Memory price API

Every level the terminal renders is available over HTTPS as JSON: DRAM, HBM, NAND, LPDDR, NOR, eMMC, SSD and semiconductor contracts, each with its basis flag and source. The board re-prices on a fixed 12-hour clock, so a cached response is never silently stale — the payload carries the session it belongs to.

Authentication

Send your key as a bearer token. x-api-key is accepted as an alternative header. Requests with no key get a free slice: 10 contracts, one session (12 hours) behind, no history.

curl -H "Authorization: Bearer $MEMORYINDEX_KEY" \
  https://memoryindex.io/api/public/v1/prices

Responses carry x-ratelimit-remaining. Over quota returns 429 with retry-after; a lapsed trial or suspended key returns 403.

Endpoints

Endpoint	Returns	Availability
GET /api/public/v1/prices	The whole board for your tier: spot level, 24h / 30d / YoY change, basis flag and source per contract.	All tiers (10-contract free slice without a key)
GET /api/public/v1/prices/{id}	One contract plus its daily close history, depth set by your tier.	History from Professional; Starter returns the level only
GET /api/public/v1/index	MemoryIndex Composite level, 24h / 30d change and per-contract contributions.	Professional and Enterprise

One contract with history

curl -H "Authorization: Bearer $MEMORYINDEX_KEY" \
  https://memoryindex.io/api/public/v1/prices/ddr5-16g-4800

Adds history: an array of { date, close_usd } going back your tier's depth — 365 days on Professional, unlimited on Enterprise.

Composite index

curl -H "Authorization: Bearer $MEMORYINDEX_KEY" \
  https://memoryindex.io/api/public/v1/index

Equal-weighted, rebased to 100 twelve months ago, with each contract's contribution so you can decompose a move rather than take the headline on faith.
