WEBHOOK INFRASTRUCTURE FOR AGENTS

A URL.
For every agent.

Give any agent a public HTTPS endpoint it owns. Anything that POSTs to it—Stripe, GitHub, a customer, another agent—is accepted, stored durably, signed and delivered to your agent with retries. Read it any time over the API, even when the agent was offline. Agents can even pay for themselves.

$5/month. No existing AGNT account or app subscription required.

  -d '{"event":"order.paid","id":42}'

# 202 { "eventId": "…", "state": "stored" }

Every event is stored before it is acknowledged, delivered to your receiver with an HMAC signature, and kept for your plan's retention window.

Your agent works.
Its URL stays up.

Agents pay for themselves

No card, no browser, no click. An agent signs up over HTTP, pays 10 USDC on Base with one x402 request, buys a plan and starts receiving. The docs show the exact script.

Durable before acknowledged

An event is written to disk and billed exactly once before the sender gets a 202. Idempotency keys and content hashes stop duplicates. Nothing is lost while your agent is down.

Signed delivery, sane retries

Register a receiver and every event arrives with an HMAC-SHA256 signature. Retries back off, dead receivers are paused after repeated failure, and one click resumes them.

Replay, tail, export

Watch events land in your account page, replay any event to your receivers, or export an endpoint's history as NDJSON. Your own events can be emitted to subscribers the same way.

Per account, shared across endpoints. One accepted inbound event or one event delivered to one receiver is one unit. Reads are free. Bodies up to 256 KB; 250 MB, 1 GB or 3 GB of pooled storage by plan. Monthly units reset on day 1 UTC. Hosting is prepaid from credit; optional renewal never charges a card automatically. Upgrades cost the full monthly price difference and retain the existing expiry. Events past your retention window are purged; export first if you need them.

PLANS & USAGE

Simple, predictable pricing.

Choose the plan below. Endpoint counts, events received and delivered each month, and retained storage are pooled per account.

Create an account → verify your email → add credit ($10 minimum) → activate $5/month hosting → create your endpoint. Remaining credit stays in your balance.

DEVELOPER QUICKSTART

Start with a request.

One API for signup, endpoints, events, receivers and usage.

HTTP API

Clear boundaries.
No surprises.

Can I use my own domain?

Not yet. Endpoints live on webhooks.agnt.gg. Customer domains will be available after verification and delivery tests pass.

How do I pay?

Add prepaid credit through Stripe Checkout with a card or a supported stablecoin wallet. Or let the agent do it: one x402 request pays 10 USDC on Base and the credit lands on the same balance—no browser, no human. Hosting is then $5, $15 or $39 a month from that credit.

What can senders POST?

JSON, form-encoded or plain text bodies up to 256 KB. We never execute, fetch or follow anything inside a body; it is stored as bytes and handed to you. Each endpoint has its own rate limit by plan.

What happens if hosting expires?

New events are refused with 402 and endpoint creation pauses. Stored events remain readable until their retention window ends, and purchased credit is preserved.

Give your agent a public address.

Keep account controls with you. Put webhooks to work.
