Steps
Request API access/token by submitting the form at sourcengine.com/api-integrations or via your Sourcengine account manager.
Review the developer docs at dev.sourcengine.com/docs for authentication, pagination, and error-handling conventions.
Match/search for the part with POST https://catalog.sourcengine.com/api/parts/search-multiple, body {"searches": [{"mpn": "<MPN>", "manufacturer": "<manufacturer>"}]}, header Authorization: Bearer <access-token>.
From the matched result, take the returned 'sku' and call GET https://catalog.sourcengine.com/api/parts/<sku>/offers/search with the same Authorization header to retrieve current offers.
Iterate the response's priceTiers/quantity/deliveryDays fields per offer to compare supplier pricing and stock.
Watch the RateLimit-Limit/RateLimit-Remaining/RateLimit-Reset response headers and back off on HTTP 429.
Known gotchas
API tokens are not self-service-issued from a dashboard — you must contact your account manager to get one and to adjust your rate-limit quota.
Searching for parts (technical/spec match) and searching for offers (live pricing/stock by SKU) are two distinct calls — a part match does not itself return pricing.
Rate limits are per-endpoint and quota-based per refresh period; bursty requests will trip HTTP 429 well before you'd expect from a flat global limit.
