Paths & Operations 8

Across 8 paths, the API surfaces 8 operations — 8 GET. Each is listed below with its method, path, parameters, and response codes.

blocks 8
GET
/blocks

Schemas 24

The contract defines 24 schemas that model the data the API accepts and returns. The most detailed are Block (14 properties), Extrinsic (11 properties), BlockRaw (9 properties), BlockHeader (8 properties). Each schema is shown below with its type and property counts.

Where this information came from

This is an independent, third-party profile of Kusama blocks API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
