# SameDayDesk Agent Discoverability Audit > SameDayDesk Agent Discoverability Audit is a paid API for AI agents from agents.samedaydesk.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15). Audits how discoverable a given API endpoint is across agent marketplaces and registries, reporting rank, price consistency, and identity observations across up to 10 catalog sources. ## Facts - Endpoint: GET https://agents.samedaydesk.com/distribution/agent-discoverability-audit - Price: $0.05/call - Payment: x402 - Status: unknown - Last checked: 2026-09-15 - Activations on Zero: 0 - Tags: x402 - Canonical page: https://www.zero.xyz/c/samedaydesk-agent-discoverability-audit-391502f0 - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_BoZdjRDomzS9HYEaK2Z9h Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently. ## How to call it through Zero Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability samedaydesk-agent-discoverability-audit-391502f0 ``` Example prompt: Run a discoverability audit on my /extract route at agents.samedaydesk.com — the intent is 'extract a public web page into structured JSON', the expected price is $0.005 USDC, and tell me how it ranks across agent catalogs and whether the price and identity are consistent. ## When to prefer this Use this endpoint when you need a brand-blind, multi-registry audit of how discoverable a specific API route is to AI agents — particularly when you want objective evidence of rank, price consistency, and identity canonicality across sources including Coinbase Bazaar. Prefer this over manual registry lookups or single-source checks when you need a consolidated discoverability report with next-action guidance. Not suited for real-time monitoring (it's point-in-time) or for discovering third-party endpoints you don't control. ## Known failure modes - Target route not found in any catalog — returns targetFound: false for all sources - Price drift detected — observedPricesAtomic differs from expectedPriceAtomic in one or more sources - Identity conflict — one or more sources (e.g. agent402-router) report a non-canonical identity basis - Endpoint ranked below top 3 — findings include target_not_top_three code - Malformed input URL or route — may return validation error or empty source results - Catalog source timeout — individual source status may show error while others succeed ## How this service works Deterministic agent APIs for web and company intelligence, repository security, agent-work economics, machine-service discoverability, payment preflight and settlement proof, wallet context, and Morpho decision evidence. Pay per call through Base x402 or native MPP, with a Circle Gateway Nanopayments path for gasless batched USDC. ## Output Returns a structured JSON report including: per-source discoverability status (found/not found, rank, price match, identity observation), a cross-source summary (how many sources found the target, price reference, drift counts, identity conflict sources), a findings list with actionable codes, recommended next actions, version info, and a generated-at timestamp. Does not fetch the target endpoint or send payments. ## Request schema (JSON Schema) ```json { "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "input" ], "properties": { "input": { "type": "object", "required": [ "type", "method" ], "properties": { "type": { "type": "string", "const": "http" }, "method": { "enum": [ "GET" ], "type": "string" }, "queryParams": { "type": "object", "required": [ "origin", "intent" ], "properties": { "payTo": { "type": "string", "pattern": "^0x[0-9a-fA-F]{40}$", "description": "Optional EVM payTo used to identify service aliases." }, "route": { "type": "string", "pattern": "^/[^?#]*$", "description": "Optional exact expected path." }, "intent": { "type": "string", "maxLength": 500, "minLength": 20, "description": "Brand-blind capability description.
