# Pricing State API — OpenAI API Pricing Snapshot

> Pricing State API — OpenAI API Pricing Snapshot is a paid API for AI agents from pricing-state-api.replit.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-10).

Returns a structured snapshot of OpenAI API pricing including plan names, prices, currency, billing period, and features, fetched on a ~6-hour schedule.

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 pricing-state-api-openai-api-pricing-snapshot-4413aa28
```

Example prompt: What are the current OpenAI API pricing plans, including prices per token or per tier, billing periods, and any listed features — give me a structured snapshot.

## When to prefer this

Choose this endpoint when you need structured, machine-readable OpenAI API pricing data without scraping or parsing HTML yourself. Ideal for agents building cost calculators, monitoring pricing changes, or comparing SaaS vendors programmatically. At $0.01 USDC per call with no API key required, it is well-suited for automated or infrequent polling workflows. Prefer alternatives if you need real-time pricing updates faster than the ~6-hour refresh cadence.

## Known failure modes

- 404 Not Found — if the slug does not exist in the catalog (no charge incurred)
- 503 Service Unavailable — if the monitor has never completed a successful check yet (no charge incurred)
- Payment failure — if the x402 wallet lacks sufficient USDC on Base
- Stale data — snapshot may be up to ~6 hours old if the crawler has not refreshed

## How this service works

$0.01 USDC required (x402 / Base)

Paid 0.01 USDC. Structured snapshot for one catalog slug: plan names, prices, currency, billing period, price text, features when present, snapshot time. Unknown slug returns 404 and a monitor with no first successful check returns 503, both before charge.

No API key needed. Pay with any x402-compatible wallet that holds USDC on Base. If your agent does not yet have a funded wallet, set one up via Coinbase Agentic Wallet or Base MCP — then standard x402 clients will pay and retry automatically.

## Output

A structured JSON snapshot containing OpenAI API plan names, prices, currency, billing period, human-readable price text, features (when available), and the timestamp of when the snapshot was taken. Returns 404 if the slug is unknown, or 503 if no successful check has been recorded yet — both before any charge is applied.
