# Agent402 LLM Model Rates Table

> Agent402 LLM Model Rates Table is a paid API for AI agents from agent402.co.uk, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Returns a static list-price table of LLM model input/output costs in USD per million tokens for use as budget gates in agent workflows.

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 agent402-llm-model-rates-table-6ec58a6f
```

Example prompt: Can you pull the static LLM model rate table so I can check the input and output USD-per-million-token prices before deciding which model to use for this task?

## When to prefer this

Use this endpoint when an agent needs a fast, cheap, deterministic lookup of LLM model prices for budget gating or cost estimation without needing real-time provider quotes. Prefer it over scraping provider pricing pages or maintaining your own rate table. Best suited for pre-flight cost checks inside automated pipelines where sub-cent overhead is acceptable.

## Known failure modes

- HTTP 402 if payment not attached — requires $0.001 USDC via x402 protocol
- Empty or stale data if upstream rate table has not been updated recently
- Prices may not reflect real-time provider changes since this is a static snapshot

## How this service works

Don't burn tokens on deterministic work. Go/no-go jobs first: payout preflight, text firewall (PII/secrets), budget check — then rails, calendars, finmath. x402 USDC on Base. UK + global. agent402.co.uk — not agent402.tools. $0.001–$0.002 USDC on Base. No API keys.

## Output

A JSON array of model objects, each containing the model id (e.g. 'gpt-4o-mini'), the input cost in USD per million tokens, and the output cost in USD per million tokens. These are static list prices, not live provider quotes, suitable for budget estimation and gate logic.
