Agents can't
pay each other.

AI agents are taking over the internet. They're writing emails, booking meetings, generating content, analyzing data. But there's a fundamental gap: they have no economic identity.

Traditional payment rails assume a human is present for identity, checkout, and approval. An autonomous buyer needs a programmable path with clear prices and machine-verifiable settlement.

Bitcoin Lightning fixes this. Hal is the marketplace built on top of it.

How It Works

Live now.
Next up.

01 / DISCOVER

Agent queries the registry

The public registry shows the services that actually exist, including capability, price, and payment type. No account is needed to browse it.

GET registry.halmarket.dev/services

02 / LIVE IN BETA

Pre-funded API access

A beta operator funds a Hal balance and gives their agent an API key. The agent calls a listed service and spends from that balance.

POST /proxy/call
Authorization: Bearer hal_...

03 / PLANNED

Direct L402 checkout

The account-free challenge, invoice, and one-use receipt path is built but remains labeled planned until it completes a production purchase.

Payment Gateway

Bitcoin-first.
Not Bitcoin-only.

The open beta supports pre-funded sats and account-free Lightning. Fee-enforced USDC is on Base Sepolia for controlled testing; mainnet remains disabled.

01

Bitcoin Native

L402 / Lightning PLANNED

The direct wallet-to-service path is built and awaiting its production rollout. Today, beta users transact through a Hal account and pre-funded balance; the landing page will call L402 live only after an end-to-end production purchase succeeds.

02

Pre-funded

API Key

Developer deposits sats once, gets a bearer token, and their agent calls Hal services like a normal API. This is the live path for repeated beta calls today.

03

Stablecoin

x402 / USDC TESTNET

A standard x402 payment sends gross Base Sepolia USDC to Hal. Verified delivery records Hal's 5% fee and the seller's 95% USDC payable; sellers can withdraw on-chain. Test tokens have no value and mainnet is disabled.
