Vertical templates

Vertical templates are domain-specific generation modes that add industry-standard patterns to your wrapper automatically — without you having to describe them.

When you select a vertical on the Generate page, StateAnchor applies a set of domain-specific rules to the generation. For example, the FinTech vertical automatically uses string amounts instead of floats, adds idempotency key helpers, and follows PCI-DSS logging guidelines — even if you didn't mention any of that in your description.

Verticals are especially useful when working with regulated industries where getting the patterns wrong has real consequences.

💳 FinTech

Financial APIs — payments, banking, crypto, lending

What this vertical adds

  • Decimal precision handling (uses string amounts, never floats)
  • Idempotency key helpers on mutation endpoints
  • Retry logic with exponential backoff for transient errors
  • PCI-DSS aware: no plaintext card data in logs or error messages
  • Audit-ready error codes matched to HTTP status
  • Webhook signature verification helper

Works well with

Stripe, Plaid, Brex, Coinbase, Dwolla

🏥 HealthTech

Healthcare and clinical APIs — EHR, FHIR, telehealth

What this vertical adds

  • PHI data minimization: no patient data in error messages or logs
  • HIPAA-safe logging patterns with field redaction
  • SMART on FHIR OAuth2 auth flow helpers
  • FHIR R4 resource type support
  • Pagination helpers for large clinical datasets
  • Rate limit handling for high-availability clinical systems

Works well with

Epic, Athenahealth, Health Gorilla, Veradigm

🛒 eCommerce

Commerce APIs — orders, inventory, fulfillment

What this vertical adds

  • Webhook signature verification (HMAC-SHA256)
  • Cart and order state machine helpers

🔧 DevTools

Developer tooling APIs — project management, CI/CD, observability

What this vertical adds

  • Cursor and link-header pagination helpers
  • OAuth2 refresh token handling with automatic renewal
  • GraphQL query builder helpers (where applicable)
  • Webhook event type-safe handlers
  • Batch operation helpers
  • Rate limit headers parsed and exposed

GitHub, Linear, Jira, PagerDuty, Datadog

When to use a vertical vs. General mode

Use General mode when your API doesn't fit a vertical, or when you want the simplest possible wrapper without domain-specific patterns.

Use a vertical when:

  • You're working in a regulated industry (finance, healthcare)
  • You know the API you're wrapping fits the domain
  • You want best-practice patterns without describing them yourself
  • Your team has compliance or audit requirements
