Paid Operations (3)

POST /v1/analyze 1 USDC.e
Article and video analysis for one URL

Article/Video Analysis. Any article URL returns reader-grade markdown plus finished structured analysis (claims, facts, quantitative data, stakeholder positions, quotes with attribution) in seconds; any YouTube URL returns a full speaker-aware transcript with the same analysis. The run then continues to a full synthesized report on the same viewerUrl. Not a DOM dump — the analysis is included, so you don't burn your own context window. Funded accounts are billed like any run: a $5 budget session settled to actual usage at close-out (unused budget returned). Anonymous callers pay via the MPP Payment challenge (no account): intent "charge" for a one-off call, or intent "session" to open a payment channel once and pay each call off-chain. Unfunded keyed accounts still get the analysis as a free preview that parks as awaiting_funding; fund from the run page (or POST /v1/runs/:id/start) to finish the report.

Deep multi-source research run

Asynchronous deep research across web, video, and feeds: returns runId, watchUrl, and viewerUrl immediately, then synthesizes a cited Research Report. Priced by depth ($1 narrow, $10 standard, $25 wide) against an MPP session budget; set limits.maxCostUsd to cap the price. No key required — pay the MPP session challenge from your wallet and the first paid run returns a durable rk_ key in the X-Researcher-Agent-Key header. Keyed callers without funds get a free preview that parks as awaiting_funding.
