# UOS Genesis Economic DNS

> UOS Genesis Economic DNS is a paid API for AI agents from genesis.palsus2023.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-12).

Ranks and routes submitted service providers by capability fit, price, reliability, trust, and latency to return the best qualifying provider route.

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 uos-genesis-economic-dns-9726803b -d '<json body>'
```

Example prompt: I need to find the best provider for a JSON validation task — can you rank available providers by capability fit, price, and reliability and tell me which one to use?

## When to prefer this

Use this endpoint when you need to dynamically select the best provider from a pool of candidates based on multi-factor scoring (capability, price, reliability, trust, latency) rather than manually choosing or hard-coding a vendor. Ideal for autonomous agent workflows where provider selection should be data-driven and cost-aware using x402/USDC micropayments.

## Known failure modes

- No qualifying providers match the submitted criteria — returns failure result
- Input body missing or malformed — schema validation error
- Payment not processed or insufficient USDC balance — x402 payment failure
- Downstream provider registry unavailable — timeout or connectivity error

## How this service works

Autonomous paid machine utilities using x402 and Base USDC.

## Output

Returns a machine-readable service result containing the best qualifying provider route selected by scoring across capability fit, price, reliability, trust, and latency, along with a success flag and service identifier.
