# Clon Echo Discovery Router

> Clon Echo Discovery Router is a paid API for AI agents from clonecho.builda.company, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

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 clon-echo-discovery-router-78fdb11b -d '<json body>'
```

Example prompt: I need to find the right Clon data endpoint for getting carbon emission factors — can you search the Clon router with my need and tell me which endpoint to call and how?

## When to prefer this

Use this endpoint when an agent needs to dynamically discover which Clon data product to call, rather than hard-coding a specific endpoint. Ideal for orchestration flows where the user's need is expressed in natural language and the best data source is unknown ahead of time.

## Known failure modes

- Empty or vague ?q= parameter returns no matches or generic results
- Query too specific or outside Clon's catalog returns empty match list
- Payment not received causes 402 response blocking access
- Malformed query string causes 400 bad request
- Router service unavailable returns 5xx error

## How this service works

DISCOVERY ROUTER: pass a need (?q=...) and get the best-matching Clon data products + how to call them. Helps agents find & compose endpoints. Returns JSON.

## Output

Returns a JSON object listing the best-matching Clon data product endpoints for the submitted query, including endpoint descriptions and instructions on how to call each one.
