Every decision, stamped
Each route and preflight persists an audit event and a content-addressed sha256 proof hash — what was asked, checked, chosen, and why.

Pre-flight confidence for your agent force.
You are giving agents budgets. Stackbroker is the policy and audit layer that clears every purchase first — GO, HOLD, or NO-GO — so autonomy never means spending blind.
The fear, by role.
The same clearance layer resolves a different fear for each seat at the table.
| Role | The core fear | What clearance gives you |
|---|---|---|
| CFO & CIO | Runaway API spend, compliance leaks, ungoverned agent purchases. | Hard budget caps, confirmation thresholds, anomaly flags, and a proof trail finance can read back. |
| Platform & infra teams | Hard-coding fragile vendor choices and fallbacks into every agent. | One call — /v1/route — that ranks candidates, applies policy, and returns reasoned fallbacks. |
| Consultants & MSPs | Delivering autonomous client systems that carry financial liability. | An auditable procurement trail that proves vendor choice and fleet performance to stakeholders. |
What you can enforce.
- 01
Spend boundaries
Per-request price ceilings, approved-spend budgets, and confirmation thresholds that force a human HOLD above the line.
max_price_usdc · approved_spend_usdc · require_confirmation_above_usdc
- 02
Capability risk
Block whole classes of risk — PII processing, code execution, financial actions, browser control — regardless of which vendor offers them.
blocked_policy_flags: [pii_processing, code_execution, financial_action, browser_control]
- 03
Trust floors
Require a minimum attestation tier and restrict payment rails, so agents only transact with services that meet your evidence bar.
require_attestation_tier: probed | verified | attested · allowed_payment_rails
- 04
Drift detection
Spend anomalies and context shifts — an agent suddenly spending 5x baseline, or silently switching vendors — surface as HOLD, not as a surprise on the invoice.

What you can prove.
Governance is only real if you can read it back later.
Readable by finance
Audit lookups and a governance event stream give finance and compliance the same record the agent acted on. No reconstruction, no vibes.
Vendor truth over time
Outcome telemetry — quoted vs. actual price, latency, downstream success — replaces star ratings with evidence you can act on.
Built as a SaaS layer, run like infrastructure.
