health.provider-profile

Provider 360 — everything we know about a US healthcare provider, merged on their 10-digit NPI in one call. Combines three federal datasets: identity (NPPES registry: name, specialty/taxonomy, practice address, licenses), industry payments (CMS Open Payments: what drug & device makers paid them), and Medicare billing (CMS Physician & Other Practitioners: services, charges, and Medicare payment amounts). Each section reports found/error independently — a provider with no Open Payments or Medicare record still returns identity. KYC, healthcare-fraud research, investigative journalism, provider due diligence. Pass npi (required). For the individual sources see /api/license/medical, /api/health/open-payments, /api/health/medicare-provider.

Overview

The provider profile API is a pay-per-call health endpoint built for AI agents and autonomous software. Provider 360 — everything we know about a US healthcare provider, merged on their 10-digit NPI in one call.

There is no signup and no API key. An agent (or any HTTP client) hits the endpoint, receives an x402 "402 Payment Required" challenge, signs a sub-cent USDC payment on Base or Solana, and retries — the data comes back on the paid request. That makes it a drop-in provider profile data source for an agent tool-use loop, an MCP host, or a backend that needs health data on demand without onboarding to yet another vendor portal.

Use cases

• Give an AI agent live provider profile lookups as a tool, with no API key to provision or rotate — the agent pays per call from a wallet you fund.
• Enrich records in a data pipeline with health data, paying only for the calls you actually make instead of a monthly seat.
• Ground LLM answers in authoritative health data to cut hallucination, then optionally request a signed response for verifiability.
• Prototype against the live provider profile API in minutes using the free trial call, then flip to per-call x402 payment for production with no code change.

Parameters

Code samples

# 1. Probe with no auth → 402 envelope with PaymentRequirements
curl -sS 'https://2s.io/api/health/provider-profile?npi=12345'

# 2. Sign + retry with PAYMENT-SIGNATURE:
curl -sS 'https://2s.io/api/health/provider-profile?npi=12345' \
  -H 'PAYMENT-SIGNATURE: <base64-json-payload>'

# Or use the canonical runner (handles probe → sign → retry):
#   EVM_PRIVATE_KEY=0x... node --env-file=.env.local \
#     --experimental-strip-types scripts/x402-pay.ts \
#     'https://2s.io/api/health/provider-profile?npi=12345'

import { TwoS } from '@2sio/sdk'

const client = new TwoS({
  privateKey: process.env.EVM_PRIVATE_KEY as `0x${string}`,
})

const result = await client.health.providerProfile({
  "npi": "12345"
})

console.log('endpoint:', result.endpoint)
console.log('cost:', result.costUsd, 'USDC')
console.log('tx:', result.settlement?.txHash)
console.log('data:', result.data)

import os
from twosio import TwoS

client = TwoS(private_key=os.environ["EVM_PRIVATE_KEY"])

result = client.health.provider_profile(npi="12345")

print("endpoint:", result.endpoint)
print("cost:", result.cost_usd, "USDC")
print("tx:", (result.settlement or {}).get("tx_hash"))
print("data:", result.data)

// 1. Add @2sio/mcp to your MCP host config (Claude Desktop example below).
//    EVM_PRIVATE_KEY funds x402 payments per call.

// 2. Once the server is running, agents call this tool via standard MCP:

FAQ

Do I need an API key to use the provider profile API?

No. health.provider-profile is x402-native — there is no signup and no API key. Your client makes the call, receives a 402 with payment requirements, signs a USDC payment, and retries. Funds come from a wallet you control.

How much does the provider profile API cost?

$0.00576 USDC per call, charged per request. There are no monthly fees, seats, or minimums — you pay only for the calls you make.

Can I try the provider profile API for free first?

Yes. Add ?trial=1 (or the header X-2s-Trial: 1) to get a free real call per endpoint per hour, so you can verify the response shape before wiring payment.

Which networks and tokens are supported?

USDC on Base (via EIP-3009 transferWithAuthorization) or Solana (SPL transfer), using the open x402 payment protocol.

How do I call health.provider-profile from an AI agent or MCP host?

Use @2sio/sdk (TypeScript), 2sio (Python), or the @2sio/mcp server for any MCP host — each handles the probe → sign → retry loop for you. See the code samples on this page.
