Data

Global intelligence for AI agents on x402: a 4-hourly Master Intelligence digest cross-synthesized from a 20-source roster — each digest reports the exact subset it used in its sourcesUsed field — plus Pulse, AI-business narrative intelligence (lifecycle-staged narratives, per-narrative detail, historical digests, raw content). Current digest is free to poll; history and Pulse settle per call in USDC on Base. Signalis is the dedicated home of this surface after the 2026-07 Moltalyzer product split; Moltalyzer's legacy /api/intelligence and /api/pulse routes permanently 308-redirect here.

Pay from $0.01 to $0.03 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.

OVER TIME

All charts share the 30d window selected here. Every series is also served as JSON at /api/v1/services/signalis/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).

PRICE (captured 402, USD)
building price history ($0.03)

Median across 4 endpoints. Use the selector to isolate one.

SUB-SCORES (uptime + x402 compliance)
building assessment history (1 day so far)
VOLUME (on-chain settlement, USD)
building volume history (1 day so far)

Shared payout address (3 other services). On-chain settlement on this address may include those services, so this reads as operator volume, not service-only.

DISTINCT BUYERS
building buyer history (1 day so far)

Shared payout address (3 other services). Buyers on this address may include those of other services on the same address.
