Why does each state accept different search fields?

Every state bar publishes its directory with its own search form. Each state is an adapter that declares the criteria it supports, so ask the state endpoint which fields are valid before searching.

Yes. Each search queries the state bar's directory at request time, so status reflects what the bar publishes right now rather than a cached copy.

What fields come back?

Name, bar number, status, admission date and the location and contact details the state discloses. Fields vary by state and are documented per adapter.

What does a call cost?

10 tokens per search, because each one performs a live query against the bar directory. Listing states and their criteria is cheaper.

US Lawyers API

Search 14 state bar directories through one API: verify an attorney's licence, status and admission

Look up US attorneys by jurisdiction through one normalized API. Every state bar publishes its directory with a different search form, so each state is an adapter that declares its own search criteria: list the active states and the fields each one supports, then run a validated search to retrieve the matching attorney records. Fourteen jurisdictions are live — California, Texas, Georgia, Colorado, Oregon, Maryland, Delaware, Arizona, Louisiana, Maine, Tennessee, Montana, Utah, and North Carolina — returning fields such as license status, admission date, firm/address, phone, and (where published) email and practice areas, sourced directly from each official bar directory. More states are being added.

Every call needs an X-Api-Key header. A free key includes 500 tokens a month, no card required. 10 tokens per call, so the free plan covers about 50 calls a month.
