## 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 losbeto-brazilian-official-statistics-revision-trail-3b6b2774
```

Example prompt: Pull the full revision trail for the Brazilian IPCA series — I want to see every correction since first print, how big each revision was in basis points, and when each change was recorded.

## When to prefer this

Choose this endpoint when you need real-time-vintage Brazilian macroeconomic revision data — equivalent to the US Federal Reserve's ALFRED database but for BCB/B3 series — and no public Brazilian equivalent exists. Ideal for quantitative researchers, macro traders, and econometric modelers who need to know not just the current value of a Brazilian statistic but every historical print and correction, with basis-point precision. Not suitable for US, EU, or other non-Brazil macro series.

## Known failure modes

- Missing or invalid 'series' query parameter returns an error
- Unknown or unsupported series identifier returns empty or error response
- Payment failure via x402 (insufficient USDC balance) blocks access
- Network timeout if the series has a very large revision history
- Series with no recorded revisions returns only the first print

## How this service works

OpenAI-compatible LLM gateway at $0.005/call — change base_url, pay in USDC. Plus pay-per-call market data: multi-oracle price consensus, sentiment, forex, equities, commodities, Brazil macro (BCB/B3) and crypto. No API keys, no accounts. USDC on Base, Solana and Algorand via x402.

## Output

A JSON object containing the complete revision trail for the requested Brazilian official statistics series: the first published value, each subsequent correction, the magnitude of each revision expressed in basis points, and the timestamp at which each version was observed by the Losbeto node. This data is unique because it was recorded in real time and cannot be reconstructed retroactively.
