything up by hand, often right before kickoff.

With the new fantasy pack, an agent can read the league, pull this week's projections for the user's players in the league's scoring format, check injury reports and player news, and say who to start. Firecrawl says Alexandria is already live in Claude, ChatGPT, Codex and other agent tools.

Firecrawl offers buttons that open a chat in ChatGPT or Claude with the prompt ready. The agent then:

• Gives a link to add the Firecrawl plugin if it is not connected yet.
• Asks for a Sleeper username, an ESPN or Yahoo league link, or a screenshot of the roster.
• Pulls this week's projections from every fantasy source in Alexandria, in the league's scoring format.
• Tells the user who to start and sit in real lineup slots, with one line of reasoning per change, then names the top three free agents worth adding.

Users who prefer not to open a chat can use a free fantasy lineup page. It accepts a Sleeper username, a pasted ESPN or Yahoo team page, or a screenshot, and ranks the roster with no account. According to Firecrawl, the roster stays in the browser.

What data is included

The pack combines several kinds of data, and each can also be called by an agent on its own.

• Weekly projections and rankings: start/sit order and projected points for QB, RB, WR, TE, K and team defense from six expert sources, in PPR, half-PPR and standard scoring. Not every source covers every position and format, and some add floor and ceiling projections, tiers and stat lines.
• Projections from betting lines: projected points built from sportsbook player props, with the consensus line behind each number.
• Season and rest-of-season boards: long-range rankings for trades and waivers, plus dynasty and rookie rankings and average draft position.
• Injuries and news: the weekly injury and practice participation report, and the latest news for a player.
• League and schedule data: weekly schedules and scores, rosters, standings and player profiles.
• Accuracy checks: last week's projected versus actual points.

The lineup tool merges the projections from all six sources by player and shows the consensus next to the range. Firecrawl explains that a narrow range means the sources agree, while a wide one means the call is close and the matchup matters more. For that reason the tool grades each opponent by how many fantasy points it has allowed to that position.

Use cases and how agents call the data

Firecrawl lists several requests a user can make to an agent in ChatGPT, Claude or Codex: settling a start/sit call by comparing players across every source and checking the injury report; working the waiver wire against rest-of-season projections; planning a trade using season-long projections and remaining schedules; checking how last week's projections held up; and preparing for next year's draft with average draft position by scoring format and league size, including past seasons.

Users do not need to know capability names in advance. Describing the data wanted makes Alexandria return matching capabilities, ranked, with inputs and prices attached. Firecrawl's example is a search call with sources set to web and alexandria, using the query "half-PPR running back projections for this week". The same discovery works from Claude, Cursor, Codex and other tools that connect over MCP, or from the CLI.

Agents use a single Firecrawl key and pay in Firecrawl credits at the price listed on each capability. Firecrawl says there is no separate key per site and nothing to scrape or parse. Discovering capabilities is free, and each one shows its price in credits before it is called.

What it means and what comes next

For fantasy players, the change moves the cross-checking of rankings, projections and injury news from several sites into one request to an agent that can also see the roster. For developers, it offers a way to reach many data sources through one key and a consistent listing of inputs, response shape and price.

Firecrawl says the sports category in Alexandria already goes beyond fantasy football, with league data across the NFL, NBA, MLB, NHL, college sports and soccer, plus prediction markets and ticket prices. According to the company, new providers join every week across 26 categories.
