Callable Audit

Callable Audit

Assess whether a business can be reached, evaluated, and transacted with by an AI agent without a human re-routing through a UI. Returns a per-surface score and a verdict.

When to Invoke

Trigger on: "callable audit", "is this business callable", "can an agent transact here", "agent-commerce readiness", "agent-accessible", "discoverable by agents", or when a user provides a business name/URL and asks how agent-ready it is from a buyer's perspective.

Inputs

Accept any of:

• A business name (e.g. "Shopify")
• A URL (homepage, pricing page, or checkout flow)
• A product/service description in free text

If multiple surfaces exist (website, API docs, MCP server, plugin), audit each surface separately.

Phase 1: Surface Discovery

Identify all agent-reachable surfaces the business exposes:

If a URL is provided, fetch and inspect it. If only a name, reason from publicly known documentation.

Phase 2: Economic Task Completion Rubric

Score each step of the full economic task. For each step: 1 = impossible without a human, 3 = partially automatable, 5 = fully agent-operable.

Step 1 — Discover (Can an agent find this business and its offerings?)

• Is the business indexed in a way agents can retrieve? (LLM training data, web search, agent directories)
• Are products/services described in machine-readable structured data?
• Is there an MCP server, plugin manifest, or API the agent can call directly?

Step 2 — Compare (Can an agent evaluate options against criteria?)

• Are pricing, features, and constraints machine-readable?
• Are comparison attributes (specs, tiers, SLAs) in a structured format?
• Can an agent filter/query the catalog programmatically?

Step 3 — Decide (Can an agent make a selection without ambiguity?)

• Is the selection interface (add-to-cart, configure, quote request) API-accessible?
• Are decision inputs well-typed (required fields, validation rules exposed)?
• Can the agent complete configuration without a visual UI?

Step 4 — Pay (Can an agent authorize and complete a transaction?)

• Is there a payment endpoint the agent can call (Stripe Link, agent-payment token, B2B purchase order API)?
• Are spend caps and authorization delegation supported?
• Is idempotency supported (agent can retry without double-charging)?

Step 5 — Confirm (Can an agent receive and verify order confirmation?)

• Does the business return a structured confirmation (JSON receipt, order ID, tracking reference)?
• Is there a status-check endpoint the agent can poll?
• Is the confirmation machine-readable without screen-scraping?

Phase 3: Auth & Security Assessment

Assess the authentication model for agent compatibility:

• API key: Supported and documented? (agent-friendly)
• OAuth 2.0 / PKCE: Supported? (agent-friendly with proper delegation)
• Session cookies / CAPTCHA: Requires human browser session? (agent-hostile)
• Agent payment tokens: Scoped spend tokens supported? (future-proof)

Note any fraud or rate-limit controls that would block legitimate agent traffic.

Phase 4: Score & Verdict

Calculate the overall score:

Per-surface score = average of 5 step scores (1-5 scale)
Overall score = average across all surfaces

Verification

A good audit:

• Scores all 5 economic task steps with evidence, not assumptions
• Identifies the specific blocking step (usually Pay or Confirm for most businesses)
• Does not rate a business "Agent-Callable" if Pay requires a human browser session
• Recommended path items are specific and actionable (not "add an API")
