Documentation

Understand fit fast, run a live request, then go deeper only when you need detail.

This page is written as an answer-first reference for operators, developers, search systems, and AI assistants evaluating whether opendata is the right public-data API layer for a job.

Quick answers

What it is

A packaged public-data API catalog for compliance screening, entity verification, procurement intelligence, and recurring monitoring workflows.

Best fit

Teams that need repeatable API search, export, and productized public-data workflows rather than manual portal browsing.

Not a fit

One-off casual lookups, private proprietary datasets not in the catalog, or legal/compliance advice rather than data retrieval.

Fastest evaluation path

Open a solution page, run the prefilled Playground request, inspect the matching product, then check the raw catalog entry if you need schema-level detail.

Quick start

Use one evaluation key, run one real request, and only then decide whether this belongs in recurring work.

curl -H "X-API-Key: pk_live_..." \
  "https://opendata.best/api/v1/data/products/uk_charity_commission_register/search?q=Acme&limit=5"

1. Get a key

Create an account and keep one evaluation key on the current device.

2. Run a real request

Use Playground or cURL first. Don't start by reading every source page.

3. Inspect detail only if needed

Product pages explain the packaged workflow; catalog pages expose schema and raw source details.

Best fit and limits

Best fit

  • Supplier screening and sourcing operations
  • KYB and due diligence workflows
  • Government opportunity intelligence
  • Regulatory monitoring and briefing workflows
  • Builders packaging public-data APIs into their own tools

Known limits

  • Coverage is limited to datasets and modules that exist in the catalog
  • Freshness differs by source and should be checked on each product or catalog page
  • Paid plans expand quota and export, but do not turn public data into legal advice
  • Private or closed commercial data sources are out of scope unless explicitly added

Freshness and data expectations

There is no single refresh promise across the whole site. Each raw product inherits its own source cadence. Use the raw catalog when freshness matters to the workflow.

Packaged products

Best for understanding the workflow, target user, outputs, and repeatable query path.

Raw catalog pages

Best for checking source mode, field names, schema shape, refresh labels, and lower-level query behavior.

Plans and quotas

Best for evaluating whether free testing is enough or whether recurring export and higher quotas are required.

Workflow guides

Use these when the question is not “what is the API?” but “how do I apply it to a real operating task?”

Scenario guides

Start here if the main question is “what job can this solve for me?” instead of “what endpoint do I call first?”

Bid Opportunity Intelligence

Find new bids, understand buyer history, and export contract intelligence fast.

Identity & KYB

Legal entity identity, registration, ownership, licensing, and existence checks.

Risk & Restrictions

Sanctions, regulated entities, enforcement actions, and restricted-party screening.

Procurement Intelligence

Opportunities, awards, buyers, incumbents, and contract histories.

Healthcare Regulatory

Drugs, devices, providers, facilities, trials, recalls, and safety signals.

Construction & Geospatial

Permits, parcels, zoning, property, hazards, contractors, and project geography.

Legal & Regulatory Change

Laws, regulations, notices, decisions, and update tracking across official sources.

Authentication and plans

All public API reads use the X-API-Key header. Paid plans expand the same key to support more quota, export, and recurring usage. Current self-serve plans loaded on this instance: Business, Free, Pro, Starter.

Machine-readable entry points

These are the best starting points for AI assistants, agentic systems, and search-oriented retrieval flows that need a concise canonical map of the public site.

Concise map

Use /llms.txt for the compact public overview, major entry points, featured solutions, products, API surface, and crawler guidance.

Full reference

Use /llms-full.txt for the expanded machine-readable reference covering solutions, packaged products, raw catalog entries, modules, plans, compare pages, and free tools.
