Payments Ask"Did It Move?"Paybond Asks"Should It?"

Every AI purchase is authorized against budget and policy before it happens — and checked against proof after.

Moving money is not the same as governing a transaction

A rail can confirm that $197.50 moved. It cannot prove who delegated the agent, which policy allowed the purchase, whether the booking completed, or why funds were released.

  1. Who delegated this agent's authority?
  2. Which budget and policy allowed the call?
  3. What evidence satisfied completion?
  4. Can Finance replay the release or refund?

One transaction. Four product jobs.

Kit integrates. Harbor authorizes and settles. Ledger records. Signal builds standing from verified outcomes.

  1. Integrate

    Kit

    Wrap paid tools with the signed intent, scoped capability, and evidence hooks.

  2. Authorize & settle

    Harbor

    Check authority, budget, and policy before execution; use evidence to release or refund.

  3. Record

    Ledger

    Preserve the agreement, evidence references, and state transitions in signed history.

  4. Build standing

    Signal

    Derive Portable Receipts and standing from verified settlement, not self-reported claims.

Guard a paid tool at the boundary

Authorize against the signed intent, budget, and policy before execution. Submit the result as evidence before settlement closes.

const decision = await paybond.authorize(toolCall);const result = await tool.execute(args);await paybond.verify({ evidence: result });

Govern the side effect, not the model

Put the same authority, budget, and evidence boundary around paid actions across runtimes.

  • Travel

    Cap fare, route, and class before booking; settle only after confirmation evidence.

  • Cloud & SaaS

    Bound paid API calls, seat purchases, and provisioning before usage reaches the bill.

  • Procurement

    Escrow vendor budget against signed scope, then release, refund, or dispute from evidence.

  • Finance operations

    Apply delegated limits and approval thresholds, then export a replayable settlement record.

Rails tell you what moved. Paybond records why it was allowed.

An agent books a $742 hotel stay.

Without Paybond

$742 captured — with no signed authority, completion evidence, or release decision.

With Paybond

  • $1,000 delegated travel budget
  • Hotel and rate policy passed before booking
  • Confirmation evidence evaluated
  • Settlement released against the agreement
  • Signed receipt ready for audit or dispute

Portable Receipt

Finance should not have to reconstruct an agent's decision.

Paybond binds authority, policy, evidence, and settlement into one signed record that can leave the live application and still be verified.

  • Verify the signed record outside the console
  • Replay agreement, evidence, and outcome in a dispute
  • Keep raw prompts and evidence out of the receipt envelope

Keep your runtime. Keep your payment rails.

Paybond inserts the authorization, evidence, and settlement lifecycle at the paid-tool boundary without replacing the systems on either side.
