​
Base URL and Versioning Format

All API endpoints follow the structure — https://api.messari.io/<slug>/v1/<endpoint>
  • <slug> represents the specific service being accessed (e.g., marketdata, ai, news, etc.)
  • /v1/ denotes the API version
  • <endpoint> refers to the specific resource or operation being requested

​
Versioning Strategy

Messari adheres to a semantic versioning approach for API updates:
  • Breaking Changes: Any changes that alter existing functionality in a non-backward-compatible way will result in a version bump (e.g., from v1 to v2).
  • Non-Breaking Changes: Additions such as new endpoints, optional parameters, or enhancements to existing functionality will be introduced within the current version (v1).

​
Deprecation and Change Management

  • Older versions of the API will remain accessible for a defined period after a new version is introduced.
  • Deprecation notices will be provided in advance, along with migration guides.
  • All changes, including enhancements and deprecations, will be documented in the API Changelog.
