SYNTHORA Crypto News Sentiment

Data

Pay from $0.001 per request in USDC on Base, settled onchain via the x402 protocol, no signup, no API key needed.

No deterministic risk flag. Risk fires only on an exact blocklist match, or a reserved-brand name with a mismatched verified payTo. Never from low uptime, a high price, or a model guess.

Attributed pro-quota: this payout address is shared, so volume and buyers are the operator-level figure divided by the services sharing it. A declared convention, not an individually observed measure, and still a conservative undercount.

Top buyer share is a concentration signal, not part of the ranking score.

OVER TIME

All charts share the 24h window selected here. Every series is also served as JSON at /api/v1/services/synthora-crypto-news-sentiment/price, /scores, /volume and /buyers. On-chain volume and distinct buyers are measured over the service's settlement address and are a conservative undercount (only settlements that reach a measured facilitator are counted).
