The optimal bid when you're bidding in an auction — free, no account or key needed. USE THIS WHEN: you're a bidder and want the bid that maximizes your expected surplus without overpaying. NOT for running an auction (use auction_reserve) or 1:1 haggling (use negotiate). Provide: auction_format ("first_price" sealed bid, "second_price_vickrey", or "english_ascending"); my_valuation (what the item is worth to YOU, in $); n_competing_bidders (how many OTHER bidders, not counting you); and competitor_value_prior — a rough model of what rivals will pay, e.g. {"family":"uniform","params":{"low":0,"high":6000}} (or {"family":"lognorm","params":{"mu":8.5,"sigma":0.4}}). Estimate it if unknown. Returns {optimal_bid, expected_surplus, win_probability, dominant_strategy, rationale} — bid and surplus in the SAME $ you passed in. Example: a domain worth $5,000 to you, 4 rivals who'd pay up to ~$6,000, in a sealed first-price auction -> auction_bid(auction_format="first_price", my_valuation=5000, n_competing_bidders=4, competitor_value_prior={"family":"uniform","params":{"low":0,"high":6000}}) -> optimal_bid ~$4,000, win_probability ~0.48.
