Building a status page for the Bullion API that explains its incidents

I built a public status page for the Bullion API, chose checks with a clear failure meaning, and gave every incident a timeline from open to close.

A public status page that says what each component’s check is
Incidents that open after two failed checks and close after three good ones, each with its own timeline
Email updates for confirmed subscribers when an incident opens or closes
A live status badge on the marketing site and a JSON status endpoint

Requiring a verified email address for Bullion API keys

How I put email verification in front of Bullion API access, then changed sign-up so the emailed link itself proves the address before anyone sets a password.

An API key can’t read price data until its owner verifies their email address
A blocked request gets a 403 with the code email_not_verified, before any quota is used
Sign-up takes only an email address, and the emailed link confirms it before a password is set
A “Verify your email” banner with a resend button in the dashboard

Adding an inflation-adjusted gold price to the Bullion API

I added a gold price in today's money and a gold/real-yield correlation to the Bullion API, and chose seasonally adjusted CPI over a simpler substitute.

Daily gold closes restated in the dollars of the latest CPI month
A public tool that charts the nominal and inflation-adjusted gold price together
Seasonally adjusted CPI from the Bureau of Labor Statistics, so seasonal swings don’t look like gold moving
A rolling correlation between gold returns and the 10-year US real Treasury yield

Adding nine more central banks to the Bullion API's gold data

I added nine central banks to the Bullion API's gold holdings data, and had to make one rule about showing changes hold across every page.

Gold holdings for nine more central banks, from Denmark to Moldova
Central-bank gold pages now cover 52 countries
A weight worked out from a reported value is labelled as a calculation
One rule everywhere: a change the API derives itself is never labelled as buying or selling

Building an MCP server for the Bullion API

I built a read-only MCP server so I could ask an agent about gold without handing it anything that could change an account.

A read-only MCP server at api.bullionapi.dev/mcp, with no write tools
The same data as the REST API, from prices and history to central-bank gold, rates, inflation and your portfolio
Sign in with OAuth 2.1 and approve exactly what an agent may read
A public plugin with two skills, one for market analysis and one for portfolio review

Building a liquidity pool simulator to understand my own DeFi positions

Why I added liquidity pool research and a Uniswap V3 range simulator to Satzo, kept it research only, and moved the liquidation warning earlier.

A liquidity pool research page you can filter by chain, protocol and token pair
A Uniswap V3 range simulator that compares a deposit with holding the two tokens
A public directory of 40 DeFi protocols
Borrowing positions on Aave and Morpho are flagged at a health factor of 1.2, not 1.0

Adding a data page for every dataset in the Bullion API

The Bullion API has more than metal prices. I built a data page that lists every dataset, including the central-bank and rates data that moves gold.

Every dataset in one place: metal prices, countries and economies, production history, gold metrics and calculators
Central-bank gold holdings for 52 countries, with monthly changes back to October 2016
Reserves for 176 countries and regions, with and without gold
Holdings are kept apart from purchases, because a change in holdings often isn’t a purchase

Bullion API1 October

Adding past metal prices to the Bullion API price request

I put past metal prices beside the latest price, so developers can get daily chart data and the latest figure in one request.

Daily prices for the dates you choose from the same request as the latest price
Up to five years of history at a time
One price per weekday, ready to plot; dates without a price are left out

Building one portfolio view for all my crypto wallets

Why I built Satzo's portfolio view to combine every wallet and DeFi position into one total, and why I replaced daily snapshots with transaction replay.

One total across every wallet you add, on Bitcoin, Solana, Ethereum and other supported networks
Aave v3, Pendle, Morpho, Uniswap v3 and Aerodrome positions count towards it
Borrowed amounts count against the total, so it’s closer to net worth
History rebuilt by replaying transactions instead of daily snapshots
