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 with ok status, an items array containing the current index value (0-100 integer), ISO timestamp, and classification string (e.g. 'Extreme Fear', 'Fear', 'Neutral', 'Greed', 'Extreme Greed'), total count, and source attribution to alternative.me.
Example use cases
Example prompt
“What's the current crypto fear and greed index — is the market in fear or greed right now, and what's the score?”
Technical details
Endpoint
GEThttps://2s.io/api/crypto/fear-greed?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs a real-time, ground-truth numeric sentiment signal for the crypto market without managing API keys or subscriptions. Prefer over scraping alternative.me directly or building your own index aggregation. Ideal for trading bots, market dashboards, or any workflow that needs a single authoritative fear/greed data point on demand.
Side effects
- Data provider (alternative.me) unavailable — upstream fetch failure
- Payment not received — 402 response before data is returned
- Malformed or missing response from upstream source
