## 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 modelprices-xyz-single-model-price-lookup-3abb89d0
```

Example prompt: What does claude-sonnet-5 cost right now — input tokens, output tokens, cache, and batch — in USD per million tokens?

## When to prefer this

Use this endpoint when you need the current price for exactly one known AI model by ID and want the fastest, cheapest single-call answer. Prefer this over the leaderboard or comparison endpoints when you already know which model you're evaluating and just need its cost breakdown for a routing or budgeting decision. The fuzzy matching makes it resilient to minor model ID variations (e.g. 'sonnet-5' vs 'claude-sonnet-5').

## Known failure modes

- Model ID not found — service returns fuzzy-match suggestions or a 404-style error
- Ambiguous model suffix matches multiple models — response may list candidates instead of a single price
- Pricing data temporarily stale — rates may lag a provider's most recent price change
- Payment failure or insufficient USDC balance — call blocked before reaching pricing data
- Malformed model ID in path param — returns 400 or error response

## How this service works

Single-model price lookup: current per-token cost for one AI model by id (e.g. claude-sonnet-5, gpt-5, gemini-3-pro) — input, output, cache and batch USD per 1M tokens. The cheapest way to answer 'what does this model cost right now?' inside a routing or budgeting decision. Fuzzy-matches model ids and suggests alternatives on miss. Includes provenance: provider source URL, first_observed_at, confidence tier.

## Output

Returns a structured object with the model's current USD per-million-token pricing broken down by input, output, cache, and batch dimensions. If the exact model ID is not found, the service fuzzy-matches and may suggest close alternatives.
