How this service works
The (most) everything API: 575+ pay-per-call endpoints for AI agents — ground-truth data, a full AI gateway, and agent infrastructure (storage, queues, watchers). USDC via x402, no signup, no API keys, and upto billing: pay actual usage, not the quote.
Output
Returns a JSON object confirming the watcher was created (ok: true), along with an items array containing the watcher record details, an optional total count, and a source object identifying the upstream data provider, URL, and license.
Example use cases
Infrastructure safety alert system
“Register an earthquake watcher for our data center in San Jose at 37.3382° N, 121.8863° W — 200 km radius, minimum magnitude 4.5 — and POST alerts to https://ops.mycompany.com/seismic-alert. Keep it active for 90 days and stop after 100 events.”
Travel safety monitoring for a field team
“Set up a quake watcher around Kathmandu, Nepal (27.7172° N, 85.3240° E) with a 500 km radius for magnitude 4 or greater, fire callbacks to https://safety.myorg.io/nepal-alert, label it 'nepal-field-team', and let it run for 30 days.”
Research pipeline for seismic data collection
“Create an earthquake monitor at -33.8688° S, 151.2093° E covering 400 km around Sydney, triggering on magnitude 3 or above, POSTing to https://research.example.edu/quake-ingest with a payload of {"project":"sydney-seismic-2024"}, and collecting up to 200 events over 45 days.”
Technical details
Endpoint
POSThttps://2s.io/api/watchers/earthquakeWhen to prefer
Choose this endpoint when you need persistent, event-driven earthquake monitoring for a geographic area — rather than one-time historical queries. It is ideal for automated workflows that must react to seismic events in near real-time via webhooks, such as triggering safety protocols, notifying teams, or feeding research pipelines. Prefer it over polling-based approaches when low-latency alerting and long-lived monitoring windows (up to 90 days) are required.
Side effects
- Invalid lat/lon values outside ±90/±180 bounds return a validation error
- callbackUrl that is unreachable or malformed will cause callback delivery failures silently
- expiresInSeconds exceeding 7,776,000 (90 days) is rejected
- minMagnitude or maxFires outside allowed ranges return schema validation errors
- Payment failure or insufficient USDC balance results in a 402 response with no watcher created
- Duplicate or conflicting watchers may consume fire quota without deduplication
