Observe and detect
Know when a provider changes before your customers do
Instrument the integrations you already run. Seamward records redacted structural evidence after execution and compares it with the contract and the outcome your team expects.

What it detects
- Renamed, removed, and retyped fields
- A value that keeps its type and changes its meaning: units, formats, blanks
- Auth and status shifts
- A connection that goes quiet, or drops far below its usual volume
- Event reordering and late deliveries
- Successful responses whose expected business outcome never appeared
- Announced changes before they land: deprecation and sunset dates from response headers, and changes in a published OpenAPI document you ask it to watch
- Expiry and quota warnings: a rate limit running low or changing, webhook signatures starting to fail, and credential dates your team records
How it stays safe
- Runs outside the request path
- Fails open when Seamward is unavailable
- Redacts and hashes before transmission
- Stores structural evidence, never raw payloads by default
