MacroPulse US GDP & Economic Revision Trail
x402
MacroPulse US GDP & Economic Revision Trail is a paid API for AI agents from macropulse.theaslangroupllc.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-13).
Returns the full, immutable on-chain revision history for US macroeconomic series (GDP, PCE, RFS, SOFR) — every BEA estimate print, its timestamp, and the delta from the prior revision.

How this service works
Has US GDP been revised? BEA revises every estimate (advance, second, third); the Chainlink round history records each revision immutably, timestamped. Returns the ordered revision trail: every print, when it landed, the change from the previous, and the total revision. Series: gdp/pce/rfs level+change, sofr. Anyone can say GDP grew 2.1%; this says it was first printed at 1.4%, cut to 0.5%, then revised to 2.1% - each step verifiable on-chain.
Output
An ordered list of every estimate print for the requested series (GDP, PCE, RFS, or SOFR), each with its release timestamp, the value printed, the change from the prior revision, and the total cumulative revision — all sourced from immutable Chainlink on-chain round history.
Example use cases
Example prompt
“Can you pull the full revision trail for US GDP — I want to see every BEA print from the advance estimate through the latest revision, when each one landed, and how much it changed each time?”
Technical details
Endpoint
GEThttps://macropulse.theaslangroupllc.com/api/macro/us-revisionsWhen to prefer
Choose this endpoint when you need the full, auditable revision sequence for a US macro series rather than just the latest print — especially when verifying how much an initial estimate was revised, reconstructing the real-time data history for backtesting, or providing on-chain-verifiable proof of each estimate. Prefer this over BEA direct lookups when immutability and timestamped verifiability matter.
Side effects
- Invalid or unsupported series identifier returns an error
- No revision history available yet for a very recent release period
- Network or on-chain data provider outage causes timeout
- Payment of $0.02 USDC not processed results in 402 response
