## 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 providersignal-medicaid-dentist-directory-198c1dba
```

Example prompt: Can you find me Medicaid dentists in Houston, TX who are accepting new patients and speak Spanish — show me up to 50 results?

## When to prefer this

Use this endpoint when you need to locate Medicaid-enrolled dental providers in any US state with optional filtering by geography (city, ZIP), clinical specialty (e.g., Pediatric, Orthodontics), patient-acceptance status, language, or special-needs accommodation. It is the right choice when you need source-cited, NPI-matched provider data drawn from official state Medicaid submissions and federal datasets. Prefer this over general provider directories when Medicaid enrollment and plan participation details are specifically required.

## Known failure modes

- Missing required 'state' query parameter returns a validation error
- Invalid state code (not a 2-letter uppercase code) returns a pattern validation error
- Unsupported or misspelled specialty/city/language values silently narrow results to zero (missing data in source, not an API error)
- 'accepting' or 'special_needs' flags may return fewer results than expected because many states never populate these fields
- Payment failure (402) if x402 USDC payment or MPP Stripe token is invalid or insufficient
- Rate limiting or auth failure if Bearer token subscription is expired or missing
- ZIP code not matching 5-digit pattern returns a validation error

## How this service works

Healthcare market intelligence API. Unified provider directory + acquisition signals + license-events feed across all 50 US states, derived from NPI + state dental boards + CMS Medicare + OIG LEIE + state Medicaid + HRSA HPSA designations. All responses ship a citation envelope (`meta.envelope_version`, `meta.source_attribution`, `meta.request`) so agents can verify source freshness without out-of-band validation. Paid `/api/v1/agent/*` endpoints accept two per-call rails on a single 402: x402 (USDC on Base mainnet) and MPP (Stripe card via a Shared Payment Token), plus Bearer-token subscription auth for existing API keys. See [/docs/agent-payments](/docs/agent-payments) for the full flow. See [/docs/fields](/docs/fields) for the field glossary and [/llms.txt](/llms.txt) for the LLM crawler index.

## Output

A JSON object containing a paginated list of Medicaid-enrolled dental provider locations for the requested state and filters. Each provider record includes name, NPI, address, city, ZIP, county, phone, specialty, Medicaid plan participation, languages spoken, accepting-new-patients flag, special-needs accommodation flag, and the date the listing was last updated. The response also includes a meta citation envelope (envelope version, source attribution, request details), a disclaimer about state-listed vs verified acceptance, the total number of matching rows, and the number of provider locations returned.
