#advertising

API de matemáticas de métricas de marketing digital, calculadas local y determinísticamente. El endpoint ads calcula KPIs de campaña a partir de dos de los siguientes: gasto, impresiones, clics y conversiones: el CPM (costo por mil impresiones), el CPC (costo por clic), el CTR (tasa de clics), la tasa de conversión y el CPA (costo por adquisición). El endpoint roas calcula el retorno de la inversión publicitaria, ROAS = ingresos ÷ gasto, el porcentaje de ROI y la ganancia bruta, y — dado un margen bruto — el ROAS de equilibrio de 1 ÷ margen. El endpoint ltv calcula el valor de vida del cliente, valor promedio del pedido × frecuencia de compra × vida útil × margen bruto, y, con el gasto de marketing y el número de nuevos clientes, el costo de adquisición de clientes, la importantísima relación LTV:CAC y el período de recuperación del CAC en meses. Todo se calcula local y determinísticamente, por lo que es instantáneo y privado. Ideal para desarrolladores de aplicaciones de marketing, publicidad, comercio electrónico y crecimiento, paneles de campaña y herramientas de informes, y calculadoras de agencias. Cálculo local puro — sin clave, sin servicio de terceros, instantáneo. En vivo, nada almacenado. 3 endpoints. Esto son matemáticas de métricas de marketing; para matemáticas de porcentajes use una API de porcentajes y para conversión de divisas use una API de divisas.

Marketing and advertising metrics as an API — the everyday campaign maths, computed locally and deterministically and entirely currency-agnostic. The funnel endpoint takes any of impressions, clicks, conversions, spend and revenue and computes every metric the inputs allow: click-through rate (CTR), cost per click (CPC), cost per mille (CPM), conversion rate, cost per acquisition (CPA), average order value, return on ad spend (ROAS), return on investment (ROI) and profit — anything not derivable is returned as null rather than guessed. The roas endpoint focuses on profitability: ROAS, ROI and profit, and — given a gross margin — the break-even ROAS and gross profit, with a profitable flag. The target endpoint reverse-plans a campaign: from a conversion or revenue goal and your known rates it works out the required clicks, impressions and budget and the expected revenue and ROAS. Everything is computed locally and deterministically, so it is instant and private. Rates such as conversion_rate and ctr are given as fractions (0.05 = 5%). Ideal for marketing dashboards and reporting, media-buying and bid tools, agency and campaign planners, and e-commerce analytics. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is advertising-metric maths; for loan and investment maths use a finance-calculator API.

Fetch and evaluate any publisher's ads.txt / app-ads.txt — the IAB authorized-digital-sellers standard. Pass a domain and the check endpoint fetches its ads.txt server-side, then returns every seller record parsed into its fields — advertising system, the publisher's seller/account id, the DIRECT or RESELLER relationship and the optional certification-authority id (TAG-ID) — alongside counts (direct, reseller, distinct ad systems) and the declared variables OWNERDOMAIN, MANAGERDOMAIN, CONTACT and SUBDOMAINS. The verify endpoint answers the one question programmatic-advertising integrations actually ask: is this advertising system, with this publisher id, authorized to sell this domain's inventory? — returning an authorized boolean and the matching records. A missing file is reported as found:false (not an error), and soft-404 HTML pages are detected and rejected so you never parse a "page not found" as records. The request is made server-side and private or internal targets are refused (SSRF-guarded). Built for ad-tech supply-chain verification, SSP/DSP onboarding checks, anti-fraud and inventory audits. An ads.txt seller-authorization checker — distinct from the security-contact file reader (securitytxt), the robots.txt crawlability evaluator (robots) and the sitemap parser (sitemap). No upstream key, no cache.
