Analytics differentiators

Endpoints goldprice.dev exposes that Alpha Vantage does not offer at any tier.

Forward view

Futures settlement curve at user-selected expiry dates — gold on every plan including Free, silver and copper on Pro. Gives a structured price expectation grounded in exchange-traded data rather than a single spot quote.

Cross-source divergence

Signed deviation between live oracle spot and futures settlement on the same asset at the same timestamp. Emitted as a flag when deviation exceeds configurable thresholds. Useful for detecting stale upstream feeds or basis widening.

Per-country physical dealer prices

Live dealer sell and buyback quotes with premium-over-spot across 12 countries, on Physical and above — the real price of gold at the counter, not a generic commodity value.

Per-source license disclosure

Add ?include=sources to any price response for a sources[] array naming each upstream feed (live spot oracle, continuous spot reference, futures settlement, ECB reference rates, tokenized gold) with its license terms and source timestamp. Downstream consumers can route attribution or filter sources per their own redistribution rights.

MCP (Model Context Protocol)

Native stdio bridge with eight tools exposing price queries, forward-view fetches, methodology lookups, and source metadata. Available on Free, Physical, and Pro. Used by Claude, Cursor, and custom agents.

FAQ

Is goldprice.dev an alternative to Alpha Vantage for commodity pricing?

Yes, for gold, silver, and copper. goldprice.dev is a commodity-specialist API with live oracle spot, futures settlement, a forward view (futures settlement curve), and cross-source divergence flags. Alpha Vantage is a multi-asset API covering equities, forex, crypto, economic indicators, and commodities; gold, silver, copper, and aluminum are exposed via its commodities endpoint. Pick Alpha Vantage if gold is one asset among stocks + economic data in a multi-asset product. Pick goldprice.dev if metals are the primary use case and per-source transparency, MCP, and forward-view analytics matter.

How do the two quota models compare?

goldprice.dev meters monthly calls at a flat per-tier cap: Free 1,000 calls/month at 30 req/min, Physical 20,000 calls/month at 120 req/min, Pro 100,000 calls/month at 500 req/min. Alpha Vantage meters by rate limit only on paid tiers — no monthly ceiling — from 75 req/min at $49.99/month up to 1200 req/min at $249.99/month. Free on Alpha Vantage is hard-capped at 25 requests/day. For sustained high-volume polling, Alpha Vantage's uncapped paid tiers scale further; for burst or predictable usage under 100K calls/month, goldprice.dev is cheaper.

Does Alpha Vantage cover futures settlement for metals?

Alpha Vantage documents a commodities endpoint with gold, silver, copper, aluminum, WTI, Brent, natural gas, wheat, corn, cotton, sugar, and coffee. The public documentation does not explicitly call out futures settlement symbols (GC, SI, HG) distinct from the spot / generic commodity values. goldprice.dev exposes gold, silver, and copper futures settlement on Pro+ as distinct rows in the sources[] array. If your product resolves against settlement specifically, confirm with Alpha Vantage support before committing.

Which API has MCP (Model Context Protocol) support?

goldprice.dev ships a native MCP server on every plan, including Free. Alpha Vantage has no MCP offering as of 2026-04-25. If you are wiring commodity data into Claude, Cursor, or a custom agent, goldprice.dev exposes eight MCP tools over stdio; Alpha Vantage integrations require REST-wrapper code.

Which API exposes a forward view for metals?

goldprice.dev does; Alpha Vantage does not. goldprice.dev emits a forward-view endpoint covering the futures settlement curve, and a cross-source divergence flag between live spot oracle and futures settlement. Alpha Vantage returns spot commodity values and macroeconomic series without a forward-view or cross-source divergence overlay.

What does the Alpha Vantage free tier look like?

Alpha Vantage Free is capped at 25 API requests per day — roughly 750/month assuming continuous daily use. goldprice.dev Free is 1,000 calls/month at 30 req/min. Both are $0. For the evaluation phase or prototype traffic, goldprice.dev Free offers substantially more headroom plus MCP access.

Which API should I pick for stocks or forex alongside gold?

Alpha Vantage. If your product also needs equity fundamentals, technical indicators on stocks, forex pairs, crypto, or macroeconomic indicators (CPI, Treasury yields, GDP), Alpha Vantage covers all of it under one key. goldprice.dev is metals-specialist; outside gold, silver, and copper it is not the right API.

How is per-source licensing disclosed in each API's responses?

goldprice.dev returns a sources[] array (via ?include=sources) naming each upstream feed (live spot oracle, continuous spot reference, futures settlement, ECB reference rates, tokenized gold) with its license terms and timestamp. Alpha Vantage returns a single value per endpoint call without per-source attribution. If downstream redistribution or compliance requires per-source license disclosure, goldprice.dev exposes that data by default.

Does Alpha Vantage offer per-country gold dealer prices?

No. goldprice.dev Physical ($10+) covers live dealer sell and buyback quotes with premium-over-spot across 12 countries. Alpha Vantage's commodities endpoint returns a generic spot value with no per-country dealer feed.

Who should pick which

Short version: pick Alpha Vantage for multi-asset breadth with uncapped paid volume. Pick goldprice.dev for gold-native depth: per-country dealer prices, forward view, cross-source divergence, and per-source transparency.
