Steps
Create an LCSC.com account, then submit an API application (company website, business details, contact info, estimated order volume) via the apply form at lcsc.com/agent/apply.
Once approved, obtain your API key/UID and secret from LCSC support.
For every request, build a signature: sha1('key=<key>&nonce=<16-char-random>&secret=<secret>×tamp=<unix-ts>') and send key, nonce, timestamp, signature as request parameters (never send the secret itself).
Call the keyword-search endpoint to look up parts by keyword, or the item-details endpoint for a specific LCSC part number to get the pricing ladder and stock breakdown.
Parse the standard response envelope {success, code, message, result}.
Respect rate limits: 1000 searches/day and 200 searches/minute by default; higher limits require separate approval from LCSC support.
Known gotchas
Requests older than 60 seconds (by timestamp) are rejected — clock skew breaks auth.
Terms of use forbid bulk data capture, re-hosting datasheets/images, reselling the data, or aggregating it into another public API — this is licensed access, not open data.
Full onboarding requires business documentation, so it's not an instant self-serve signup despite being a documented public program.
