Costo de contexto
Este es el número aproximado de tokens que se consumen cada vez que las herramientas del servidor se cargan en el contexto de un modelo. Los recuentos más altos reducen la atención disponible para otras tareas.

🟢describe_engine
Free. Describe Delta Signal: layers, stings, defaults, limits and prices.

}🟢preview_card(text)
Free. Render the SSTV signature card image for a message (PNG) so you can see what the picture sting will carry.

}🟢render_signature(message, duration, seed, layers, stings)
Render a Delta Signal audio signature (WAV, 48 kHz) that hides your message: in the heartbeat rhythm, as text in the spectrogram, as an inaudible watermark, and optionally as an SSTV picture, a ggwave data chirp or modem tones. Returns a download link (kept 7 days) and a manifest. Survives YouTube-grade AAC/Opus.

}🟢decode_audio(url, seed, layers)
Decode every Delta Signal layer from a WAV, MP3 or M4A (AAC) file at an https URL: heartbeat cipher, spectral glyph, prime count, watermark (needs the seed used to render), ggwave, modem text and SSTV pictures (returned as PNG).

}🟢verify_signature(url, seed, expected_message)
Verify a Delta Signal audio signature at an https WAV URL: returns which hidden layers are present (found_layers) and whether the audio matches an expected message (matches: true/false, or null if no expected_message given). Cheaper than full decode — use it when you only need to confirm presence or identity.
