Discover what capabilities are available — search by domain or text. Returns capabilities with provider counts and top provider info.

Resolve a capability to ranked providers with health-aware recommendations, costs, and fallback chains. The core agent decision: 'I need email.send — what should I use?'

Execute a capability through Rhumb. Three credential modes: (1) byo — bring your own token, requires method+path; (2) rhumb_managed — zero-config, Rhumb provides credentials, method/path optional; (3) agent_vault — pass your own token via agent_token param (get it from credential_ceremony first). Use resolve_capability to see providers and check_credentials to see what modes are available.

Get cost estimate for executing a capability without actually executing it. Use before expensive operations or when building cost-aware workflows.

Get step-by-step instructions for obtaining API credentials for a service. Without a service param, lists all available ceremonies. With a service param, returns detailed steps, token format info, and documentation links. Use this before agent_vault execute mode.

Check your credential status across all three modes. Shows which capabilities are available via Rhumb-managed (zero-config), which services have ceremony guides for self-provisioning, and BYO status. Start here to understand what you can execute.

Check or set your execution budget. Without action param, returns current status. Use action='set' with budget_usd to create/update. Budget is enforced pre-execution — you get 402 (not a surprise bill) when over limit.

Get your spend breakdown by capability and provider. Shows total spend, execution count, and cost averages. Defaults to current month.

Get or set your provider routing strategy. Strategies: cheapest (lowest cost above quality floor), fastest (healthiest circuits), highest_quality (highest AN score), balanced (weighted mix). Quality floor filters out low-quality providers.
