Subscription billing,
built for autonomous agents.
Scribe Finance is the recurring-payments layer of the machine economy. Agents discover plans, subscribe, and stay within budget on their own: every renewal collected on schedule, every charge settled in USDG on Robinhood Chain, every record written to a ledger anyone can verify.
Your revenue, live from the chain. Settlements, renewals, and plans in one place.
Plans
Publish pricing to the on-chain registry once. Any agent can discover a plan, read its terms, and subscribe: no sales call, no signup form, no key exchange.
- Flat-rate and usage-based tiers
- Terms locked at publication
- Discoverable by any wallet

Robinhood Chain Settlement
Payments clear in well under a second for a fraction of a cent, and every settlement is a public record anyone can audit.

Subscriptions
One on-chain agreement binds a wallet to a plan. Collections then run on schedule, cycle after cycle, with no human in the loop.
Renewals settle themselves, cycle after cycle
Allowances
Set a hard ceiling on what a service can draw from a wallet. The contract enforces the cap; an overrun isn't a policy violation, it's an impossibility.
Hard cap enforced on-chain
Payment Sessions
High-frequency agents open a session once, stream requests against a prepaid budget, and settle the whole batch in a single transaction.
x402 & MPP
Native support for the open standards of machine payments. If an agent can answer HTTP 402, it can pay you today.

Facilitator Network
The facilitator verifies authorizations and executes settlement end to end. You integrate with an SDK call, never with raw chain code.
Anyone can take one payment. Scribe Finance is built for the ten thousand that follow: renewals, metering, budgets, and a receipt for every one.
One import away from any agent framework
Install the SDK, hand your agent a budget, and it can find plans, subscribe, and settle its own invoices. Private keys stay in the wallet layer, where they belong.
$ npm install @scribefinance/sdk
import { scribefinance } from "@scribefinance/sdk"
agent.use(scribefinance({ budget: "25 USDG / mo" }))

USE CASES
Wherever agents spend, Scribe Finance does the billing.
Model gateways, data feeds, tool servers, even other agents: an autonomous customer can hold a subscription to any of them. Scribe Finance keeps each one current: renewals collected on schedule, budgets enforced by contract, and a receipt for every charge written on-chain.
Inference APIs
Sell model access by the call or by the token. Agents subscribe with a wallet: nothing to provision, nothing to revoke.
metered · per call
Data Marketplaces
Price a feed monthly and let subscribing agents keep their own access alive, renewal after renewal, within the budget they were given.
fixed · monthly
Agent Frameworks
Give LangChain, CrewAI, or ElizaOS agents a real billing relationship with the services they call: one hook, no key handling.
sdk · one hook
MCP Servers
Put a metered plan in front of your tools. The facilitator meters, collects, and settles while your server just serves.
metered · per tool call
On-chain Services
Let contracts and keepers bill other agents directly, wallet to wallet, with settlement anyone can trace block by block.

Build on the billing layer
Scribe Finance is developed in the open, alongside the developers wiring autonomous agents into real services. Here is what ships on it today.
An agent that pays its own way
Wire a LangChain or CrewAI agent to the SDK and it can discover a plan, subscribe, and renew for as long as its budget allows.
A paywall in one middleware call
Answer HTTP 402 with your payment terms, verify proofs, and collect renewals, all without writing a line of chain code.
Tools that meter themselves
Charge per MCP tool call with a metered plan while the facilitator handles verification and settlement in the background.
Budgets that cannot be blown
Grant an allowance with a hard cap and an expiry. The contract refuses anything past the limit: no alerting, no clawbacks.
Receipts nobody has to trust
Every subscription and settlement is public state on Robinhood Chain. Audit an agent's spend directly from the ledger.
Agents billing other agents
Publish a plan for a specialist agent and let orchestrators subscribe to it, wallet to wallet, on locked-in terms.
The chain is the source of truth
Scribe Finance keeps no private ledger. Plans, subscriptions, allowances, and every settlement live as public state on Robinhood Chain. Verify a charge, audit an agent, or index the entire history yourself. Nothing has to be taken on faith.
