Pricing

Amounts are integer micro-dollars (1e6 = $1). No floats.

Kinds

PER_CALL — flat fee per execution.

{ "kind": "PER_CALL", "flatUsdMicro": 3000 }

PER_RESULT — base + per item. Hold uses maxResults / maxItems / limit / count from input (cap 1000).

{ "kind": "PER_RESULT", "flatUsdMicro": 2000, "perResultUsdMicro": 1000 }

PER_UNIT — same math, named unit. Input caps:

unit	fields	hard cap
`result`	`maxResults`, `maxItems`, `limit`, …	1000
`token`	`maxTokens`, `tokens`, `maxOutputTokens`	1e6
`character`	`maxCharacters`, `characters`	1e6
`second`	`maxDuration`, `maxSeconds`, `duration`	3600
`byte`	`maxBytes`	1e9

{ "kind": "PER_UNIT", "unit": "token", "flatUsdMicro": 0, "perUnitUsdMicro": 5 }

Hold — worst-case spend, also capped at remaining wallet / budget / key limit.
Settle — costFor(pricing, billedUnits), never above the hold.
Release — unused hold.

billedUnits: 0 is always free. Provider HTTP >= 400 is not charged. Platform faults are not charged.

A workspace per-run cap blocks (does not silently clamp) when the quoted hold exceeds it.
