FX Cross Rate Table

Choose this endpoint when you need cross rates between multiple currency pairs simultaneously rather than a single bilateral rate — it avoids making N² individual lookups. Ideal for dashboards, portfolio tools, or trading systems that need a full FX matrix in one call. Prefer it over single-pair rate APIs when comparing 3+ currencies at once.

• Invalid or unsupported currency code returns an error or empty row in the table
• Payment failure via x402 protocol results in a 402 response with no data
• Malformed schema parameter may return an empty or partial response
• Rate data may be stale if the upstream FX feed is delayed
• Unsupported currency combinations may return null rates
