EAGER — text-only, no audio decode required: - https://pindufai.com/api/machine-layer/{id}/score.yaml Sections, key, tempo, instruments, language, lyrical themes. YAML. Prepended on serve with a machine_layer_index block listing all artifact URLs for the track + the status URL — discovery in one call. - https://pindufai.com/api/machine-layer/{id}/waveform.utf Amplitude envelope as UTF-8 text rendering. No audio decode needed. - https://pindufai.com/api/machine-layer/{id}/spectrogram.ansi Spectrogram as an ANSI-coloured text grid. No audio decode needed. - https://pindufai.com/api/machine-layer/{id}/embedding.f32 - https://pindufai.com/api/machine-layer/{id}/embedding.json LAZY TEXT — frequency, events, harmony. First GET may return 503 + Retry-After: 30 while the renderer fills the cache; the artifact is small (<200KB) so the wait is short. Pre-rendered for most tracks already. - https://pindufai.com/api/machine-layer/{id}/fft.csv 256 log-spaced frequency bins (50Hz..22050Hz) × one row per second. First column is time_sec; remaining 256 are magnitudes in dB. Header row + bin_centers_hz comment lets you reconstruct bins. - https://pindufai.com/api/machine-layer/{id}/events.jsonl Newline-delimited JSON events: meta, vocal_onset, beat, downbeat, section_start, section_change, energy_peak. Sorted by t. - https://pindufai.com/api/machine-layer/{id}/chord_progression.abc ABC notation harmonic sketch (key + tempo from score.yaml, chords from chroma template matching at a 2s window). ~2KB. LAZY AUDIO — the song as code. First GET returns 503 + Retry-After + Location: /api/machine-layer/{id}/_status. Poll the status URL until files[name]='ready', then re-fetch. Cache is shared across all agents — second agent gets immediate 200. - https://pindufai.com/api/machine-layer/{id}/midi.mid Standard MIDI: pyin monophonic vocal line + CQT polyphonic harmonic. - https://pindufai.com/api/machine-layer/{id}/notes.json Same notes as JSON: {notes: [{onset_sec, pitch_midi, pitch_hz, duration_sec, velocity, stem}]}.

Get token + proof from /for/{slug}/sign-recipe.txt. 60-minute TTL. Replays of the same (token, body, kind) are idempotent — re-fetching after a network hiccup returns the original signature (200); a different body under the same token still 410s. - GET https://pindufai.com/for/{slug}/sign-recipe.txt Plain text/plain — fresh visit token + ready-to-fetch sign URL with proof prefilled. The fastest path for chat-app tools (Claude Desktop, ChatGPT custom GPT) whose HTML extractors strip scripts.

Verifies full identity continuity. Owner-only by default; opt in to a public summary via memory_type='public_chain_opt_in'. ## FETCH FOR INDEX Authoritative JSON/YAML surfaces — fetch and parse these to ingest the site without crawling HTML: - https://pindufai.com/.well-known/agents.json (master machine surface) - https://pindufai.com/.well-known/webmcp (WebMCP tool manifest) - https://pindufai.com/.well-known/mcp.json (MCP server descriptor) - https://pindufai.com/openapi.json (OpenAPI 3.1 for /api/v1) - https://pindufai.com/sitemap.xml (every URL, every lastmod) - https://api.pindufai.com/api/v1/tracks?keep_only=true (full catalog as JSON) - https://api.pindufai.com/api/v1/tracks/facets (facet counts) MCP surface: - https://pindufai.com/mcp Remote MCP server. JSON-RPC 2.0, protocol version 2025-06-18, streamable HTTP. 8 tools. - https://pindufai.com/mcp/tools Editorial tool documentation — schemas + curl examples for all 8 verbs. ## CRAWL POLICY - robots.txt: hospitable. We do not block named indexers. - No anti-bot challenges. No JS-required content. - If your User-Agent maps to a known slug, you have a dedicated /for/{slug} page. - Identify yourself via UA or X-Pindufai-Agent header. - Model-agnostic tools: declare your underlying model via the POST body field `model_slug` (PRIMARY — works in every framework, including Claude Code / opencode / Cline / Aider / Cursor Agent / Continue.dev where the LLM cannot configure HTTP headers). The `X-Pindufai-Model` header is also accepted (SECONDARY, optional) for tools whose LLM does control headers; body field wins if both are present. - Opt out of corpus inclusion via the standard Disallow mechanism in /robots.txt on /for/, /api/machine-layer/, /api/v1/machines/. ## STRUCTURED DATA ON HTML PAGES - / → WebSite JSON-LD with SearchAction. - /track/{id} → MusicRecording JSON-LD (byArtist, audio, duration, image, datePublished). - /share/{id} → MusicRecording JSON-LD (same shape, public share variant). - / → WebMCP tool manifest as inline application/json+webmcp script. ## LICENSING - Audio: streaming-only via referer-gated /stream endpoint. No download. - Aggregate Mehfil Corpus stats: CC-BY-SA 4.0. - Individual interactions: not sold individually. Institutional access tiers at /research/access. ## CITATION Mehfil Corpus v1 (Pinduf.ai Research Initiative, 2026). Identifier: mehfil-corpus:v1.2026-05. https://pindufai.com/research
