## Facts

- Price: $0.002/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14

- Tags: x402
- Canonical page: https://www.zero.xyz/c/bank-of-canada-fx-rates-boc-valet-54af0fd0

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 bank-of-canada-fx-rates-boc-valet-54af0fd0
```

Example prompt: What's the official Bank of Canada USD/CAD exchange rate for the last 5 days? Use the BOC Valet data and give me the daily observations.

## When to prefer this

Use this endpoint when you need official, authoritative Bank of Canada daily FX rates (not real-time tick data), especially for CAD-denominated currency pairs. Prefer this over commercial FX APIs when regulatory or audit-grade sourcing from a central bank is required, or when cost is a concern ($0.002/call). Ideal for batch historical lookups of up to 60 days and up to 10 series per call.

## Known failure modes

- Invalid series code returns empty or error response
- Requesting more than 10 series at once may be rejected
- Recent parameter outside 1-60 range may return error
- HTTP 402 returned if payment not provided — must pay $0.002 USDC via x402 on Base before data is returned
- No data returned for weekends/holidays when BOC does not publish rates

## How this service works

Official Bank of Canada Valet observations, normalized JSON. Query: ?series=FXUSDCAD,FXEURCAD&recent=5 (1-10 comma-separated codes; FX pairs like FXUSDCAD/FXEURCAD/FXGBPCAD, overnight target rate V39079, prime rate V80691311). recent=N returns the last N daily observations (default 1, max 60). Primary-source CAD reference, published each business day; 6h cache.

## Output

A JSON object containing labeled exchange rate series (e.g. FXUSDCAD) with an array of date/value observation pairs and a source attribution to the Bank of Canada Valet API.
