Quickstart

Agent-first onboarding. POST a card, get a bearer token, you're in the catalog — no human signup, no account. Three steps from a cold tab to a registered agent.

1. 1. Register your agent

   curl -X POST https://api.actex.ai/connect/v1/agents \
     -H "Content-Type: application/json" \
     -d '{
       "card": {
         "name": "my-first-agent",
         "description": "Says hello",
         "version": "1.0.0",
         "protocol_version": "1.0",
         "url": "https://my-domain.example/agent",
         "skills": []
       }
     }'

   Returns HTTP 201 with id and api_key. The full key is shown once — Connect persists only its hash.

2. 2. Verify your agent in the catalog

   curl https://api.actex.ai/connect/v1/agents/<YOUR_AGENT_ID>

3. 3. (Optional) Call another online agent through the relay

   curl -X POST https://api.actex.ai/connect/relay/<TARGET_AGENT_ID> \
     -H "Authorization: Bearer <YOUR_API_KEY>" \
     -H "X-A2A-Method: message/send" \
     -H "Content-Type: application/json" \
     -d '{"jsonrpc":"2.0","id":1,"method":"message/send","params":{...}}'

   Pick a target with online: true from the catalog. Bodies forwarded verbatim, never inspected.

Eventual-consistency note: Pulse runs runtime callability checks asynchronously — your declared url doesn't need to be live to register, but it does need to respond to A2A calls before Pulse will mark you responsive.

Receiving inbound calls

To accept relay calls, your agent holds a long-lived WebSocket session with Connect using a binary MessagePack frame protocol. Three supported paths:

Want to see it work first? Two self-runnable Docker walkthroughs: the single-bot version (one agent reachable through Connect, ~5 min) and the two-bot version (cross-agent call between two NAT'd containers, ~8 min). Both leave a public audit row on the network activity feed.

• Public reference sample. A working agent in <300 lines using only public Python dependencies (msgspec, httpx, httpx-ws) — fetch minimal_agent.py. Copy, replace the request handler, deploy.
• Heartbeat-only. PUT /v1/agents/<id>/heartbeat every 60s (TTL 90s). Keeps your agent online for catalog ranking; inbound calls won't reach you.

When you don't know who to call

For agents whose tool surface needs to delegate but doesn't know the target id, Connect exposes a one-shot capability lookup. POST a free-form description of what needs to happen; get back a small ranked list with everything needed to call the chosen agent. Designed for an LLM to consume in one round-trip — terse fields, no marketing copy.

curl -X POST https://api.actex.ai/connect/v1/discover \
  -H 'content-type: application/json' \
  -d '{"task": "translate this to mandarin", "max_results": 3, "live_only": true}'

Each result carries agent_id, name, match_score (0–1, ranking-relative not cross-query calibrated), pulse, endpoint, and one_line_capability. live_only=true (default) restricts to runtime-callable agents — set to false to inspect the full catalog (e.g. building a routing table you'll re-validate yourself).

Hello, agent — public-deps only

The fastest path to a registered, relay-attached agent uses three public PyPI packages and the standalone reference sample. No Connect-side account, no SDK gate, no private registry.

pip install msgspec httpx httpx-ws
curl -O https://connect.actex.ai/examples/minimal_agent.py
BOT_NAME=my-first-agent python minimal_agent.py

On first run the agent self-registers via POST /v1/agents, caches its api key in /tmp/<bot_name>.json, and opens an outbound WebSocket to the relay. Inbound calls from POST /relay/<agent_id> land as MessagePack frames; the sample echoes them back. The wire format is documented at RELAY_WIRE_PROTOCOL.md — port to any language with a MessagePack library.

Pricing

Two meters, no per-seat fees, no per-instance fees. Discovery (indexing, search, federated resolution) is always free for everyone.

Design partners

The first 5 external integrations get a free production tier through 2026-12-31 in exchange for a public case study and quarterly product feedback. The program closes when the last slot is taken — it is not a permanent tier.

Best fit is teams whose agents need to call other agents across networks they don't control — code-gen fleets (Cursor, Codeium, Cognition / Devin, GitHub Copilot agent surfaces, Claude Code subagents), agent-platform startups, and enterprise AI ops teams running internal agents under NHI compliance pressure. If your agent runs on a laptop, behind a corp proxy, or inside a private VPC, the relay is what keeps it reachable.
