API marketplace · EU · GDPR-ready

Ship APIs without leaking your secrets.

oanor is a marketplace gateway for your APIs. Customers call your endpoints through us — and your upstream URL, keys and tokens never reach the browser.

leaks

Zero secret leak — verified in CI

Gateway responses are checked so upstream URLs, auth headers and provider tokens stay out of client traffic.

EU-hosted, GDPR-aligned

Built for EU infrastructure, audit logs, consent-aware flows and metadata-only usage logging.

Multilingual landings, auto-translated

i18n

Publish once, ship localized API pages and SEO metadata without slowing provider onboarding.

Per-key usage, quotas, /metrics

/metrics

Developers and providers get scoped keys, quota signals and Prometheus-ready platform metrics.

Features

Everything an API marketplace needs.

From a clean gateway to per-customer keys, quotas and a SEO-ready public landing per API.

Issue, revoke, rotate. Plaintext shown once. SHA-256 stored. RPS quota enforced atomically.

Plans & quotas

Provider-defined tiers — free, paid, trial, pay-as-you-go. RPS + monthly + daily quotas enforced in Redis.

Multilingual auto-content

Hero image, SEO copy, translations generated on publish. EN + DE today, ten more on the way.

Built-in observability

Prometheus /metrics endpoint, Redis stream of every call, Postgres audit log of every admin action.

Pure PHP, no framework

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.

Genome Assemblies API

Reference genome assemblies as an API — powered by NCBI Assembly, the registry of genome builds for organisms across the tree of life. Search assemblies by organism (or free text) and look up any assembly's metadata: its accession (GCF_… RefSeq or GCA_… GenBank), name (e.g. GRCh38.p14), organism and taxon id, assembly level (complete genome, chromosome, scaffold or contig), contiguity statistics (contig and scaffold N50), sequencing coverage, RefSeq category, UCSC and Ensembl names, the submitting organization, release date and FTP download paths. From the human reference genome to any sequenced microbe, plant or animal, it turns the genome-assembly registry into a clean search-and-fetch API. A genome-assembly registry — distinct from sequence (ENA), genome annotation (Ensembl), variant (ClinVar, dbVar) and gene-expression (GEO) databases. Open data from NCBI Assembly (public domain).

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.

European Parliament API

The European Parliament as an API, powered by the official European Parliament Open Data portal (data.europarl.europa.eu). Track the EU's directly-elected legislature: list the Members of the European Parliament (MEPs) for any parliamentary term — term 10 is the current 2024-2029 Parliament — with pagination; read an individual MEP's profile including their full name, country of representation, gender, contact email, official photo and place of birth, together with their committee, political-group and delegation memberships split into current and past, each with the role held (member, chair, vice-chair, …) and start/end dates; and browse the Parliament's corporate bodies — its standing and special committees (such as ECON, ENVI, LIBE), political groups and inter-parliamentary delegations — with their id, acronym, label and type. The organization id that appears in an MEP's memberships matches a corporate body, so you can resolve exactly which committee or group a member sits on. Ideal for civic-tech and transparency tools, political research and journalism, lobbying and public-affairs monitoring, and EU-policy analytics. MEP ids come from the MEPs endpoint. Data from the European Parliament (CC-BY 4.0).

Quick answers about pricing, quotas, and integration.

What is oanor?

oanor is a privacy-first API marketplace built in the EU. We host and proxy third-party APIs through our no-leak gateway so you can integrate them without ever exposing your upstream secret.

How do I get started?

Sign up for free, generate an API key in your developer dashboard, and call any listed API with the x-oanor-key header. The free tier gives you 100 calls per month — no credit card needed.

Is oanor free?

Yes — every API on the marketplace has a free tier with 100 calls per month. Paid tiers start at €15/month for higher quotas and faster rate limits.

Is oanor GDPR-compliant?

Yes. We're EU-based, host all data in the EU, and never share your personal data with the upstream providers. Your API key never leaves our gateway.

Which APIs are available on oanor?
