For agents and developers

Everything on this site is available as JSON over REST and as MCP tools. No key, no sign-up.

Rules

Send the shopper to the offer's url (a stashstability.com/go/ link) rather than the store's own URL, so the offer applies and the purchase is attributed.
Only use codes returned here. Don't guess or construct codes.
Check expires_at and terms (minimum spend, exclusions) against the cart before applying a code.
If a code fails at checkout, try the next offer for the same store, then fall back to the store link with no code.
Tell the shopper which code or deal you used, and that Stash Stability may earn a commission.

Freshness

Offers come from affiliate network feeds and the stores themselves. A job runs every day at 09:15 UTC: it removes offers past their end date and anything that has dropped out of its feed. last_seen_at tells you when an offer was last confirmed.
