Pricing

Start free. Move to Starter Access when the hosted API saves real engineering time.

Schema Gateway keeps the evaluation path open: install locally, run the live compiler and regression demos, and only buy when your team wants time-boxed hosted access to one stable signed API surface for compiler, diff, lint, and normalize operations.

Local SDK Free validation, repair, linting, and compilation in your own workflow. Install from a public GitHub release with no npm auth requirement.
Starter Access Signed hosted responses for /v1/compile, /v1/diff, /v1/lint, and /v1/normalize. Best when CI or multiple engineers need the same stable runtime, plus a stateless key claimed from a paid order.

Claim flow

Checkout is not the last step. Claiming the key is.

After purchase, the buyer claims a stateless signed access key directly from the Polar order. That keeps the flow self-serve and machine-friendly.

Use the SDK locally for free.

Evaluate portability, validation, and compilation before paying anything.

Structured Output Reliability Sprint

For teams that want a direct technical pass on portability and regression risk before they rely on self-serve only.

  • audit the current schema and provider workflow
  • identify portability and regression risk
  • configure or recommend a baseline-versus-candidate workflow
  • handoff guidance with Schema Gateway where it fits
Starting at $500

Fixed-scope engineering sprint.

Use this when the team needs judgment, not just hosted endpoints.
