# ProviderSignal Medicaid Rates API

> ProviderSignal Medicaid Rates API is a paid API for AI agents from providersignal.com, paid per call via x402, $0.5/call, status unknown (last checked 2026-09-16).

Returns published Medicaid fee-for-service reimbursement rates for dental procedures by US state, including basket index and national ranking.

## Facts

- Endpoint: GET https://providersignal.com/api/v1/agent/medicaid/rates
- Price: $0.5/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-16

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 providersignal-medicaid-rates-api-0b6748f2
```

Example prompt: What does Medicaid pay for a D2391 composite filling in Texas, and how does Texas rank nationally for Medicaid dental reimbursement rates?

## When to prefer this

Use this endpoint when you need authoritative, source-cited Medicaid dental reimbursement rates for a specific US state, especially when you need CDT-code-level granularity, national ranking context, or a basket index for benchmarking. Prefer this over general healthcare data APIs when the use case is specifically dental Medicaid fee schedules with verifiable source attribution and freshness metadata.

## Known failure modes

- Missing required 'state' query parameter returns a validation error
- Invalid state code (not a 2-letter uppercase code) returns a pattern mismatch error
- Invalid CDT code format (not matching ^D\d{4}$) returns a validation error
- State with no published Medicaid fee schedule may return null rates or empty basket
- Payment failure via x402 or MPP returns HTTP 402 with payment instructions
- Rate limiting or quota exhaustion returns a 429 or billing 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

Returns a JSON object with the state's Medicaid fee-for-service dental rates including: an array of procedure codes with rates and descriptions, a basket index score, national ranking among all 50 states plus DC, total number of codes covered, effective year, and a disclaimer. Also includes a meta citation envelope with source attribution and request billing details.
