Media Bias API

Political-bias and factual-reporting ratings for 1,350+ news sources, sourced from AllSides and Media Bias/Fact Check. Look up any outlet by domain or name to get its left/center/right political lean (5-point scale) and high/mixed/low factual reliability — ideal for news aggregators, media-literacy tools and content moderation.

Baking Pan Scaler API

Baking-pan maths as an API, computed locally and deterministically — the area and scale-factor numbers a baker resizes a recipe between pans with. The trick everyone gets wrong is that a recipe scales by the pan’s AREA, not its diameter, so a 10-inch round holds far more batter than a 9-inch. The area endpoint gives the surface area of any pan — round and springform as π/4·d², square as s², rectangle as length × width, and bundt or tube pans as the ring (the outer circle minus the centre hole) — so a 9-inch round is 63.6 in², an 8-inch square 64 and a 9×13 is 117; add a depth and it returns the volume in cubic inches and cups. The convert endpoint gives the scale factor to move a recipe from one pan to another, factor = target area ÷ source area: a 9-inch round to a 9×13 is ×1.84, and two 8-inch rounds really do equal one 9×13. Pass an ingredient amount and it scales it for you, with a note to keep the batter depth similar and adjust the bake time. Everything is computed locally and deterministically, so it is instant and private. Ideal for baking, recipe, meal-prep and kitchen app developers, recipe-scaling and substitution tools, and culinary software. Pure local computation — no key, no third-party service, instant. Inches. Live, nothing stored. 2 compute endpoints. For ingredient unit conversion use a cooking API.

BJT Transistor API

Bipolar-junction-transistor (BJT) circuit maths as an API, computed locally and deterministically. The currents endpoint relates the three terminal currents through the DC current gain β (hFE): the collector current Ic = β·Ib, the emitter current Ie = (β+1)·Ib and the common-base gain α = β/(β+1) ≈ 1, from β and any one current. The bias endpoint analyses the operating point of the classic voltage-divider bias network — from the supply voltage, the two divider resistors, the collector and emitter resistors, β and the base-emitter drop it computes the Thévenin equivalent (Vth = Vcc·R2/(R1+R2), Rth = R1‖R2), the base current Ib = (Vth − Vbe)/(Rth + (β+1)·Re), the collector and emitter currents, the collector-emitter voltage Vce and the node voltages, and classifies the operating region as cutoff, active or saturation. The power endpoint computes the transistor's power dissipation, Pd ≈ Vce·Ic (plus Vbe·Ib), to check it against the rated maximum. Currents are in amperes, resistances in ohms and voltages in volts, with Vbe defaulting to 0.7 V for silicon. Everything is computed locally and deterministically, so it is instant and private. Ideal for electronics, amplifier-design, embedded and hobbyist app developers, biasing and operating-point tools, and electronics education. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is BJT biasing; for op-amp circuits use an op-amp API and for an LED series resistor an LED-resistor API.

Stock Exchanges API

The official ISO 10383 Market Identifier Code (MIC) registry as an API — 2,800+ stock exchanges and trading venues worldwide. Look up a venue by its MIC (e.g. XNAS, XLON), search by name, country, status or market category, and see the operating MIC, legal entity, LEI, city, website and active/expired status. Ideal for fintech, trade reporting, MiFID II compliance and broker tooling.

NAICS API

The North American Industry Classification System (NAICS 2022) as an API — 2,100+ industry codes in a 5-level hierarchy (sector → subsector → industry group → industry → national industry). Look up any code (e.g. 541511 → Custom Computer Programming Services) with its full ancestor chain and direct children; search industries by title (e.g. "software", "restaurant"); or navigate the tree from the 20 top-level sectors down. NAICS is the standard used by US, Canadian and Mexican statistical agencies to classify business establishments. Ideal for business classification, market research, CRM enrichment, lead segmentation and economic analysis.

SEC EDGAR API

US public-company filings and financial statements straight from the U.S. SEC EDGAR system. Search 10,000+ companies (ticker → CIK), list a company's recent filings (10-K, 10-Q, 8-K and more) with document links, pull XBRL financial-statement time series (revenue, assets, net income and any GAAP concept) and run full-text search across all EDGAR filings. Ideal for fintech, fundamental analysis, compliance and research.

Cron API

A fast, fully-local cron-expression toolkit (UTC): validate 5-field cron expressions with ranges, lists, steps, month and weekday names and the common @aliases (@yearly, @monthly, @weekly, @daily, @hourly); compute the next N run times for a schedule from now or any start date; and describe a schedule in plain English. Every endpoint accepts input via the query string or the request body. Pure server-side compute, no third-party upstream, so responses are instant and always available. Ideal for schedulers and job runners, devops and CI tooling, and dashboards that show the next run time of a task.

4,989

Mock Data API

Generate realistic fake data — users, postal addresses, companies and products — for testing, prototyping, demos and database seeding. Localizable to many languages and regions for names, addresses and phone numbers. Server-side and deterministic to call, ideal for CI fixtures and frontend mock states.

QR Code with Logo API

Generate branded QR codes with a centre logo overlay, custom foreground and background colors, chosen size and error-correction level, as PNG or SVG. When a logo is supplied the error-correction level is raised automatically so the code stays scannable, and the logo is placed on a rounded white plate in the centre. Includes one-call helpers that build the correct payload for you: a Wi-Fi-join QR (SSID, password, encryption, hidden), a vCard contact QR (name, phone, email, organisation, title, URL, address) and a batch endpoint that returns up to 100 QR codes in a single request. Supply a logo by public URL, base64 or a raw binary body; receive results as base64 PNG/SVG JSON or, with raw=1, the raw image bytes. Pure server-side rendering (qrcode + sharp), no third-party upstream. Ideal for marketing and packaging, business cards and events, restaurant menus, Wi-Fi sharing and app onboarding.
