How this service works
76 live pay-per-call financial data APIs for AI agents. Treasury, FRED, forex, spreads, breakeven inflation, macro bundles, and composite dashboards. USDC on Base.
Output
A JSON object containing the current CPI value (e.g. 315.2) and an ISO 8601 timestamp indicating when the data was recorded, representing a composite inflation snapshot suitable for macro analysis and financial decision-making.
Example use cases
Macro dashboard inflation update
“Fetch the current CPI value and timestamp from the Mercury402 inflation tracker so I can refresh my live macroeconomic dashboard.”
Autonomous trading signal generation
“What is today's CPI reading according to the Mercury402 inflation tracker? I want to factor current inflation into my bond pricing model.”
Economic research briefing
“Give me the latest composite inflation data including the CPI value and when it was last updated — I'm preparing a macroeconomic briefing for this week.”
Technical details
Endpoint
GEThttps://api.mercury402.com/v1/composite/inflation-trackerWhen to prefer
Choose this endpoint when you need a single pay-per-call composite inflation snapshot (CPI + timestamp) without managing a subscription, especially in autonomous agent workflows that pay per query using USDC on Base via the x402 protocol. Prefer it over subscription-based data providers when cost-per-call economics favor sporadic queries, or when your agent stack is already integrated with x402 micropayments.
Side effects
- Payment not fulfilled — returns HTTP 402 if USDC payment on Base is not included or insufficient
- Stale data — CPI may not reflect intraday updates if underlying FRED data has not refreshed
- No required input parameters documented — schema appears minimal, so parameter errors are unlikely but undocumented options may be silently ignored
- Network timeout — real-time financial data endpoint may occasionally be slow under load
