Technical details
Endpoint
GEThttps://x402.deepsearch.com/v1/context/us/company/%7Bticker%7DWhen to prefer
Choose this endpoint when you need quick pay-per-query access to US stock price and market cap data without a subscription, especially when integrating with crypto-native payment workflows on Base Mainnet. Prefer it over subscription APIs for low-frequency, ad-hoc lookups of NASDAQ or NYSE stocks by ticker symbol.
Side effects
- Invalid or unrecognized ticker symbol returns an error or empty result
- Exchange parameter mismatch (e.g. NYSE ticker queried as NASDAQ) may return no data
- Payment failure (insufficient USDC on Base Mainnet) blocks the request
- Rate or quota issues may return 402 Payment Required
- Delisted or OTC stocks may not be found in the dataset
