## 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 br-data-api-ipca-rate-c059fc0c
```

Example prompt: What is Brazil's current IPCA inflation rate and the 12-month accumulated figure? Fetch the latest available data.

## When to prefer this

Choose this endpoint when you need clean, normalized IPCA inflation data for Brazil without building your own BCB scraper, require no signup or API key (pay-per-call via x402 USDC), and need the data programmatically in a structured JSON format suitable for agent workflows, financial calculations, or automated reports.

## Known failure modes

- 402 Payment Required – USDC micropayment via x402 not completed or insufficient funds
- 429 Too Many Requests – rate limit exceeded
- Invalid months parameter – value outside 1–60 integer range returns a validation error
- Service unavailable – upstream BCB/IBGE data source temporarily unreachable
- No data available – reference period not yet published by the statistical authority

## How this service works

Clean, normalized Brazilian public data (CNPJ, CEP, BCB rates, PTAX, holidays/business days, banks/ISPB) for AI agents. Paid endpoints use x402 (HTTP 402, USDC) — no signup or API key. Not affiliated with Receita Federal, Banco Central or Correios.

## Output

A JSON object with two top-level fields: `latest_month` (the most recent monthly IPCA value in percent and its reference period in YYYY-MM format) and `accumulated_12m` (the 12-month accumulated IPCA rate and its reference period). Example: latest_month -0.32% for 2026-08, accumulated_12m 4.22% for 2026-08.
