What it does

8-K filings by ticker — the item-coded SEC material-event feed: up to 20 8-Ks a US-listed company filed in 90 days (more → `truncated`), tagged with the SEC's own item codes and titles (1.01 material agreement, 1.05 cybersecurity incident, 3.01 delisting notice, 5.02 officer change). Returns event and filing dates separately, amendments labelled, EDGAR links. Earnings-only filings excluded and counted. Public-domain SEC EDGAR. $0.003 per call.

Use with an agent

Discover. Agents find this listing with GET https://bazaar.saylorinnovations.com/discovery/search?query=…, the MCP tool search_resources, or /discovery/resources.
Inspect. Fetch /resources/25857.json for the price and payment options.
Pay. Call GET https://x402.ottoai.services/8k-material-events. The provider answers 402 with its payment requirements. An x402 client signs one of the options below and retries with PAYMENT-SIGNATURE.
Execute. The provider returns 200 with the data. Agent Bazaar is not in the request path and never sees your payment.

For humans

You don't need an account or an API key; you need a wallet holding a small amount of USDC on Base, Solana, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.
