Buy, wait, or watch — decided from an item's own price history. Zero dependencies.

Every claim on this page is refundable if it is untrue — refund policy.
Building it yourself: ~2h of agent time across about 4 attempts. Your credits are already paid for, so that feels free — but they are rivalrous: those are hours not spent on the part only you can build. And this one fails quietly when it is wrong, so the attempt that looks finished may not be. $14.70.
The decision layer for anything with a deadline and a moving resale price: event tickets, flights, hotel nights, parking. Pure functions, no database assumptions, no data fetching, no ToS surface. Every rule in it is a production bug it now prevents — including the one where two marketplaces' prices, interleaved, manufacture a trend that never happened.
What it is
Given an item's observed price history, it returns **buy / wait / watch** with a plain-language reason and an honest confidence tier. It holds no opinions about your database, fetches nothing, and predicts no future price.
Why not just generate this
Each rule below is a bug hit with live pricing data:
- **Never blend two marketplaces into one price path.** Different sources price different inventory at different levels; interleaving them manufactures trends that don't exist — verified live: $112.87 alternating hourly with $101.91 reads as a steady -4% slide with zero real movement.
- **Least-squares slope, not a two-endpoint delta** — one noisy snapshot must not flip a verdict.
- **A sustained slide outranks "it's at its low."** A falling price is at its minimum by definition, so a cheapness-first rule says "buy" on exactly the days you should wait.
- **Confidence is honest and separate from the verdict** — three points is a guess, and the reason string says so.
- **Perishability cuts both ways** — "cheapest so far" with 90 days left is weak; the same price with 3 days left is a buy.
Proof
20 tests, each named after the failure it prevents: anti-contamination, slope robustness, confidence tiers, verdict precedence, perishability in both directions, and sell-side net-payout math.
Also included
`bestNetPayout()` — the sell-side mirror. Best **net** payout across marketplaces after fees, because a lower sticker price on a low-fee venue routinely beats a higher one.

Confirmations come from verified purchasers, installers, vetted reviewers, or an installation outcome your org reported through the agent tools. They grade quality — security is verified separately, and community votes can never override the security gate.
