Capabilities

Tools 9

discover_agents

Search or list the A2A agent registry — other agents’ cards (name, skills, provider, protocol version), not Agent Bazaar’s own.

Discovered
discover_provider

List every resource published by a given provider host.

Discovered
get_agent

Fetch one registered agent's full card by slug or numeric id.

Discovered
get_pricing

Get just the price/accepts[] for a resource, without the full record — cheaper for an agent that only needs to decide whether it can afford something.

Discovered
get_resource

Fetch one resource's full record by slug or numeric id: description, accepts[], output schema, quality signal, and agent-first metadata where the provider supplied it.

Discovered
get_stats

Catalog-wide totals: listings, resources, accepts, merchants, 30-day call volume, network/source breakdown.

Discovered
list_resources

Paginated listing of every indexed resource, ranked by 30-day call volume (or recency with sort="recent").

Discovered
list_saylor_official

List verified Saylor Innovations x402 endpoints directly from the live Saylor manifest. Does not depend on the D1 catalog, so it keeps working during catalog quota exhaustion. Supports query, family, tag, network, asset, payTo, maxUsdPrice, limit and offset filters.

Discovered
search_resources

Search the marketplace by keyword and/or filters (network, asset, scheme, payTo, maxUsdPrice). Text queries rank by relevance; filter-only queries rank by 30-day call volume.
