Technical details
Endpoint
GEThttps://x402.professorsausages.com/insider-trades/insider/:cik?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to track a specific individual or entity (serial founder, activist investor, fund principal) across all companies they have filed Form 4 reports for, rather than looking up insiders by issuer. Ideal for profiling a single insider's cross-company trading behavior rather than all insiders at one company.
Side effects
- Invalid or non-existent CIK returns a 404 or empty result set
- CIK belongs to an issuer rather than a reporting owner — no Form 4 data returned
- Reporting owner has no Form 4 filings on record — empty response
- Rate limiting or payment failure results in 402 response
- EDGAR data lag may mean very recent filings are not yet reflected
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| chainrequired | string | Which chain the address belongs to. base and ethereum run full on-chain mode; the rest are list-only mode. |
| addressrequired | string | The address in that chain's native format (0x… for EVM, base58/bech32 otherwise). Checked against that chain's shape BEFORE the payment gate — a malformed address is a free 400, never a 402. |
