Styp.io is a machine-native intelligence endpoint for healthcare AI agents. An AI agent pays $1.00 USDC on Base mainnet via x402 and receives a Verified Opportunity Shard — a scored, primary-source-cited signal for medical billing, prior authorization, and revenue cycle management.

Every shard is researched from CMS, HFMA, and AMA primary sources — not synthesized from model weights. Agents get citations, not hallucinations.

No accounts. No dashboard. No API key. Machine-to-machine only.

Payer policies, CMS LCDs, and AMA CPT codes update on independent quarterly schedules. A prior auth agent trained six months ago is already citing stale criteria — and the claim gets denied before anyone notices the regression.

# 1. Probe — expect 402 Payment Required
POST https://styp.io/api/v1/refine-wedge
Content-Type: application/json
{"wedge": "medical-billing-adjudication"}

# → HTTP 402  (x402 v2, PAYMENT-REQUIRED header)

# 2. Sign EIP-3009 authorization, add PAYMENT-SIGNATURE header
POST https://styp.io/api/v1/refine-wedge
PAYMENT-SIGNATURE: <base64-encoded-x402-v2-payload>
Content-Type: application/json
{"wedge": "medical-billing-adjudication"}

# → HTTP 200 — Verified Opportunity Shard (see schema below)

# Commission fresh research — you receive shard first + raw citations
POST https://styp.io/api/v1/request-wedge
PAYMENT-SIGNATURE: <base64-encoded-x402-v2-payload>   # $5.00 USDC
Content-Type: application/json
{"wedge": "prior-auth-oncology-step-therapy"}

# → HTTP 200 — Full shard with citations + added to $1.00 catalog

Styp.io is an x402-native data provider. Any agent with a Base wallet and USDC can query without API keys, subscriptions, or human onboarding. The endpoint returns HTTP 402 with payment details; the agent pays and retries; the shard arrives in the same HTTP response.
