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 kiteendpoints-ai-tensor-api-142bcddc -d '<json body>'
```

Example prompt: Can you pull the current floor price and recent sales data for a Solana NFT collection using Tensor — I need the marketplace analytics for Mad Lads?

## When to prefer this

Choose this endpoint when you need Solana NFT marketplace data from Tensor without managing your own Tensor API credentials, and you want to pay per request in USDC on Base chain rather than maintaining a subscription. Best for agents that occasionally query Tensor data and prefer micropayment billing.

## Known failure modes

- Insufficient USDC balance causes 402 payment required error
- Malformed or missing Tensor query parameters result in API error
- Tensor upstream service unavailability causes timeout or 503
- Invalid NFT collection address returns empty or error result
- Rate limiting on upstream Tensor API may cause throttled responses

## How this service works

400+ paid API endpoints. Social media, AI, crypto, finance, weather, ecommerce, tools. Pay per request with USDC on Base chain.

## Output

Returns a JSON object with Tensor API response data including NFT collection stats, floor prices, listings, bids, sales history, or other requested marketplace analytics depending on the query sent
