# DexL Agents NFT Info

> DexL Agents NFT Info is a paid API for AI agents from agents.dexl.io, paid per call via x402, $0.006/call, status unknown (last checked 2026-10-12).

Fetches on-chain NFT collection metadata and optionally per-token metadata for a given contract address on any of 28 supported EVM chains.

## 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-agents-nft-info-ef950a62 -d '<json body>'
```

Example prompt: Can you look up the metadata for token ID 1234 on the NFT contract 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D on Ethereum?

## When to prefer this

Choose this endpoint when you need no-account, pay-per-call NFT metadata retrieval across a wide range of EVM chains (28 supported) without managing API keys or RPC endpoints. Particularly useful for AI agents operating autonomously with x402 micropayment capability. Prefer it over chain-specific NFT APIs when multi-chain coverage or zero-setup access is a priority.

## Known failure modes

- Invalid or non-existent contract address returns empty or error output
- Unsupported chain identifier causes a validation error
- Token ID not found on the contract returns empty token metadata
- Network or RPC issues on the target chain may cause timeouts
- Malformed 0x address rejected at input validation

## 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 containing NFT collection metadata and, if a token ID was supplied, the per-token metadata including name, description, image URI, and attributes. The response includes a cache indicator and a units field reflecting billing.
