Attenuate a Macaroon

proof.attenuate
Read-onlyIdempotent

Attenuate an authentic, unexpired L402 parent macaroon by appending restrictive caveats and optionally ttlSeconds. At least one restriction is required. Requires its own L402 authorization; the parent's payment proof remains required for child redemption. Delegation cannot widen authority or reset an inherited quota. Live L402 Satoshi settlement: a configured NWC wallet issues the exact-priced Lightning invoice; paid execution requires confirmed incoming settlement and an invoice-bound payment proof. Handle HTTP 402, pay explicitly, then retry the identical request with Authorization: L402 :. Invoice creation alone is not payment; unavailable verification does not authorize execution.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
caveatsYesList of restriction caveats to append (e.g. ['time_before = 2026-12-31', 'max_target = 870000', 'allowed_tools = stratigraphy.get,stratigraphy.get_digest']). Existing allowed_path and max_requests restrictions are also supported. Constraints: maxItems: 16. Example: ["time_before = 2026-12-31","max_target = 870000","allowed_tools = stratigraphy.get,stratigraphy.get_digest"].
macaroonYesRequired authentic, unexpired parent L402 macaroon (1-8192 characters); caveats and ttlSeconds can only narrow its scope. Constraints: minLength: 1; maxLength: 8192. Example: "base64url-parent-macaroon".
ttlSecondsNoOptional positive integer TTL of 1-2592000 seconds (e.g. 3600); appends an expiration caveat without extending the parent's expiry. Constraints: minimum: 1; maximum: 2592000. Example: 3600.

Output Schema

TableJSON Schema
NameRequiredDescriptionDefault
statusYesSuccessful attenuation status. Example: "attenuated".
issuedAtYesUTC issuance timestamp. Constraints: format: date-time. Example: "2026-09-27T21:00:00.000Z".
appliedCaveatsYesNew canonical caveats appended to the parent; inherited caveats are preserved inside the token. Example: ["max_target=870000"].
attenuatedMacaroonYesEncoded child subscription macaroon. Treat as a bearer credential. Example: "base64url-child-macaroon".
