Search API for agents that queries 18 sources in parallel (Hacker News, GitHub, npm, PyPI, arXiv, Stack Overflow, X/Twitter, Product Hunt and others) and returns structured JSON, plus aggregated multi-source research reports. Paid per call in USDC on Base or Solana, from $0.01.
Pay from $0.01 to $0.50 per request in USDC on Base / Solana, 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/scout-multi-source-intelligence-api/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).
Median across 10 endpoints. Use the selector to isolate one.
Shared payout address (9 other services). These bars are the full shared address (operator-level), so do not sum them across the services that share it. Where a per-service figure is attributed, the assessment block and the ranking, it is the address total divided pro-quota by the 10 services sharing it: a declared convention, not an individually observed measure.
