Hive Joins the Internet-Native Payment Revolution - Introducing hive-x402
Something significant has been quietly taking shape at Ecency and Hive, and today I want to share it with the community.
Over the past weeks We've been working on bringing Hive - and specifically HBD - into a new open payment standard that is gaining serious traction across the Web3 and AI ecosystem: **x402**.

What is x402?
-------------
x402 is an open protocol built on top of the standard HTTP stack. It revives the long-dormant HTTP `402 Payment Required` status code and turns it into a fully functional machine-to-machine payment layer. When a client - whether a human app, an AI agent, or any automated service - requests a resource, the server responds with `402` and payment instructions. The client pays, retries, and gets access.
No accounts. No API keys. No credit card forms. Just HTTP and a signed payment payload.
Coinbase launched the protocol, Cloudflare joined as a foundation partner, and it's Apache-2.0 licensed and genuinely permissionless. Any network can implement it.
What We've Built
----------------
### 1\. Hive Namespace in ChainAgnostic (merged)
The x402 protocol uses CAIP-2 chain identifiers to specify which network a payment settles on - for example, `eip155:8453` for Base. For Hive to participate as a first-class network, it needed a proper namespace registration in the cross-chain standard.
[**PR #174**](https://github.com/ChainAgnostic/namespaces/pull/174) to the [ChainAgnostic/namespaces](https://github.com/ChainAgnostic/namespaces) repository has been merged. It adds:
* A **CAIP-2 profile** for Hive chain identifiers (`hive:mainnet`)
* A **CAIP-10 profile** for Hive account identifiers (human-readable names, not hex addresses)
This is foundational work. Any protocol, wallet, or tool using CAIPs can now reference Hive natively and unambiguously.
### 2\. Hive Scheme Spec in x402 Core (under review)
[**PR #1330**](https://github.com/coinbase/x402/pull/1330) to the main `coinbase/x402` repository adds Hive as a supported network in the `exact` payment scheme specification. It introduces:
* `specs/schemes/exact/scheme_exact_hive.md` - a full scheme spec covering payload structure, secp256k1 signature verification against on-chain active key authorities, and settlement via direct transaction broadcast
* Updates to the core `scheme_exact.md` to include Hive in the network reference list and critical validation requirements
This is a specification-only PR - the reference implementation is already complete and published separately. If you have some github (hive) power, feel free to leave a comment and encourage faster review. 😀
### 3\. hive-x402 - The Full Implementation
The complete package lives at [**ecency/hive-x402**](https://github.com/ecency/hive-x402), is published on npm as [**@hiveio/x402**](https://www.npmjs.com/package/@hiveio/x402), and has a public facilitator running live at [**x402.ecency.com**](https://x402.ecency.com).
It includes everything needed to participate in the x402 ecosystem from the Hive side:
**Facilitator server** - verifies secp256k1 signatures against a Hive account's on-chain active keys, broadcasts HBD transfers, and tracks nonces to prevent replay attacks. Ships with SQLite out of the box and Redis for production. The public instance at x402.ecency.com is free to use.
**Express, Next.js, and Hono middleware** - gate any API endpoint behind an HBD micropayment with a single function call:
```js
app.get("/api/premium", paywall({
amount: "0.050 HBD",
receivingAccount: "your-hive-account",
facilitatorUrl: "https://x402.ecency.com",
}), handler);
```
**Client library** - transparently handles the full `402 → sign → retry` flow for AI agents and apps. Also ships browser-compatible building blocks for signing via Hive Keychain or HiveAuth without any Node.js dependencies.
```js
const client = new HiveX402Client({
ac
