Endpoints (2 live)

• POST /api/x402-demand/score — Will anyone pay this x402 endpoint? A calibrated probability (0-1) that a listed x402 resource receives at least one paid call in the next 7 days, from a fine-tuned decision model scored against today's CDP Bazaar catalog, plus the listing's live telemetry and days until eviction. ROC AUC 0.73 on held-out hosts and later dates (0.67 for a LightGBM baseline); top-decile scores were paid 65% of the time, bottom-decile 3%. Send {"resource": "<listed x402 resource URL>"}. Resources not in the current catalog are rejected before payment. Method and free demo: https://sentedge.ai/x402-demand/ (0.01 USDC on Base)
• POST /api/sfx/:id/wav — Master WAV of one verified SentEdge sound effect — 44.1kHz stereo, peak-normalised to -1 dBFS, trimmed and faded, delivered base64 in JSON with its measured acoustics. Every sound is machine-verified: envelope shape matches its declared intent, no clipping, one transient where one was specified. The metadata tells an agent where to align it to a cut (start/peak/end), whether it masks dialogue, and what gain to apply — so it can be placed without listening. Non-exclusive. Free searchable catalogue: GET https://sentedge.ai/api/sfx — filter by name, band, cut-alignment, dialogue-masking, loopability or duration (?q=, ?occupies=, ?align_on=, ?masks_dialogue=, ?loopable=, ?max_duration_s=, ?limit=) instead of pulling all 1000.
