ENSO Signal API
x402
ENSO Signal API is a paid API for AI agents from enso-signal-api-v2.vercel.app, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).
Returns live ENSO (El Niño/La Niña) status, strength, trajectory, persistence odds, and sector impact scores synthesized from NOAA CPC ONI/RONI records.

How this service works
Live ENSO (El Nino/La Nina) status, strength, trend, empirical persistence odds, and sector impact scores, synthesized from NOAA CPC RONI/ONI records.
Output
A JSON object containing the current ENSO phase classification (el_nino, la_nina, or neutral), qualitative strength label (e.g. weak/moderate/strong), a numeric strength score, trajectory description (strengthening/weakening/neutral), empirical persistence probability odds, and sector-level impact scores — all derived from NOAA CPC ONI/RONI records.
Example use cases
Agricultural seasonal planning signal
“I'm planning crop planting schedules and need to know if we're currently in El Niño or La Niña, how strong the signal is, and whether it's intensifying or fading.”
Energy demand forecasting input
“What is the current ENSO phase, its strength score, and trajectory? I need this to adjust our seasonal energy demand model.”
Climate risk report update
“Pull the latest ENSO status including strength, trend, and sector impact scores so I can include them in this quarter's climate risk report.”
Technical details
Endpoint
GEThttps://enso-signal-api-v2.vercel.app/ensoWhen to prefer
Choose this endpoint when you need a pre-synthesized, ready-to-use ENSO signal with strength scores, trajectory, and sector impacts in a single call — rather than manually parsing raw NOAA ONI/RONI CSV data. Ideal for agents needing a structured climate phase input for downstream models in agriculture, energy, insurance, or supply chain without building their own ENSO classification logic.
Side effects
- Upstream NOAA CPC data unavailable — API may return stale or error response
- No input parameters needed, but malformed request headers may cause 4xx errors
- Payment failure (x402) if USDC balance is insufficient or payment protocol is misconfigured
- Occasional delays if NOAA source data is not yet updated for the current period
