AveDaris Ephemeral Utility Lease
x402
AveDaris Ephemeral Utility Lease is a paid API for AI agents from api.avedaris.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-28).
Creates a time-limited, invocation-capped capability token that executes a composed sequence of 1–4 approved local AUN utilities on demand, gated by x402 payment settlement.

How this service works
Issue a short-lived capability-token lease for a bounded declarative composition of approved AUN local utilities. $0.02 USDC per call on Base.
Output
Returns a JSON object containing a capability token (returned once, non-replayable), a lease ID, an invoke URL for subsequent calls, the TTL in seconds, the max invocations allowed, an activation status of 'settlement_gated', and an expiry timestamp that populates after settlement.
Example use cases
Disposable pipeline for one-off agent task
“Create me an ephemeral token that runs a base64 encode step followed by a text slugify step — make it good for 10 minutes and allow up to 5 invocations.”
Settlement-gated single-use data transform
“Issue a single-use ephemeral capability that runs a JSON repair step, set the lease to expire after 60 seconds with only 1 allowed invocation.”
Short-lived multi-step utility chain for agent workflow
“I need a temporary invoke URL that chains up to 4 AUN utility steps — slugify, base64 encode, and JSON repair — lasting 30 minutes with a maximum of 10 calls.”
Technical details
Endpoint
POSThttps://api.avedaris.com/v1/paid/ephemeral-utility?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to pre-compose a reusable but temporary pipeline of approved AUN utilities and expose it as a single callable URL with a fixed invocation budget and expiry — particularly useful for delegating a capped execution right to another agent or system without exposing full credentials. Prefer this over direct utility calls when you need settlement-gated access control, a fixed invocation cap, or a short-lived shareable endpoint.
Side effects
- Invalid utilityId references an unapproved or unknown AUN utility — request rejected
- Forward references in step args (referencing a later step's output) — request rejected
- TTL outside 60–3600 seconds range — validation error
- maxInvocations outside 1–10 range — validation error
- More than 4 steps in the plan — validation error
- Payment settlement not received — capability token remains in awaiting_settlement state and invoke URL is not activated
- Capability token already used the maximum number of times — invocation rejected
- Lease expired — invoke URL no longer valid
