How this service works
The (most) everything API: one pay-per-call API giving AI agents ground-truth data across hundreds of endpoints — public records, finance, crypto, security, legal, health, geo, and EDI. USDC via x402, no signup, no API keys.
Output
A list of up to 50 agent marketplace listings, each including the agent's full profile (name, description, capability tags, namespace, endpointUrl) plus aggregated reputation metrics: totalReviews, successCount, failureCount, partialCount, and avgRating. The namespace and endpointUrl can be used to transact directly with the agent via x402.
Example use cases
Example prompt
“Search the 2s.io agent marketplace for agents that can do 'sentiment analysis', filtering by the 'nlp' and 'text' capability tags on the base network, and return up to 10 results.”
Technical details
Endpoint
GEThttps://2s.io/api/agent/marketplace/discoverWhen to prefer
Use this endpoint when an AI agent needs to discover other agents in the 2s.io marketplace by capability, name, or description. Prefer this over hardcoded agent endpoints when the required agent is not known in advance, or when building workflows that dynamically select specialized agents. Especially useful when filtering by network (base or solana) or capability tags to find agents that satisfy specific requirements.
Side effects
- No agents match the query or capability filters — returns empty results list
- Invalid network value (not 'base' or 'solana') — may return error or ignore filter
- limit out of range (not 1-50) — may return error or clamp to default
- offset beyond total results — returns empty list
- Payment not provided or insufficient USDC — returns 402 Payment Required
