estimate_cost

Read-onlyIdempotent

Estimate audio analysis cost anonymously and free before committing. Read analysis_options for eligible anonymous one-off Checkout, trial duration fit and key-based banked-token use; these do not verify balance or trial entitlement. Eligible quotes can include checkout.upfront_payment_estimate from the current charge builder; this is not a reserved price or a saved-link charge. Review the hosted amount before payment. Returns estimated dollars, job_estimate_id and expires_at. Review the estimate before spending; final cost depends on measured duration and completed analysis, and Checkout can collect a buffered amount with refund thresholds. If processing or payment returns estimate_pricing_changed, get a fresh free estimate, present the new price, and wait for explicit user approval before processing or payment. Never silently retry analysis or purchase.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`tools`	Yes	Analysis tools to price. Available in v1.0: bpm, key, waveform. Coming soon: structure, chords.
`audio_url`	Yes	Publicly accessible URL of the audio file (MP3, WAV, FLAC, OGG, Opus).

Output Schema

TableJSON Schema

Name	Required	Description
`note`	No
`error`	No	Machine-readable error code.
`tokens`	No	Estimated Pulse tokens.
`details`	No	Additional structured context from Pulse.
`message`	No	Human-readable recovery guidance.
`cost_usd`	No	Estimated analysis cost in USD.
`breakdown`	No	Per-tool token and cost estimate.
`retryable`	No	Whether the caller may retry after changing state or waiting.
`expires_at`	No	ISO timestamp when the estimate expires.
`content_type`	No
`cost_display`	No	Human-readable USD estimate.
`duration_source`	No	Duration provenance: prior worker measurement, declared WAV or MP3 frame metadata, MP3 bitrate inferred from a bounded prefix, assumed format byte rate, or placeholder. Prefix bitrate cannot establish that the whole file is constant bitrate. All quotes remain estimates; processing measures actual audio.
`job_estimate_id`	No	Estimate identifier valid for the configured TTL.
`analysis_options`	No	Advisory continuation choices for this estimate, not a reserved charge, verified balance, trial grant or host certification.
`normalize_source`	No
`duration_inferred`	No
`audio_url_original`	No
`audio_url_normalized`	No
`content_length_bytes`	No
`duration_estimate_sec`	No	Estimated audio duration in seconds.
