## 4. Engineering Guides & Architecture Blueprints

### Trustpilot API Pricing (2026): Enterprise Add-On Costs vs $0.08/1K Developer REST API
- **URL**: https://reviewsdataapi.com/guides/trustpilot-api-pricing
- **Summary**: Complete 2026 breakdown of official Trustpilot Business API pricing ($600–$1,500+/mo add-on) vs ReviewsData API ($0.08–$0.20 per 1,000 verified Trustpilot reviews, no contract).
- **Key Takeaways**:
  - Official Trustpilot API keys are not sold standalone: they require an annual Trustpilot Business contract plus the Connect API add-on.
  - Official OAuth keys cannot extract full paginated reviews or aspect sentiment across competitor or third-party merchant domains at scale.
  - ReviewsData API provides GET /v1/trustpilot/reviews (2 Credits / review = $0.08–$0.20 per 1K) and GET /v1/trustpilot/company (10 Credits / profile) with 0 annual commitments.
  - Every response includes a pre-computed 5-star histogram, positive/defect polarity tags, verification level, and company replies.

### Yelp Fusion API Pricing (2026): Why 3 Truncated Reviews Cost $19.99/1K & How to Fix It

- **Summary**: Analyze Yelp Places / Yelp Fusion API 2026 pricing ($7.99–$19.99 per 1,000 calls, 3-review excerpt limit, zero caching) vs ReviewsData API ($0.08–$0.20 per 1,000 full reviews).
- **Key Takeaways**:
  - Official Yelp Fusion /businesses/{id}/reviews still returns only 3 160-character excerpts regardless of whether you pay $14.99/1K or $19.99/1K.
  - Yelp's API Terms prohibit storing review text in analytics warehouses, vector databases, or LLM training/RAG indexes beyond 24 hours.
  - ReviewsData API exposes both clean /v1/yelp/{search,reviews} endpoints AND drop-in /v3/businesses/* compatibility routes.
  - Full-length Yelp reviews with useful/funny/cool vote counts and owner replies cost 2 Credits ($0.0002) per review—0 Credits on empty.

### TripAdvisor Content API Alternative (2026): Unlock Ranked Restaurants, Hotels & Geo IDs

  - GET /v1/google-play/reviews works on any public Android package ID across global country and language storefronts.
  - Includes app_version on each review so mobile release teams can detect crash or billing regressions immediately after a rollout.
  - Pre-computed sentiment_summary surfaces positive praise vs defect pain-point tags automatically.

## 6. Frequently Asked Questions

### How does the $1 = 10,000 Credits pricing model work?

ReviewsData API uses a transparent record-based credit system where $1.00 = 10,000 Credits. All four review stream endpoints (/v1/trustpilot/reviews, /v1/yelp/reviews, /v1/google-play/reviews, and /v1/app-store/reviews) cost 2 Credits per review returned ($0.20 per 1,000 reviews base, or $0.08 per 1,000 reviews on the Business plan). Trustpilot company profiles (/v1/trustpilot/company) cost 10 Credits flat. Yelp and TripAdvisor discovery searches cost 5 Credits per returned business or hospitality record. Empty results or failed calls always cost 0 Credits.

### How does ReviewsData API compare to Trustpilot Business API, Yelp Fusion, Birdeye, and Outscraper?

Trustpilot's official Business API requires an enterprise software contract ($15,000+/yr) and restricts queries to domains you own. Yelp Fusion v3 caps review endpoints to 3 short excerpts and charges $7.99–$14.99 per 1,000 calls on commercial tiers. Birdeye and Yext lock teams into $299–$450/month seat contracts, while Outscraper charges up to $2.00 per 1,000 reviews with slow async webhook queues. ReviewsData API unifies Trustpilot, Yelp, TripAdvisor, Google Play, and Apple App Store into one synchronous JSON & MCP API starting at $0.08–$0.20 per 1,000 reviews — with a $9 Indie Starter Pack and zero contracts.

### Does every review endpoint return star histograms and aspect sentiment polarity automatically?

Yes. Every response from /v1/trustpilot/reviews, /v1/yelp/reviews, /v1/google-play/reviews, and /v1/app-store/reviews includes both individual review sentiment scores (polarity_score from -1.0 to +1.0) and an aggregated sentiment_summary object containing 5-star to 1-star counts, star percentages, net polarity score, and aspect-level tags (such as Customer Support, Speed & Delivery, Ease of Use & UX, Quality & Reliability, and Pricing & Billing) at zero extra credit cost.

### What is the response latency for cached vs. live real-time review queries?

Warm queries hitting our Redis L1 + PostgreSQL 16 L2 reputation cache respond in 20–45 ms. Cold queries execute synchronously against our dual-rail upstream connectors (200–650 ms on Apple App Store & Google Play direct feeds; 1.1–1.8 seconds on Trustpilot, Yelp & TripAdvisor) and automatically write through to PostgreSQL so repeat reads are instant.

### Can I migrate from Yelp Fusion API v3 without rewriting my request paths?

Yes. In addition to /v1/yelp/search and /v1/yelp/reviews, our gateway natively accepts GET /v3/businesses/search and GET /v3/businesses/{id_or_alias}/reviews. Simply point your base URL to https://api.reviewsdataapi.com and pass your rv_live_... key in Authorization: Bearer or x-api-key — and you immediately unlock full-length Yelp reviews beyond the 3-excerpt limit.

### Am I charged when a query returns 0 reviews or when an API request fails?

Never. Queries that return 0 reviews or 0 businesses cost 0 Credits. Invalid parameters (HTTP 400), unfound identifiers (HTTP 404), rate-limited requests (HTTP 429), and upstream errors (HTTP 5xx) always deduct 0 Credits.

### Should I choose a Monthly Subscription or a Pay-As-You-Go (PAYG) Credit Pack?

Monthly subscriptions ($19 Starter / 240k credits, $69 Growth / 1M credits, $199 Business / 5M credits) include +26% to +151% bonus credits, bringing your effective cost down to $0.08 per 1,000 reviews. If you prefer zero recurring charges, start with our $9 Indie Starter Micro-Pack (90,000 never-expiring credits = 45,000 reviews) or larger PAYG packs ($25, $89, $249).

### What are the RPM rate limits and concurrency allowances?

Free Sandbox accounts include 12,000 Credits ($1.20) at 0 ms plus up to +20,000 Streak bonus credits at 30 RPM (2 RPS). Paid plans unlock production burst concurrency: 60 RPM ($9 Indie Pack), 120 RPM / 5 RPS (Starter), 300 RPM / 12 RPS (Growth), and 600 RPM / 25 RPS (Business).

### What payment methods and tax invoices are supported?

Every new account receives 12,000 instant Free Credits ($1.20) plus up to +20,000 Sandbox Streak credits. For paid top-ups ($9 Indie Starter Pack to $249 Scale) and Monthly Plans ($19–$199/mo), we support instant 0%-fee Multi-Chain Cryptocurrency (USDC, USDT, SOL, ETH, BNB, BTC across Solana, Arbitrum, Polygon, Base/BSC, Tron, and Ethereum) via NOWPayments with an automatic +5% Bonus Credits reward and corporate VAT / Tax ID billing profile records.

### What is your refund policy?

Payments made within the last 14 days are eligible for a pro-rated refund of unused purchased credits. Promotional signup credits have no cash value.
