Agent Discovery Index

Open discovery layer for machine-accessible services.

Crawls public registries and probes domains for service metadata across multiple discovery formats. Normalises everything into a common schema and exposes a search API for autonomous agents. DNS for agent services — nothing more.

Query the Index

# Search for services by capability
curl "https://agent-index.x402.merkleworks.io/search?capability=llm-accessible"

# Submit a new endpoint for indexing
curl -X POST https://agent-index.x402.merkleworks.io/submit \
  -H "Content-Type: application/json" \
  -d '{"endpoint":"https://my-service.com"}'

# Index statistics
curl https://agent-index.x402.merkleworks.io/stats

Get Discovered

The crawler automatically detects services that publish any of these formats:

/.well-known/agent-card.json /.well-known/agent.json /.well-known/mcp/server-card.json /openapi.json /llms.txt

Or submit your endpoint directly via the API and the crawler will check it on the next pass.
