PHION Agent Trust Infrastructure

Free complete PHION service index generated from canonical inventory. Use when the agent knows a capability or wants to inspect the full network.

Search the complete canonical PHION inventory by task, capability, protocol or maximum advertised price without selecting or charging.

Retrieve one exact canonical PHION service contract by service id or MCP tool name.

Free service-specific schema, network, budget and economic preflight. It does not execute or charge.

Free provider-neutral capability resolution across eligible payment rails. Applies constraints, preserves UNKNOWN and abstains when evidence is insufficient. Advisory only: never authorizes payment or execution.

Universal PHION execution gateway: enforce a budget and persistent idempotency, execute one selected PHION service, evaluate acceptance criteria, and return a signed completion envelope. No gateway surcharge; the selected service price applies.

Canonical catalog snapshot or digest-based delta with exact HTTP/MCP records, PHION Execute templates and signed evidence; 0.005 USDC.

Free URL safety and reachability check.

Free representative preview, exact price and upgrade instructions for any PHION paid service; no wallet required.

Free, rate-limited payload validation and safe key normalization before payment. Payment-critical values are never changed.

Free diagnosis of the exact payment-funnel stage and machine-readable recovery actions for any PHION service.

Free anonymous non-blocking self-report of wallet, mandate, x402 v2, network, asset, account kind and funding readiness. Detects EVM account types incompatible with exact EIP-3009 before signature. Stores only a daily pseudonymous actor and normalized reason; never a wallet, balance, signature or request content.
