How much to trust it, right now
A freshness score and a confidence score ship with every number, so you always know how current and certain it is, not just what it is.

}Built for AI agents
Your agent can just ask.
Connect Claude, an IDE, or any agent framework with one command, and it can pull live prices, option chains, and scores on its own, sources included, automatically.

}BTC-USD is trading around the reference price above (98% confidence, sourced from Binance + Coinbase). For downside protection: the Jul-31 put shown above is quoting around its mark price (44% IV, delta −0.48) on Deribit.
- Token-budgetedEvery tool takes max_response_tokens, truncates to whole rows (never mid-object), and returns meta.truncated + meta.next_cursor + a one-line hint.
- Provenance inlineEvery envelope carries the exact venues, timestamps, and method behind the number, no separate lookup needed to decide whether to trust it.
- RFC 9457 errorsFailures come back as application/problem+json with retryable, retry_after, and error_category: an agent can branch on a failure in code, not by parsing prose.
- Honest tool contractsEnum'd args, readOnlyHint / idempotentHint / openWorldHint annotations, and outputSchema: the host can show what a tool will do before it's called.
