Tools as reported by the server

• get_started
  Start here with a new user. Returns the short set of questions to ask them (game, format, stakes, goal), a menu of what PokerData can do with the tools for each, what is free without a key, and how to file a feature or data request. Free, no key needed.
• submit_request write/delete
  File a feature request or data request for the user, after telling them their question isn't covered and they agree. kind "data" is missing coverage (a game, format, stack depth, spot, or solve); kind "feature" is a missing capability (a tool, filter, export, or endpoint). Free with any key; the Pok
• list_my_requests
  List the feature and data requests this account has filed, newest first, with their status. Free with any key.
• list_games
  Discover covered stack depths and positions. Call this before low-level preflop queries. "nl" = no-limit hold'em 6-max cash (169-grid hands, per-hand EV in small blinds), "nl9" = no-limit hold'em 9-max cash, "nlmtt8" = no-limit hold'em 8-max MTT chip-EV (10–300bb, 1bb BB-ante; Fold/Call/Limp/AI/Open
• get_range
  The GTO range for one spot. `spot` is an action path of POSITION_ACTION pairs ending in the action whose range you want, e.g. NLHE cash "UTG_60%_HJ_Call", nlmtt8 "UTG_Open", or PLO "UTG_Open_HJ_3B". Add `hand` for one exact frequency and EV. Compact mode is default; PLO returns representative pure/m
• get_node
  Actions available at a decision node. `history` is an action path ending in the position about to act, e.g. "UTG_60%_HJ". sizeBb is the raise-to in big blinds and sizePctPot is the percent of the pot after calling (nlmtt8 40bb Open 40034 is 2.19bb; the pack label is 2.2x). evs are small blinds relat
• get_config
  Table for one preflop game and stack, in big blinds: seats, stacks, blinds (sb 0.5, bb 1), ante, antePostedBy, stackIncludesAnte, openSizes (first-in raise-to), evUnit, evBaseline. Convergence is not published. stackIncludesAnte is true: the named depth is the starting stack and the 1bb BB ante is p
• list_spots
  Search valid decision nodes for a stack depth, tagged by depth (1 = RFI, 2 = vs open, 3 = 3-bet pots, …). Compact mode is paginated; use depth, contains, and offset to narrow results without loading thousands of paths. plo9 has no spot index: walk it with get_node from history "UTG".
• list_postflop_packs
  Every solved postflop pack: preflop line, positions (OOP vs IP), stack, pot, the bet-size trees it is solved under, and the solved boards. Boards use the spaced form ("3h 3d 2s"). NLHE packs list `sizingTrees`: "75" (75% pot every street, the pack id itself) and "33" (33% pot on the flop, then 75%,
• get_postflop_node
  One postflop solver node: the acting player's strategy for every hand class, the legal next segments, board, reach and the reach-weighted action split. Walk deeper by appending a returned childSegment (an action like "Bet 5.5" or a runout like "deal:7c") to `path`.
• explain_combo
  Preferred tool for exact NLHE postflop hand questions. Returns a canonical context, exact action mix, action EV/loss when available, made-hand and draw classification, blocker facts, and same-rank-class suit comparisons. The server computes evidence; the agent should phrase causality as interpretati
• get_board_report
  Preferred tool for board-texture heuristics. Aggregates action frequencies and range/action composition across solved boards in one postflop pack. Results explicitly report sample breadth and use equal weight per board.
• compare_strategies
  Preferred tool for differences between two preflop or postflop contexts. The server fetches both strategies and returns action-frequency/EV deltas plus the largest postflop combo changes, avoiding two large node payloads.
• list_datasets
  List preflop datasets in the shipped tree documentation (stacks, positions, whether each bundle was analyzed). Preflop exploitability is not available.
• get_tree_docs
  Tree documentation for one dataset: coverage note from the shipped README and per-stack bundle or node counts from the shipped index. Does not read or modify range bytes.
• get_range_metadata
  Index metadata for one preflop game, stack, and path: bundle stats for hold'em/PLO bundles, or the matching node row for plo5 and plo6hu. Does not return a strategy and does not invent exploitability.
• get_exploitability
  Preflop exploitability for a game. No preflop dataset publishes exploitability, convergence, or iteration counts. The answer is not available; this tool never fills in a number.
• get_postflop_range
  The range a player takes one flop action with, from a solved pack: hand-class weights ("AA:1,AKs:0.42,...", same format as the preflop ranges) after every earlier flop action on the path. `path` ends in the action whose range you want, e.g. ["Check", "Bet 1.8", "Call 1.8"] for the check-call range.
• find_hands
  Find hands the account has uploaded. Returns hand_id, session_id, handAt, position, cards, game, board, potType, street lines, and netBb. Solver grade buckets are not filled. If this account has no hands, offer the hosted upload page from get_upload_link (https://pokerdata.io/upload) instead of aski
• get_hand_results
  Per-hand cumulative results for a winnings curve. `points` is [{ hand, bb }], oldest to newest, downsampled. Pass session_id for one session. If this account has no hands, offer the hosted upload page from get_upload_link (https://pokerdata.io/upload) instead of asking the user to paste histories in
• get_session_summary
  One uploaded session's headline numbers: hero, game type, start and end times, hands played, net result in big blinds, and HUD rates (VPIP, PFR, 3-bet, open limp) as percentages with the sample size. Use it after list_my_sessions to report how a session went; use get_hand_results for its winnings cu
• list_my_sessions
  Recent uploaded sessions, newest first: id, hero, game type, dates, hands, and net result. game_type matches hole-card count. If this account has no hands, offer the hosted upload page from get_upload_link (https://pokerdata.io/upload) instead of asking the user to paste histories into chat.
• get_tournament_results
  MTT results imported from tournament summary files. Money is in cents. Hand histories are not a source of buy-ins or prizes. If this account has no hands, offer the hosted upload page from get_upload_link (https://pokerdata.io/upload) instead of asking the user to paste histories into chat.
• list_my_opponents
  Tracked opponents from uploaded hands. Each row has handCount, handsVsHero, and heroBb100Vs. Pass name to find one villain.
• get_opponent_notes
  Leak notes computed from uploaded hands for one opponent, with the sample size on each line.
• get_opponent_limp_range
  Shown-hand first-in limp range: 169-class counts of hole cards villains showed after an open limp. Pass position for one seat. Sample is showdown-only. This is not a solver range.
• enqueue_solve write/delete
  Record a heads-up postflop solve request. Required: title, board, pot (bb), effective_stack (bb). The job stays pending: solver dispatch and billing are not configured, so this does not start a solve.
• get_queued_solve
  Look up one queued solve for this account. status is pending, running, done, or failed. solution_id is null until a worker exists.
• list_queued_solves
  List this account's solver-queue jobs, newest first. Jobs are not dispatched.
• list_library_solutions
  Finished postflop solutions saved for this account. None are marked done while dispatch is disabled.
• get_upload_link
  Primary hand-upload path. Returns https://pokerdata.io/upload on this origin, with a short-lived signed token for the caller's account when signing is configured. Hand the URL to the user. Pasting histories into chat is the fallback.
• upload_hand_history write/delete
  Secondary upload path for a small paste. Prefer get_upload_link and the hosted /upload page. Runs the same ingestion pipeline and returns hands parsed, tournaments parsed, and errors. Does not grade solver frequencies.
