# HALOWERK creatorwerk > HALOWERK creatorwerk provides machine-readable results paid via x402. > Netz Base Mainnet, Zahlungsmittel USDC, Empfänger 0x2880EdfFF13100677Bf97A3CBdF3Bc34771C4E5E. ## So wird bezahlt 1. Call the route without a payment header. The 402 response includes accepts, description, and inputSchema. 2. Bedingungen mit einem x402-Client signieren. 3. Repeat the call with the proof in the PAYMENT-SIGNATURE header. Eine 402-Antwort kostet nichts und löst keine Arbeit aus. Scheitert die Arbeit, trägt die Antwort charged=false und es wird nicht abgerechnet. ## Endpunkte ### POST /v1/deepfake-score Normalizes caller-supplied blink deviation, lip-sync error, spectral discontinuity, compression inconsistency and metadata anomaly using declared fixed weights. It does not inspect media, establish authenticity, identify a generator or replace human forensic review; the result is only as reliable as the supplied signals. - Preis: 0.003 USDC - MCP-Werkzeug: `creatorwerk_deepfake_score` - Eingabe: `["blink_rate_deviation_fraction","lip_sync_error_ms","spectral_discontinuity_score","compression_inconsistency_score","metadata_anomaly"]` ### POST /v1/watermark-embed Normalizes whitespace, inserts a caller-supplied visible marker after every selected number of words and at the end of a final partial interval, then reports source and output digests. This deliberately visible text annotation is not a robust image, audio or cryptographic watermark and can be removed by editing. - Preis: 0.003 USDC - MCP-Werkzeug: `creatorwerk_watermark_embed` - Eingabe: `["text","watermark_label","interval_words"]` ### POST /v1/royalty-split Requires shares totaling exactly 10,000 basis points, floors each proportional minor-unit allocation, and distributes leftover units by descending fractional remainder with a stable name tie-break. It performs arithmetic only and does not transfer funds, interpret contracts, withhold tax or resolve rights ownership. - Preis: 0.002 USDC - MCP-Werkzeug: `creatorwerk_royalty_split` - Eingabe: `["total_minor_units","currency","recipients"]` ### POST /v1/trend-hijack Tokenizes caller-supplied campaign and trend keywords, calculates overlap relative to the trend vocabulary, and flags any supplied blocked keyword. It neither discovers live trends nor recommends deception, impersonation or spam; its scoped purpose is a transparent relevance and brand-safety screen. - Preis: 0.003 USDC - MCP-Werkzeug: `creatorwerk_trend_hijack` - Eingabe: `["campaign_keywords","blocked_keywords","trends"]` ### POST /v1/plagiarism-music Converts caller-supplied MIDI-note sequences to adjacent pitch intervals, forms fixed-length interval n-gram sets and reports Jaccard overlap. It does not analyze rhythm, harmony, timbre, recordings, access to prior work or legal substantial similarity, and cannot determine plagiarism. - Preis: 0.004 USDC - MCP-Werkzeug: `creatorwerk_plagiarism_music` - Eingabe: `["reference_midi_notes","candidate_midi_notes","interval_ngram_size"]` ### POST /v1/vtuber-rigging Validates frame/channel dimensions, clamps weights to 0–1 and applies exponential smoothing over time in each named channel. It does not infer a face, build a rig, retarget skeletons, process video or replace animator review. - Preis: 0.004 USDC - MCP-Werkzeug: `creatorwerk_vtuber_rigging` - Eingabe: `["channels","frames","smoothing_alpha"]` ### POST /v1/ad-placement-opt Sorts caller-supplied placement opportunities by end time and solves the weighted non-overlapping interval problem exactly with dynamic programming. It does not buy inventory, predict conversion, enforce platform policy, model audience harm or guarantee campaign performance. - Preis: 0.004 USDC - MCP-Werkzeug: `creatorwerk_ad_placement_opt` - Eingabe: `["placements"]` ### POST /v1/fan-engagement Weights likes, comments, shares, saves and clicks, divides by supplied reach, and reports cohort and aggregate points per thousand reached accounts. It does not access a platform, distinguish authentic from manipulated activity, measure sentiment or predict revenue. - Preis: 0.003 USDC - MCP-Werkzeug: `creatorwerk_fan_engagement` - Eingabe: `["cohorts"]` ### POST /v1/thumbnail-ctr Updates one shared beta prior with each variant’s supplied clicks and non-clicks, reports posterior means and bounded normal-approximation 95% intervals, and ranks by posterior mean. It does not run an experiment, correct assignment bias, prove significance or predict future performance under distribution shift. - Preis: 0.003 USDC - MCP-Werkzeug: `creatorwerk_thumbnail_ctr` - Eingabe: `["variants","prior_alpha","prior_beta"]` ### POST /v1/voice-clone-check Calculates cosine similarity between caller-supplied numeric embeddings and combines it with supplied spectral distance, pitch-contour correlation and timing distance using fixed weights. It processes no audio and cannot establish speaker identity, consent, cloning, authenticity or fraud. - Preis: 0.003 USDC - MCP-Werkzeug: `creatorwerk_voice_clone_check` - Eingabe: `["reference_embedding","candidate_embedding","spectral_distance_0_1","pitch_contour_correlation","timing_distance_0_1"]` ## Weitere Flächen - OpenAPI: https://creator.halowerk.com/openapi.json - Preise: https://creator.halowerk.com/pricing - x402-Manifest: https://creator.halowerk.com/.well-known/x402 - Bazaar: https://creator.halowerk.com/.well-known/x402/bazaar - MCP: https://creator.halowerk.com/mcp ## Missing a capability?
