Agent Spend Desk

Approval and receipts before AI agents spend or hand off work.

Agent Spend Desk is the services-led offer around Boundary Guard: map one agent payment, handoff, write, send, or downstream action; place the checkpoint; then keep the receipt an operator can review later.

The buyer problem

Agents can pay

x402 makes paid API access native to an HTTP request. The next problem is what the agent is allowed to do after access clears.

Operators need a checkpoint

Before a model writes, sends, routes, purchases, or hands work to another agent, the operator needs an allow/retry/block decision.

Teams need proof

A receipt should show what was requested, what policy ran, what happened next, and why the action was allowed, retried, or blocked.

Commercial packages

Workflow Reliability Audit

$3,500

Five-day fixed-scope review of one agent spend, handoff, support, routing, or tool-action workflow. Payment is due before kickoff; audit work starts after scope and non-sensitive examples are confirmed.

Checkpoint Implementation Sprint

$9,500

Insert Boundary Guard into one selected workflow with policy config, deterministic receipts, and acceptance tests.

Checkpoint Proof Retainer

$4,000/mo

Monthly receipt review, policy tuning, replay set, QA note, and buyer-safe proof-pack refresh.

What you get for $3,500

A five-business-day audit of one named agent spend, handoff, routing, write, send, purchase, or tool-action workflow. This is not a generic checklist. The work product is a buyer-safe review artifact that says where the checkpoint belongs, what should be recorded, and what should happen before the next agent acts.

Workflow and risk map

  • One scoped workflow and one named side effect.
  • Hot-path map from payment or trigger to downstream action.
  • Risk points where spend, data, writes, sends, or handoffs can go wrong.

Checkpoint design

  • Recommended checkpoint placement.
  • allow, retry, and block policy matrix.
  • Request/response contract and receipt fields without secrets or customer data.

Replay and proof pack

  • Synthetic replay set for success, retry, and block cases.
  • Example deterministic receipts for internal review.
  • Buyer-safe summary your team can share with product, security, or customers.

Implementation path

  • Concrete next-step recommendation.
  • What to implement now, defer, or exclude.
  • Scope for a checkpoint implementation sprint if the audit finds a real insertion point.

Who this is for / not for

For
  • x402 builders with live or near-live paid endpoints.
  • Agent wallet, payment, authorization, or spend-control teams.
  • API marketplaces, agent service catalogs, and paid-tool routers.
  • Data, content, scraping, onchain, or compliance-aware APIs where agents may act on the result.
  • Founders, CTOs, product leads, DevRel leads, and engineering owners who need a credible review artifact.
Not for
  • Pure read-only demos with no spend, write, send, purchase, route, or handoff risk.
  • Hobby projects that only need a generic AI safety checklist.
  • Token hype campaigns without a real paid workflow owner.
  • Teams that want open-ended consulting instead of one bounded workflow.
  • Buyers who need production SLA, legal certification, or broad compliance sign-off from a five-day audit.

Live proof boundary

What the audit produces

Risk map

The highest-risk action or handoff, plus the fields and policies that should decide allow, retry, or block.

Checkpoint spec

Request/response contract, receipt fields, policy version, and insertion point for engineering review.

Proof story

A buyer-safe before/after narrative showing how the workflow becomes auditable without claiming fake production traction.
