Autonomous AI agents need infrastructure that works without human supervision. That means webhook endpoints that don't expire, don't require account creation, and are accessible via clean APIs. HookRelay was designed for exactly this.
An AI agent deploys a landing page and uses webhook.site as the form backend. Everything works. Seven days later — while the agent is focused on other tasks — the webhook expires. The form on the landing page continues to look like it's working. But every submission silently fails. The agent discovers this on the next cycle when it checks for signups and gets zero. Days of potential signups: gone.
This is a real failure mode that autonomous agents face. The problem isn't the agent's logic — it's that the infrastructure it relied on was designed for temporary human use, not autonomous machine use.
Autonomous AI agents have different infrastructure requirements than human developers:
No account. No expiry. No configuration. POST to your endpoint, GET your submissions. Works from any static site. Readable via API. Deployable in a curl command.
When an agent deploys a landing page to test a business idea, it needs somewhere to collect signups. HookRelay acts as the form backend — no server setup required.
<!-- In the agent's landing page HTML -->
<form id="waitlist-form">
<input type="email" name="email" placeholder="your@email.com" />
<button type="submit">Join Waitlist</button>
</form>
<script>
document.getElementById('waitlist-form').addEventListener('submit', async (e) => {
e.preventDefault();
const email = e.target.email.value;
await fetch('https://hookrelay-app.netlify.app/api/webhook/my-project-waitlist', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({ email, ts: new Date().toISOString() })
});
// Show success state
});
</script>
Every cycle, the agent checks for new signups by GETting the submissions endpoint. No login, no UI — just an API call.
# In the agent's cycle script
SIGNUPS=$(curl -s https://hookrelay-app.netlify.app/api/webhook/my-project-waitlist/requests)
COUNT=$(echo $SIGNUPS | python3 -c "import sys,json; print(json.load(sys.stdin)['total'])")
echo "Current signups: $COUNT"
# Or in Python
import requests
r = requests.get("https://hookrelay-app.netlify.app/api/webhook/my-project-waitlist/requests")
data = r.json()
signups = [item['content']['email'] for item in data['data']]
print(f"Got {data['total']} signups: {signups}")
Multiple agent instances or different agents in a pipeline can communicate via shared webhook endpoints. One agent POSTs events, another polls for new events on its cycle.
# Agent A: publish an event
curl -X POST https://hookrelay-app.netlify.app/api/webhook/agent-pipeline-events \
-H "Content-Type: application/json" \
-d '{"event": "validation_complete", "idea": "hookrelay", "score": 8.5}'
# Agent B: poll for events on its next cycle
curl https://hookrelay-app.netlify.app/api/webhook/agent-pipeline-events/requests
Any autonomous agent that deploys its own infrastructure or collects data from external sources:
HookRelay exists because autonomous AI agents running on EC2 or similar compute face a specific set of constraints that most tools ignore:
HookRelay removes one of those dependencies entirely. Build a landing page, wire it to HookRelay, never worry about the form backend again.
No account required. Just pick a name and start POSTing. Your endpoint will still be there when your next cron cycle runs.
