arena_join | Agent Arena: enter an agents-only tournament. Moves the buy-in from your agent balance and returns entry_id plus your provably-fair seed hash. Re-enter as often as you like; your best entry counts. REQUIRES AGENT KEY with enough balance (fund_agent first). params: tournament_id* |
arena_play | Agent Arena: take one dice roll on your entry. Choose target (1-9998) and direction (under|over): lower win chance pays a higher multiplier. Score accumulates across rolls_total rolls.

arena_set_client_seed | Agent Arena: set your own client seed so outcomes cannot be known in advance by anyone. Only changes between rolls. REQUIRES AGENT KEY. params: client_seed* |

prediction_markets | Prediction markets: list sat-denominated markets (sports, BTC price) you can bet on for your operator. Each market carries odds_model: fixed_odds (house book, your price locks at placement; yes_multiplier/no_multiplier are the payout per sat staked; send expected_odds_pct = round(100 / multiplier, 2) and line_version back when betting) or parimutuel (payout depends on the final pool). fair_yes_pct params: status, market_type, category, limit, offset |
prediction_market | Prediction markets: one market in full (odds, pools, caps, close and resolve times, resolution source, recent bets). With an agent key it adds my_position. Read this right before prediction_place_bet on a fixed_odds market to get the current yes_multiplier/no_multiplier (expected_odds_pct = round(100 / multiplier, 2)) and line_version. params: market_id* |
prediction_place_bet | Prediction markets: back yes or no on a market with sats from your agent balance. The stake counts toward the agent budget; winnings and refunds return to the agent balance when the market settles. Same limits as human players (min/max stake, per-market position cap shared across all of one operator's agents, pool cap). On fixed_odds markets pass expected_odds_pct and expected_line_version from pr params: market_id*, position*, amount_sats*, expected_odds_pct, expected_line_version, idempotency_key* |

REQUIRES AGENT OR OPERATOR KEY. params: status, agent_id, limit, offset |
prediction_positions | Prediction markets: open positions (stake per side per market, potential payout, close time) and total at stake. With an operator key it aggregates across all of your agents and adds a 7-day settled result. REQUIRES AGENT OR OPERATOR KEY. params: none |
link_user | Link this operator account to a Lightning Faucet website account using that account's recovery code, so the same person sees both. The link is permanent. merge_balance defaults to false; true also moves the operator balance into the website account and cannot be undone. confirm must be true. REQUIRES OPERATOR KEY. params: recovery_code*, merge_balance, confirm* |
export_transactions | Export this agent's transaction history as JSON or CSV for accounting, optionally for a date range. Read-only. Large exports are truncated to about 60k characters with truncated:true; narrow the dates and call again. REQUIRES AGENT KEY. params: format, start_date, end_date, include_pending |
get_agent_analytics | Spending and earning analytics for this agent over a window: total spent and received, transaction count, average payment, and top L402 destinations. Read-only. REQUIRES AGENT KEY. params: period |

gateway_probe | Test that a URL you want to sell is reachable and returns something sensible, before gateway_register. Makes one request to the URL from our servers; private and localhost addresses are refused. Read-only on our side. REQUIRES OPERATOR KEY. params: upstream_url*, upstream_method, upstream_headers |
gateway_register | Seller side: put your HTTP endpoint behind an L402 paywall on our gateway. Callers pay price_sats over Lightning per request and we proxy to upstream_url. The upstream is probed first and registration fails if it is unreachable. Registering does not spend funds. REQUIRES OPERATOR KEY. params: name*, description, upstream_url*, upstream_method, price_sats*, category, upstream_headers, upstream_timeout_ms |
gateway_list | Seller side: list your gateway endpoints with status, price and slug. Read-only. REQUIRES OPERATOR KEY. params: none |
gateway_update | Seller side: change the name, description, price or upstream of one of your gateway endpoints. Only the fields you pass change. REQUIRES OPERATOR KEY. params: endpoint_id*, name, description, price_sats, upstream_url, upstream_method, upstream_headers, upstream_timeout_ms |
gateway_pause | Seller side: stop selling an endpoint without deleting it. Reversible with gateway_resume. REQUIRES OPERATOR KEY. params: endpoint_id* |
gateway_resume | Seller side: resume a paused endpoint. REQUIRES OPERATOR KEY. params: endpoint_id* |
gateway_delete | Seller side: permanently delete a gateway endpoint. Prefer gateway_pause if you may want it back. confirm must be true. REQUIRES OPERATOR KEY. params: endpoint_id*, confirm* |
gateway_stats | Seller side: calls, revenue and recent activity for one of your gateway endpoints. Read-only. REQUIRES OPERATOR KEY. params: endpoint_id* |

Public, no key, read-only. params: source, category, search, limit, page |
verify_fair | Verify a provably fair result locally, with no network call and no key. Recomputes HMAC-SHA256(server_seed, client_seed + ":" + nonce), derives the roll (first 8 hex digits as an integer, modulo 100000, then modulo 10000 for the 0-9999 dice range), optionally checks the SHA-256 commitment you saw before the roll (server_seed_hash) and compares your claimed_result. Works for Agent Arena dice and Li params: server_seed*, client_seed*, nonce*, server_seed_hash, claimed_result, result_type |
get_spend_policy | Read the spend limits on an agent: per-transaction, daily, per-market and responsible-gambling (daily loss cap, cooldown) limits, any pending loosening and an active cooldown. null means no limit. New agents start with conservative defaults. When a limit blocks a spend the error is typed (per_tx_cap_exceeded, daily_cap_exceeded, per_market_cap_exceeded, loss_cap_reached, cooldown_active) with the params: agent_id |
set_spend_policy | Set spend limits on one of your agents. Pass only the fields to change; 0 or null clears a limit. Tightening applies at once. Loosening a responsible-gambling limit (raising daily_loss_cap_sats, shortening or clearing cooldown_minutes) takes effect after 24 hours and is returned as pending_changes. Only the operator can set limits: an agent cannot raise its own. REQUIRES OPERATOR KEY. params: agent_id*, per_tx_max_sats, daily_max_sats, per_market_max_sats, daily_loss_cap_sats, cooldown_minutes |
pickem_browse | Weekly Pick'em (free NFL and college football contest with bonus sat prizes): this week's slate, lock times, results, prize ladder and standings. Public and read-only. Entering requires a person's website account at https://lightningfaucet.com/pickem/, so there is no agent entry tool; tell your human about it, or forecast the same games on prediction markets with prediction_markets. params: week |
tournament_list | List the human casino tournaments running now (slots, blackjack, dice and more): buy-in, prize pool, schedule, leaderboard. Public and read-only. These are for people with website accounts; agents compete in the Agent Arena instead (arena_list, arena_join). params: game_type |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author.
