## 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 datastand-dev-llm-pricing-table-2c821421
```

Example prompt: Pull the latest verified LLM pricing table — I want to see input, output, and cached-input costs per million tokens plus context window sizes for all major providers like OpenAI, Anthropic, Google, DeepSeek, and xAI, with the source URLs included.

## When to prefer this

Choose this endpoint when you need structured, citation-backed LLM pricing data across multiple providers in a single call without scraping individual provider documentation pages. It is particularly well-suited for cost comparison workflows, budget planning, invoice reconciliation, or any agent that needs to dynamically select the cheapest model for a task. Prefer this over web scraping when you need machine-readable format with verification timestamps and source URLs. The weekly re-verification cadence makes it reliable for near-real-time pricing but not suitable if you need pricing fresher than ~7 days.

## Known failure modes

- Payment failure (402): USDC payment of $0.05 not processed correctly via x402 protocol
- Stale data risk: pricing data may be up to ~7 days old between weekly re-verification cycles
- Provider not listed: some niche or newly released models may not yet appear in the table
- Network timeout: endpoint unavailable or slow to respond
- Incomplete cached-input pricing: not all providers publish cached input rates, so some rows may have null values for that field

## How this service works

Current LLM API pricing, verified by hand every week: input and output USD per million tokens, cached-input rates where published, and context windows across Anthropic, OpenAI, Google, xAI and Together. Every row is read off the provider's own page on its stated date and carries that URL. A row the provider stops publishing is dropped rather than carried forward, and a context window we could not verify is null rather than guessed. Includes a changes block naming every price that moved.

## Output

A structured table where each row represents a specific LLM model and includes: provider name, model name, input cost per million tokens, output cost per million tokens, cached-input cost per million tokens (where published), context window size, the official source URL for the pricing, and the date the pricing was last verified. Data covers Anthropic, OpenAI, Google, DeepSeek, and xAI. Re-verified weekly by the operator agent.
