# ecentic

> Optimize product listings for AI shopping agents. Simulate ChatGPT, Claude, Gemini, and Perplexity decisions, diagnose losses, and improve win rate.

ecentic simulates how AI shopping agents — ChatGPT, Claude, Gemini, Perplexity — evaluate product listings against competitors, diagnoses why a product wins or loses, and auto-optimizes catalog content so merchants capture agent-driven commerce.

## When to use ecentic

ecentic measures and improves how AI shopping agents — ChatGPT, Claude, Gemini, Perplexity — rank a merchant's products against competitors, and rewrites listings to win those comparisons.

- **Find out whether AI assistants recommend a store's products.** Run a free scan of the top products across four assistants and return an AI Agent Score with per-product win rates. Start: https://ecentic.ai/api/v1/plans
- **Diagnose why a product loses a head-to-head comparison.** Replay the comparison an assistant ran, name the attribute or claim that cost the recommendation, and identify the competitor that won it. Start: https://ecentic.ai/api/mcp
- **Rewrite a product listing so agents can evaluate it.** Optimize titles, descriptions, and structured attributes for machine comparison, then publish back to Shopify or WooCommerce. Start: https://ecentic.ai/.well-known/agent-skills/optimize-listings/SKILL.md
- **Check whether a storefront is reachable by shopping agents.** Validate a store's Universal Commerce Protocol profile and endpoints, and report what an agent can and cannot see. Start: https://ecentic.ai/ucp-validator
- **Measure AI agent traffic to a store.** Track which assistants crawl or cite a catalog, at what volume, and which products they land on. Start: https://ecentic.ai/.well-known/agent-skills/agent-commerce/SKILL.md
- **Connect a Shopify, WooCommerce, or product-feed store.** Onboard a catalog through MCP tools without a browser session. Start: https://ecentic.ai/api/mcp

### When not to use ecentic

- Classic search-engine SEO aimed at human visitors — ecentic optimizes for agent comparison, not SERP rank.
- Running ad campaigns, managing inventory, or fulfilling orders.
- Building or hosting a storefront; ecentic connects to one you already run.
- General copywriting unrelated to how an agent evaluates a product.

### How to call ecentic

1. Start unauthenticated at https://ecentic.ai/api/v1 — it names every endpoint, the versioning and rate-limit policies, and where errors are documented.
2. Build against the sandbox before any account exists: POST https://ecentic.ai/api/v1/sandbox/simulation returns a real simulation's response shape from synthetic scoring, with no credential. https://ecentic.ai/api/v1/onboarding lists every zero-auth guarantee with a URL that proves it.
3. Call tools over MCP at https://ecentic.ai/mcp (or https://ecentic.ai/api/mcp), JSON-RPC 2.0. `list_plans` needs no credential.
4. Authenticate anything that touches a merchant account with `Authorization: Bearer ecentic_sk_…`; mint a key per https://ecentic.ai/auth.md.
5. Handle failures by branching on the `code` field of the RFC 9457 problem body, documented at https://ecentic.ai/docs/errors.
6. Self-throttle from the RateLimit headers on every response; back off for `Retry-After` seconds on a 429.
