Rate limit

Public tier is 60 requests per 60 seconds, per IP. Every response carries x-ratelimit-limit, x-ratelimit-remaining, and x-ratelimit-reset (unix seconds). Over the ceiling returns 429 with a retry-after header.

Need higher limits, webhook updates, or a service-level agreement? .

Attribution is the only requirement

Versioning + stability

Additive only within v1. New fields may appear. Existing fields never change type or disappear.
Breaking changes get a new path. /api/v2, not a silent edit to /api/v1.
Deprecation notice. 90 days of double-running before any v1 endpoint is retired.

Paid tier (in planning)

API key auth, 10 kreq/min ceiling, change-diff webhooks, license-change history, and embeddable verification widgets for partner sites. Get in line and we will reach out as it opens.
