# Agent Data APIs – Rental Listing Analysis > Agent Data APIs – Rental Listing Analysis is a paid API for AI agents from 192.3.171.233, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-15). Analyzes a target rental property against caller-supplied comparable listings and public market benchmarks (Zillow ZORI, HUD FMR) to produce a market-position verdict, confidence score, and evidence trail. ## Facts - Endpoint: POST https://192.3.171.233/v1/rentals/analyze - Price: $0.03/call - Payment: x402 - Status: unknown - Last checked: 2026-09-15 - Activations on Zero: 0 - Tags: x402 - Canonical page: https://www.zero.xyz/c/agent-data-apis-rental-listing-analysis-69e79cd0 - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_MgkIaHE43t9E7Y6M25kqR 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 agent-data-apis-rental-listing-analysis-69e79cd0 -d '' ``` Example prompt: Analyze whether the 2-bedroom unit at 600 Guadalupe St, Austin TX 78701 with a base rent of $2,350/month and $150 in mandatory fees is above, at, or below market — compare it against these three nearby comparable listings I'm authorized to share and include Zillow ZORI and HUD Fair Market Rent context for that ZIP code. ## When to prefer this Prefer this endpoint when you need a structured, evidence-backed market-position verdict for a specific rental unit — especially when you have caller-authorized comparable listings to submit alongside public benchmarks. It is purpose-built for agents operating in rental market workflows that require attribution chains, content hashes, and provenance-aware analysis combining Zillow ZORI, HUD FMR, and proprietary feeds. Use it over generic search or lookup endpoints when you need a computed verdict (ABOVE/AT/BELOW market) with a confidence score rather than raw data. ## Known failure modes - Unsigned or credential-less request returns HTTP 402 with x402 payment challenge before any validation - Invalid credentials or requests that cannot produce the advertised minimum result are rejected before payment and not charged - Insufficient or zero comparable candidates may yield LOW confidence band or rejection - Malformed target or candidate objects return validation errors - ZIP code not covered by ZORI or HUD data returns partial market context with warnings - Truncated or non-deduplicable candidate array reduces verdict reliability ## How this service works An x402-paid API suite for autonomous agents. The freight operation preserves deterministic U.S. DOT/FMCSA carrier checks. A self-contained rental market snapshot returns available public rent benchmarks, trends, provenance, and optional budget fit from a ZIP code and bedroom count. Other rental operations normalize, deduplicate, search, compare, and analyze rental observations supplied by a caller who is authorized to process them. Zillow Research ZORI, U.S. Census ZCTA geography, and HUD Fair Market Rent data are not represented as unit-level listings or executed lease rents. Unsigned requests receive the x402 challenge before validation. Credential-bearing retries that are invalid or cannot produce the advertised minimum result are rejected before payment verification and settlement and are not charged. ## Output Returns a JSON object containing: a market verdict string (e.g. ABOVE_MARKET), a confidence band (LOW/MEDIUM/HIGH) with a numeric score, an array of ranked comparable evidence items with attribution and content hashes, market context from Zillow ZORI (typical rent, 1/3/12-month % change, as-of date), HUD Fair Market Rents by bedroom count, geographic coordinates, HUD area name and code, dataset version, a unique analysis ID, and an array of warnings about data limitations. ## Request schema (JSON Schema) ```json { "type": "object", "properties": { "policy": { "type": "object" }, "target": { "type": "object" }, "candidates": { "type": "array", "items": { "type": "object" } } } } ``` ## Response schema (JSON Schema) ```json { "type": "json", "example": { "market": { "evidence": [ { "id": "ev_zori", "dataset": "Zillow Observed Rent Index (ZORI)", "sourceId": "zillow-research", "sourceUrl": "https://rentals.example/listings/AUS-1200-12A", "fieldPaths": [ "/typicalRentCents" ], "observedAt": "2026-08-23T16:00:00Z", "attribution": "Caller-authorized property manager feed", "contentHash": "sha256:ccdbf127d9e36d25f3c0e535a3cb4280c7b67117399e6fe42a41a914f1c9087a", "retrievedAt": "2026-08-24T12:05:00Z" } ], "latitude": 30.2713, "warnings": [ "Market benchmarks are area-level context and are not substitutes for property-level comparables." ], "longitude": -97.7426, "postalCode": "78701", "generatedAt": "2026-08-24T12:00:00Z", "hudAreaCode": "METRO12420M12420", "hudAreaName": "Austin-Round Rock-Georgetown, TX HUD Metro FMR Area", "sourceCount": 2, "datasetVersion": "rental-ds-2026-08-24-6af7130e", "change1MonthPct": 0.3, "change3MonthPct": 1.1, "typicalRentAsOf": "2026-07", "change12MonthPct": -0.8, "typicalRentCents": 229400, "hudFairMarketRentsCents": { "0": 143000, "1": 160000, "2": 195000, "3": 254000 } }, "target": { "address": { "city": "Austin", "unit": "901", "line1": "600 Guadalupe St", "state": "TX", "postalCode": "78701" }, "bedrooms": 2, "latitude": 30.2704, "bathrooms": 2, "longitude": -97.7462, "squareFeet": 1020, "propertyType": "MULTIFAMILY", "baseRentCents": 235000, "mandatoryMonthlyFeesCents": 15000 }, "verdict": "ABOVE_MARKET", "evidence": [ { "id": "ev_listing_1", "dataset": "Rental listing observation", "sourceId": "property-manager-feed", "sourceUrl": "https://rentals.example/listings/AUS-1200-12A", "fieldPaths": [ "/topComparables/0" ], "observedAt": "2026-08-23T16:00:00Z", "attribution": "Caller-authorized property manager feed", "contentHash": "sha256:ccdbf127d9e36d25f3c0e535a3cb4280c7b67117399e6fe42a41a914f1c9087a", "retrievedAt": "2026-08-24T12:05:00Z" } ], "warnings": [ "The estimate uses asking-rent observations, not executed lease rents.", "The confidence score is heuristic and uncalibrated; inspect the returned comparables." ], "analysisId": "anl_78e2ee30bfb1ee2f394f", "confidence": { "band": "MEDIUM", "score": 78, "method": "HEURISTIC_V1_UNCALIBRATED", "factors": [ { … (truncated) ``` ## More - Live health (JSON, refreshed every minute): https://www.zero.xyz/c/agent-data-apis-rental-listing-analysis-69e79cd0/health.json - [Zero catalog index](https://www.zero.xyz/llms.txt) - [Other services from 192.3.171.233](https://www.zero.xyz/host/192.3.171.233/llms.txt)
