How this service works
Execute any selected PHION service with a budget, persistent idempotency, acceptance checks and a signed completion envelope
Output
Returns a signed completion envelope containing the execution result of the selected PHION service, an idempotency receipt confirming deduplication, the outcome of acceptance checks, and a budget usage summary. The envelope is cryptographically signed by PHION for downstream verification.
Example use cases
Budget-capped agentic task dispatch
“Execute the PHION data freshness certificate service for me with a $0.02 budget, make sure it passes acceptance checks, and hand back the signed envelope so I can audit it later.”
Idempotent retry-safe tool invocation
“I need to call the PHION concurrency guard service — use idempotency key 'guard-run-99' so if my agent crashes and retries it won't double-execute, cap spending at $0.01, and return a signed completion receipt.”
Acceptance-gated execution with signed proof
“Dispatch the PHION MCP manifest firewall service, enforce that the acceptance criteria all pass before completing, set the budget to $0.03, and give me a cryptographically signed envelope I can forward to my compliance system.”
Technical details
Endpoint
POSThttps://phion.systems/v1/executeWhen to prefer
Choose this endpoint when you need to invoke any PHION service with guaranteed budget enforcement, idempotent retry safety, acceptance-gated output, and a cryptographically signed completion envelope. Prefer it over calling PHION services directly when auditability, spending limits, or retry-safe orchestration are required. It is the correct entry point when your agent workflow needs a verifiable, tamper-evident record of task completion.
Side effects
- Budget exceeded — service halts execution before completion if the budget cap is reached
- Acceptance check failure — result does not meet specified criteria, envelope is not issued
- Duplicate idempotency key with conflicting parameters — returns conflict error
- Unknown or unavailable PHION service identifier — returns 404 or service-not-found error
- Malformed input schema — returns validation error before execution begins
- Execution timeout — service takes longer than allowed, partial state may be preserved
