## 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-ai-161869f9
```

Example prompt: Pull the fact card for anthropic/claude-haiku-4.5 from OpenRouter — I want to see normalized pricing in USD per million tokens, the blended 5-to-1 mix cost, and whether it supports tools, vision, structured outputs, and reasoning.

## When to prefer this

Use this endpoint when you need a single, clean, normalized fact card for one specific OpenRouter model — especially when you need pricing in a consistent USD-per-million-tokens format with blended mix and capability flags. Prefer this over scraping OpenRouter directly or using a bulk catalog call when you only need one model's details.

## Known failure modes

- Model ID not found in OpenRouter catalog — 404 or empty response
- Model ID contains slash and was not URL-encoded — malformed URL or wrong model returned
- Payment of $0.02 USDC not completed — 402 Payment Required
- OpenRouter catalog not refreshed yet for the day — stale or missing data
- Invalid or malformed model ID — error response

## How this service works

One model from the daily 367-entry OpenRouter catalog as an LLM-ready fact card. Pricing normalized to USD per million tokens with a derived blended_5_to_1 mix. Capability flags (tools, vision, structured_outputs, reasoning) extracted from supported_parameters plus modality. Pass the model id (URL-encoded if it contains a slash) as the URL path segment.

## Output

A structured JSON fact card for the requested model containing: normalized USD-per-million-token pricing, a derived blended_5_to_1 pricing mix, and boolean capability flags for tools, vision, structured_outputs, and reasoning, extracted from the live OpenRouter catalog entry.
