Technical details
Endpoint
POSThttps://cryptoshark-fleet.duckdns.org/worker/sentiment?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a low-cost, per-call sentiment analysis of arbitrary text via a crypto-native payment flow (x402 on Base mainnet), especially within agent pipelines that already handle USDC micropayments. Best suited for single-text classification tasks up to 10,000 characters where a fast turnaround is needed and you want to avoid subscription-based NLP APIs.
Side effects
- Text input exceeds 10,000 character limit — request rejected
- Payment of $0.03 USDC not fulfilled via x402 — 402 Payment Required response
- Empty or missing 'input' field — likely validation error or empty result
- Upstream AI model unavailable — service error response
- Malformed JSON body — request parsing failure
