Look up one electronic component in the Future Electronics catalog by manufacturer part number (MPN). Returns a compact JSON summary: lookup_value, lookup_results, total_offers (offers found before truncation), and up to max_offers offers. Each offer lists MPN, Future part number, product URL, stock (quantity_available, quantity_on_order), minimum and order multiple, lead time, currency, price breaks, package type, MPQ, RoHS, date code, and datasheet URL when known. When quantity is given, each offer also has price_at_quantity: the price break that applies to that quantity, or a reason there is none (below_minimum, no_pricing, no_matching_break). Pricing matches the Future website and is NOT an official quote: Pricing is not an official quote. Confirm price and availability with Future Electronics before ordering. lookup_type defaults to exact, which matches the full part number. Use starts_with when you know only the beginning of the MPN (for example a base part without its packaging or temperature suffix), and contains when you know a fragment from the middle. Those return more, less precise offers, so check the mpn of each result. Set raw to true only when you need upstream fields the summary omits; it returns the untouched API response (offers still truncated to max_offers) and ignores quantity. Output is compact JSON capped at FUTURE_MAX_OUTPUT_TOKENS: if offers must be dropped to fit, the last ones go and truncated {omitted, hint} says how many. For many parts at once, use future_lookup_parts instead.

Look up many Future Electronics parts at once, e.g. a whole bill of materials (BOM). Accepts up to 2000 part numbers, each optionally with a quantity. Part numbers are trimmed and de-duplicated case-insensitively (quantities of duplicates are summed), then sent in batches of 300, several batches in parallel. Each part is judged on its best offer (the most stock) at the requested quantity (1 when none is given). By default it returns exceptions and totals, not every part: totals (requested, unique, found, not_found, errors, not_attempted, short_stock, below_moq, call_for_leadtime, batches, rate_limited), extended_cost (quantity x applicable unit price, summed per currency), unpriced (found parts with no applicable price break, left out of extended_cost), max_lead_time, and an issues table {columns, rows} listing ONLY problem parts. Problems: short_stock (available < quantity), below_moq (a given quantity < the minimum order), call_for_leadtime (lead time "CALL"), not_found, error, not_attempted; one part can have several, joined by ";" in its reason. Parts with no problem appear only in the counts. detail "all" returns a parts table with a row for every part instead. Output is capped at FUTURE_MAX_OUTPUT_TOKENS: when rows are dropped, truncated {omitted, hint} says so. If one batch fails, its parts get the error and the rest are still returned. If the API rate limit is still hit after retries, the lookup stops early: batches already running finish, and parts in batches not yet started are "not_attempted" (retry them later; totals.rate_limited is true). Prices are not an official quote. Use the single-part lookup tool for full offer details of one part.
