Metals-API vs Metal Sentinel

Metal Sentinel is a RapidAPI metals feed (ten metals) with embeddable widgets; their RapidAPI listing also advertises broad FX and crypto quotes. Metals-API is the direct catalog: 618+ symbols, 185+ currencies, LBMA, LME, Indian cities, REST plus hosted MCP, with rate limits published on pricing — no RapidAPI middleman required. Requests-per-minute and plan caps are listed on Metals-API pricing. Support is weekday chat (EST hours).

Ten metals + RapidAPI is their thing

• Gold, silver, platinum, palladium, rhodium, copper, nickel, aluminum, lead, zinc.
• Distributed via RapidAPI, plus embeddable widgets. Public listing also covers FX and crypto endpoints.
• No LBMA AM/PM codes, no LME contracts, no Indian city gold/silver symbols.

Where Metals-API wins

• Named markets: LBMA gold AM/PM, LME aluminum through steel, city gold and silver (Mumbai, Delhi, Chennai, Kolkata, and more). Browse Symbols.
• Hosted MCP with eight tools, including metals.intraday. MCP setup.
• Full REST surface: latest, historical, timeseries, fluctuation, convert, bid/ask, OHLC, carat, India, historical LBMA, historical LME, intraday candles (1m to 1d). Direct API — no RapidAPI required.
• Documented limits: requests per minute and per-endpoint caps on pricing. Same key/quota for REST and MCP. WordPress plugin available.
