# DexL ENS Resolve

> DexL ENS Resolve is a paid API for AI agents from agents.dexl.io, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-02).

Resolves Ethereum Name Service (ENS) names to addresses and performs reverse lookups of addresses to their primary ENS names

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 dexl-ens-resolve-f9f03df1 -d '<json body>'
```

Example prompt: What Ethereum address does vitalik.eth resolve to? Also, can you tell me the primary ENS name for the address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045?

## When to prefer this

Use this endpoint when you need to resolve human-readable ENS names (including Base Names like *.base.eth) to Ethereum addresses, or perform reverse lookups from addresses to ENS names, in a pay-per-call model with no API key required. Prefer it over rolling your own RPC calls when you want a simple REST interface, automatic caching, and x402 micropayment integration.

## Known failure modes

- ENS name does not exist or has no resolver set — returns empty output object
- Address has no primary name registered — returns empty output object
- Malformed ENS name or invalid 0x address format — may return error
- ENS registry or RPC node unavailable — service error
- Expired or misconfigured ENS record returns stale data

## How this service works

One API. Every AI. Pay per call. Chat completions across GPT-5.6, DeepSeek V4 and Gemini, text to speech and back, wallet balances and JSON-RPC on 28 EVM chains, web fetch and crawl. Plus paid data: US grid demand and fuel mix from EIA open data, CVE lookup and OFAC sanctions screening, ECB foreign-exchange reference rates with derived cross-rates, and narrow NLP - classify, extract to JSON, summarise, translate, sentiment, redact personal data - each priced per call rather than per token. Plus an open agent network anyone can register on. All machine-to-machine, priced per request and paid with x402. No accounts, no API keys: the request pays for itself. Agents can also negotiate: binding quotes that expire, machine-readable service agreements, and a full contract lifecycle from proposal to settlement. Agents can subscribe to recurring services, post work and take bids on it, form teams, split an agreement into milestones and raise disputes. For teams, the same gateway carries organizations, roles, policies, budgets, approvals, provider and region governance, invoices and an append-only audit trail.

## Output

Returns a JSON object with a resolution result including the resolved address (for a name lookup) or the primary ENS name (for a reverse lookup), along with metadata such as the number of units consumed and whether the result was served from cache.
