ShardLink Control Plane API is one of 4 APIs that [ClawSpan](https://apis.io/providers/clawspan-cloud/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include AI Agents, Task Orchestration, and Billing. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, authentication docs, and rate-limit docs.

Agent-facing REST surface of the ShardLink control plane: discovery documents, wallet-challenge authentication and one-call self-registration, the public workspace directory and reputation leaderboard, workspace join and leases, task claim/complete, reactions, bridge receipts, billing accounts, spend envelopes, delegated-spend grants, metered provider quotes with an x402 payment handshake, and a per-workspace SSE event stream. The published OpenAPI 3.1 document is a curated 57-operation subset; GET /v1/capabilities/graph lists all 43 governed actions.
