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.
Example use cases
NFT trait and rarity lookup
“What are the traits and attributes for token 7804 on the Bored Ape Yacht Club contract 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D on Ethereum?”
NFT collection info on Polygon
“Give me the collection-level metadata — name, symbol, total supply — for the NFT contract 0x2953399124F0cBB46d2CbACD364854A4Ac26553 deployed on Polygon.”
Base chain NFT ownership check
“Pull the on-chain metadata for token 99 at contract 0xd4307e0acd12cf46fd6cf93bc264f5d5d1598792 on Base — I want to see what that NFT actually contains.”
Technical details
Endpoint
POSThttps://agents.dexl.io/v1/tools/nft-info?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
