How this service works
Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.
Output
Returns a JSON object containing the SKU identifier ('nportchg'), a title ('N-PORT Change'), the price ($0.40), and associated filing data for the requested fund registrant CIK. Unpaid requests return HTTP 402 with EIP-3009 payment details.
Example use cases

Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/nportchg/%7Bcik%7D?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need N-PORT change filing data for a specific SEC-registered fund and can pay a $0.40 USDC micropayment per call via the x402 protocol with OpenX402 as facilitator. Prefer this over scraping SEC EDGAR directly when you need a structured JSON response gated by a programmable micropayment.
Side effects
- HTTP 402 returned if the x402 micropayment has not been completed — includes EIP-3009 payment challenge in response body
- Invalid or non-existent CIK returns an error or empty result
- CIK must be properly formatted (e.g. 0001350049) — malformed CIK may fail
- Facilitator other than OpenX402 will not be accepted for payment settlement
