OpenAPI specification · Resolved tool schemas
WebMCP registers the seven tools on this page when supported by the browser. Calculations run locally using the same code as the calculators.
Browser support varies; the JSON APIs are also available.
HTTP API calls send the supplied values to the server. WebMCP tool calls do not send inputs to the server or read saved calculator inputs.

Each ZIP includes instructions, scripts and a first exercise. Install it in a compatible assistant that can run the scripts, then review its findings before acting.
This directory covers public content and tools. The text and catalogs rebuild with the site; unreleased lesson bodies and confirmation pages are excluded.
Using the content and results
Keep source URLs, reporting dates and limitations with any summary. Case-study snapshots show reported account results; they do not establish incremental lift. Teaching examples and practice files are illustrative. Tool results depend on the supplied costs, report scope and model assumptions.

Open a tool for its purpose, limits and an example request. Schemas are generated from the existing API specification.
Catalog Profit Check
Which products lose money on ads? Up to 500 products
Limits: Rates are fractions: 0.30 means 30%. Contribution estimates require complete supplied costs; they are not net business profit. Inspect per-product errors even when the batch call succeeds.

When to Negate
Check one search term, or up to 500
Limits: Single-term binomial evidence under supplied assumptions. Statistical evidence is not certainty or proof of wasted spend.

Harvest Readiness
Send one term's fields, or { defaults, terms: [...] }. Defaults apply to every term unless the term overrides them.
Limits: Single-term, uncalibrated model. Does not estimate incremental profit from harvesting or guarantee future performance.

Placement Bid Calculator
A click in each placement is worth (sales ÷ clicks) × target ACoS. Returns two options: rebalance (the weakest placement sets the keyword bid) and keep today's keyword bid. Placements under 30 clicks don't set bids. Docs: https://profitfirstppc.com/tools/placement-bid-calculator/
Limits: Rates are fractions. Low-evidence placements and minimum-bid exceptions need review; no Amazon settings are changed.

Search Term Report Checker
Pure report analysis. No file upload or storage. Optional sales must use the same purchase attribution window. One currency per request. Orders greater than clicks remain descriptive and skip probability models. Bulk exact-keyword inventory is browser-only. Zero-order spend is not confirmed waste.
Limits: At most 500 normalized rows. Zero-order spend is not confirmed waste. Same report context and attribution definitions are caller prerequisites.

ACoS Change Explainer
Six-order averaged arithmetic bridge for ACoS change. Same scope and attribution definitions must be checked by the caller. Not a causal diagnosis.
Limits: An arithmetic allocation, not a causal diagnosis. Compare consistent scope, currency and attribution definitions.
