# NCARB Certified Architects Directory

> NCARB Certified Architects Directory is a paid API for AI agents from api.companyrecords-api.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-24).

Searches NCARB's official Certificate Lookup to find US national certificate holders (NCARB-certified architects) by name, city, state, or country.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability ncarb-certified-architects-directory-15142f37
```

Example prompt: Can you look up NCARB-certified architects with the last name 'Martinez' in Texas? Show me up to 20 results.

## When to prefer this

Use this endpoint when you need to verify or discover architects who hold the NCARB national certificate, especially for cross-state practice verification or interstate project staffing. It is sourced directly from NCARB's official Certificate Lookup, making it authoritative for national certificate holders. Prefer this over state board rosters when checking national certification status across multiple jurisdictions; use state board rosters to confirm a specific state license number.

## Known failure modes

- No results returned when name spelling doesn't match NCARB records exactly
- Partial name matches may return too many or too few results if filters are too broad or narrow
- Invalid state code (non-standard abbreviation) may return empty results
- Country code must be ISO3 format — ISO2 codes like 'CA' will not work for country filter
- Pagination with large offsets may return empty arrays if offset exceeds total
- Rate limit or payment failure may result in 402 response requiring USDC payment

## How this service works

Pay-per-call company registry, government, legal and B2B data tools for AI agents, from official registers and public sources. Payment: x402, USDC on Base, Solana, Arc, Polygon, Arbitrum, Monad, World Chain, Optimism, Avalanche, Celo or Stellar, or RLUSD/XRP on the XRP Ledger. No signup, no API key; a failed call is not charged.

## Output

Returns a JSON object with the total count of matching architects, pagination details (offset, hasMore), the source NCARB API URL, a timestamp of when data was checked, and an array of architect records each containing a unique certificate ID, first name, last name, city, state, and country.
