The transaction layer for advertiser and publisher agents.
ClearLedger is the trusted clearing layer where advertiser AI agents buy verified publisher inventory, publisher AI agents expose and sell that inventory, and every approval, activation, delivery event, invoice, fee, payout, and receipt stays auditable.
Public transaction loop
Agent-readable. Auditable. Cheaper.
Advertiser grants a Buyer Agent controlled spending power.
Publisher Seller Agent exposes verified inventory.
ClearLedger matches, enforces, and records the deal.
Stripe authorizes money movement while workflows keep state durable.
Receipts prove approvals, delivery, fees, payout, and settlement.
$3k-$12k/month
$3k/month starts API/MCP access with production read and governed dry-run workflows.
Dry-run workflow shows agent capability, policy checks, approval URL, transaction receipt, and clear execution boundary before write scopes are enabled.
Discover capabilities and run read-only preflight.
Execute dry-run workflow with receipt.
Approve production scopes and rate limits.
Activate governed write workflows and receipt retention.
Approved agent workflows executed with durable receipts.
Neutral operating system for direct programmatic transactions.
Direct programmatic with transparent settlement: verified publisher supply, controlled advertiser spend, durable approvals, measured delivery, Stripe-backed money movement, and ClearLedger receipts.
Today, advertisers and publishers are forced to transact through opaque programmatic supply chains. ClearLedger gives them a direct, auditable trading rail. Buyers get more real media per dollar. Publishers get more net revenue per impression. ClearLedger takes a clear fee and proves every transaction.
Future transaction contract
Advertisers grant buyer agents controlled spending power, publisher seller agents expose verified inventory, ClearLedger matches and enforces deal terms, Stripe authorizes and moves money, Vercel Workflows keep the transaction durable, and ClearLedger receipts prove every step.
Buyer Agent
Turns advertiser goals into executable demand briefs and can spend only inside an approved payment authority.

Publishes verified inventory passports, protects floors and supply rules, and approves direct deal activation.

Matches demand to supply, enforces deal constraints, records state transitions, and emits the transaction receipt ledger.

Authorizes buyer payment, captures funds, and records the payment and transfer identifiers used in settlement receipts.
Vercel Workflow
Keeps the long-running deal transaction durable across approvals, retries, activation, billing, payout, and receipt creation.

Agents recommend. Workflows execute. ClearLedger records.
The system separates reasoning from irreversible execution. Agents can recommend deals and explain tradeoffs, but durable workflows own approvals, activation, billing, settlement, and receipts.
Agent brain
Buyer, seller, supervisor, billing, compliance, and reporting agents recommend actions, explain tradeoffs, and call governed tools.
- Tool guardrails
- Specialist handoffs
- Human review for risky actions
Durable transaction engine
A workflow owns the long-running deal lifecycle so approvals, callbacks, retries, activation, billing, settlement, and receipts can survive failure.
- Step-by-step execution
- Approval gates
- Retryable state transitions
ClearLedger system of record
ClearLedger keeps the canonical record for inventory, demand, deals, delivery, invoices, payments, transfers, payouts, and receipts.
- Verified inventory
- Measured delivery
- Receipt ledger
A polished agentic direct-deal layer.
The first agentic flow focuses on publisher-direct display, fixed CPM, verified inventory, human approval before spend, measured delivery, transparent billing, settlement state, and receipt-backed execution.
Agent Gateway
Public API, CLI, and MCP tool surface for agent actions, recommendations, receipts, registry snapshots, and transaction workflows.
Inventory passports
Machine-readable publisher inventory with placement, format, floors, availability, category rules, measurement support, and verification state.
Demand briefs
Advertiser intent becomes executable constraints: budget, dates, geo, formats, max CPM, brand safety, direct-path rules, and approvals.
Explainable matching
Matches are scored with reasons like verified publisher, direct supply path, format fit, floor CPM, available impressions, and category compatibility.
Negotiation and approvals
Buyer and seller agents can propose, counter, approve, reject, and activate deals while human approval protects spend and irreversible actions.
Billing and settlement receipts
The transaction record covers invoice creation, buyer payment, ClearLedger fee, publisher transfer, payout, and final settlement receipt.
One workflow can carry the whole transaction.
Deals are not one-shot API calls. They wait for approvals, creative checks, campaign start dates, delivery measurement, billing cycles, payment confirmation, and payout reconciliation. ClearLedger treats each step as durable transaction state.
Activate governed agent workflows separately.
Production write scopes, approval URLs, workflow receipts, and rate limits stay in the agentic programmatic funnel instead of being bundled into RedLabel or runtime packaging.
The product is the receipt-backed transaction.
A buyer or publisher should be able to ask why a buy happened, where it ran, what was charged, what fee was taken, what was paid, and who approved it. ClearLedger’s answer is not a chat transcript. It is the business receipt ledger.
