Compare Data and APIs with the tools you already know

Side-by-side pages against popular APIs, with every claim about the other product taken from its own pricing or docs page and linked.

• Sanctions Screening API vs OpenSanctions

  An OpenSanctions alternative built on the official lists, licensed for commercial use

  OpenSanctions is a well-run project and its matching API is good. The catch for a product team is the licence: the data is published under Creative Commons Attribution-NonCommercial, so commercial use needs a separate paid licence, and the hosted API is billed per query. The Sanctions Screening API takes the same official publications the project builds on, OFAC, the UN Security Council, the EU and the UK Sanctions List, loads them into its own database every day, adds a PEP register from Wikidata, and sells screening on a flat token plan with no non-commercial clause.

• IP Intelligence API vs ipinfo.io

  An ipinfo.io alternative with datacenter, cloud and Tor detection on a flat plan

  ipinfo.io is the reference IP data API and its free Lite tier is genuinely unlimited, at country level. Once you need ASN, hosting detection or a risk signal, you move to a per-request plan with overage. The IP Intelligence API answers the question most apps actually ask, is this address a datacenter, a cloud provider, a Tor exit or a residential connection, in one call, with the reasons spelled out, on the same token plan as every other API in the catalog.

• IP Intelligence API vs MaxMind GeoIP2

  A MaxMind GeoIP2 alternative for hosting and Tor signals without per-query billing

  MaxMind is the standard for geolocation databases, and its pay-as-you-go web services are cheap per query. The free GeoLite tier is capped at 1,000 lookups a day per service, carries no support, and its City data is described by MaxMind itself as not recommended for commercial use. The IP Intelligence API covers a different need: routing, hosting and anonymity signals for any address, on the same monthly token plan as the rest of the catalog, with no per-query accounting.

• Barcode Lookup API vs UPCitemdb

  A UPCitemdb alternative with ingredients, allergens and Nutri-Score, not just a product name

  UPCitemdb is a quick way to turn a UPC into a title and some retail listings, and its no-sign-up tier is handy for a prototype. The free plan stops at 100 requests a day and the first paid plan is $99 a month. The Barcode Lookup API is built for food, cosmetics and household products: scan an EAN, UPC or GTIN and get the brand, quantity, ingredients, allergens, Nutri-Score, NOVA group and per-100 g nutrition from 4.3 million products, with the Open Facts attribution included.

• Barcode Lookup API vs Open Food Facts API

  A hosted Open Food Facts API alternative with higher limits and the same open data

  Open Food Facts is where this data comes from, and the project deserves the credit: a community database of food products under the Open Database License. Its public API asks for a custom User-Agent, allows 15 product reads and 10 searches per minute per IP, and points anyone needing more than a few hundred products to the bulk exports. The Barcode Lookup API is that bulk export, loaded into a database built for lookups and search, refreshed daily, served with the attribution the licence requires, and without a per-minute cap.

• Public Holidays API vs Calendarific

  A Calendarific alternative with 204 countries, long weekends and no attribution clause

  Calendarific covers more than 230 countries and its free plan is a fair trial: 500 calls a month with attribution required and limited historical and upcoming data. The Public Holidays API takes a narrower, deeper cut: official public holidays for 204 countries from 2020 to 2028, loaded into its own database, with a few endpoints apps actually need, is today a holiday, what is next, and which weekends are long, on the same token plan as every other API in the catalog.

• Public Holidays API vs Nager.Date

  A Nager.Date alternative with the same holiday data, a key and long weekends

  Nager.Date is the open-source project the Public Holidays API is built on, and its public endpoint is free with no key and, by its own statement, no rate limits. That is a fine choice for a hobby project. Teams that ship products tend to want a database they control, a contract with a vendor, computed answers and a support address. The Public Holidays API keeps the Nager.Date route shapes so switching is a host change, adds is-it-a-holiday, next holidays and long weekends, and serves 2020 to 2028 from its own database.

• Email Validation API vs Hunter.io Email Verifier

  A Hunter.io Email Verifier alternative that checks disposable addresses and costs a token

  Hunter is a prospecting platform first, and its verifier is priced that way: 50 free credits a month, then $49 a month for 2,000 credits, with a verification costing half a credit. Its pricing page also says it does not verify disposable addresses. The Email Validation API is a signup-form tool: syntax, a live MX lookup, a 12,000-domain disposable blocklist and typo suggestions for popular mail domains, at 10 tokens a call on a plan shared with 127 other APIs.

• Email Validation API vs ZeroBounce

  A ZeroBounce alternative for signup-form validation at a fraction of the per-email price

  ZeroBounce is a list-cleaning service with a real API behind it: 100 free validation credits a month, then pay-as-you-go from $39 for 2,000 emails or a $99 monthly subscription. If your job is scrubbing a marketing list before a campaign, that is the right category of tool. If your job is stopping bad addresses at a signup form, the Email Validation API does the checks that matter there, syntax, live MX, disposable domains and typo suggestions, for 10 tokens a call on a plan shared with the rest of the catalog.

• Phone Number Validation API vs numverify

  A numverify alternative for phone validation with commercial use on the free plan

  numverify is the familiar name for phone number validation: 100 free requests a month, with its own table marking the free plan as not for commercial use, then $14.99 a month for 5,000 requests with overage fees past the allowance. The Phone Validation API does the same job from the same kind of source, libphonenumber numbering-plan metadata, as pure computation on our side, so a call costs 1 token and commercial use is included on every plan.

• Tech Stack API vs BuiltWith

  A BuiltWith alternative for live technology lookups without a $295 monthly plan

  BuiltWith is the deepest technology index there is, and its paid plans, from $295 a month, buy historical data, lead lists and relationship graphs that an API of ours does not try to replace. Individual site lookups are free on its website. The Tech Stack API answers the operational question, what is this site running right now, by fetching the page live and matching a curated ruleset of 108 technologies, for 10 tokens a call on the same plan as the rest of the catalog.

• Tech Stack API vs Wappalyzer

  A Wappalyzer alternative with API access from the first dollar

  Wappalyzer's browser extension is how most developers first met technology detection, and its platform now bundles lead lists, email verification and alerts. The free plan gives 50 lookups a month; API access needs a plan, from $250 a month, and the API credits included in plans expire after 60 days. The Tech Stack API is the lookup alone, live against the page, at 10 tokens a call on a plan that starts at $6.99 and covers 127 other APIs.

• Company Enrichment API vs Clearbit

  A Clearbit alternative for company enrichment and logos with published, self-serve pricing

  Clearbit's pricing page now opens with "Clearbit has joined HubSpot", publishes no prices, and its docs sit behind a login. If you only ever wanted the two simple calls, domain to company and domain to logo, the Company Enrichment API and the Logos API do exactly that with a key you can create in a minute: about 125,000 companies from Wikidata joined with SEC EDGAR filer data, and a logo for any domain, on a plan that starts free.
