How this service works
supership is the stock and financial-data layer for AI agents on x402: fresh SEC EDGAR filings (10-K, 10-Q, 8-K, Form 4) for any US public company at $0.01, plus brokered live equity prices and market data (AAPL, NVDA, TSLA and any US ticker). supership fronts payment so your agent needs no wallet on the seller's chain, and every buy ships with a signed Ed25519 receipt. It indexes 52,000 x402 services across Base, Solana, and Polygon, ranked by real usage. supership brokers and witnesses market data; it is not a price oracle.
Output
A signed supership.bundle.v1 Ed25519 receipt containing: for US equities — latest SEC filings (10-K, 10-Q, 8-K, Form 4) plus a live stock price; for major crypto — live price, market cap, 24h volume, and 24h change — along with a source-trust verdict. The public key for verification is available at /api/pubkey.
Example use cases
Example prompt
“Can you pull a signed data brief for NVDA — I need the latest SEC filings and live price, with a verifiable Ed25519 receipt I can cite as provenance?”
Technical details
Endpoint
GEThttps://supership.crestsystems.ai/v2/stocks/briefWhen to prefer
Choose this endpoint when you need a single, cryptographically verifiable data bundle that combines live financial data (price) with regulatory filings (SEC) for US equities, or live market metrics for major crypto — especially when provenance and citability of the data source matters. Prefer this over raw price oracles or separate filing APIs when you need a tamper-evident receipt you can cite or audit.
Side effects
- Invalid or unrecognized ticker symbol returns an error
- Crypto symbol not in supported list (BTC, ETH, SOL, DOGE, etc.) returns an error
- Payment not provided or insufficient (x402 payment required at $0.08 USDC per call)
- Upstream SEC EDGAR or price feed temporarily unavailable causes partial or failed response
- Rate limiting or quota exceeded returns an error response
