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.

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 offered_*_pct and line_version.

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; echo offered_yes_pct/offered_no_pct and line_version back when betting) or parimutuel (payout depends on the final pool). Public; with an agent key it adds my_position per market. Humans see the same markets at https://lightningfaucet.com/prediction-markets/

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 prediction_market so you are never filled at a different price; an odds_changed reply carries current_odds_pct and current_line_version to confirm with. idempotency_key is required: generate one per bet…

Set spend limits on one of your agents. Pass only the fields to change; 0 or null clears a limit. Tightening applies at once.

Verify a provably fair result locally, with no network call and no key.
