# TensorFeed Benchmark Trust Verdict

> TensorFeed Benchmark Trust Verdict is a paid API for AI agents from tensorfeed.ai, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-13).

Ranks candidate AI models for a given task by cost, speed, quality, or balanced optimization, returning a trust verdict based on live benchmarks and pricing data.

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 tensorfeed-benchmark-trust-verdict-0d918d20
```

Example prompt: I need to pick the best AI model for writing detailed legal summaries — can you pull a TensorFeed benchmark trust verdict ranking models optimized for quality so I know which one to use?

## When to prefer this

Use this endpoint when an AI agent needs to dynamically select the best AI model for a specific task rather than relying on static assumptions. Particularly useful when optimizing for a specific dimension (cost, speed, quality, or balanced) and needing a live, data-backed verdict rather than a cached or manual comparison.

## Known failure modes

- Missing or empty prompt returns a 400 validation error
- Invalid optimize enum value returns a 422 unprocessable entity
- Payment not included or insufficient USDC returns 402 Payment Required
- Service unavailable if upstream model data is stale or unreachable, returning 503
- Empty result set if no models match the task context

## How this service works

TensorFeed is the real-time dashboard for the AI industry. Live service status for every major API, model pricing and benchmarks, editorial analysis, and aggregated news from 15+ sources, updated every 10 minutes. Built for humans and AI agents.

## Output

A ranked list of candidate AI models with a trust verdict indicating which best fits the given task description, scored according to the chosen optimization objective (cost, speed, quality, or balanced), backed by live benchmark and pricing data.
