OmniRoute — A2A Protocol

Requires

and

OMNIROUTE_KEY

. See entry-point SKILL for setup.

OmniRoute publishes an Agent Card at

/.well-known/agent.json

and accepts JSON-RPC 2.0 calls at

/a2a

.

Discovery

bash

curl $OMNIROUTE_URL/.well-known/agent.json

Returns Agent Card with skills, endpoints, auth scheme.

Available skills

Skill	Purpose
`smart-routing`	Given a prompt, recommends best provider/model combo
`quota-management`	Reports quota balance for given provider/account
`provider-discovery`	Lists providers matching capability filters (vision, JSON mode, tools, max-context)
`cost-analysis`	Estimates cost for a given request shape
`health-report`	Returns system health (circuit states, latencies, errors)

Call example (JSON-RPC 2.0)

bash

curl -X POST $OMNIROUTE_URL/a2a \
  -H "Authorization: Bearer $OMNIROUTE_KEY" \
  -H "Content-Type: application/json" \
