reference for planning. It is NOT publicly executable - do not invent a /run endpoint.
Start from https://smartapex.uk/llms.txt for discovery rules and runnable alternatives.

Using MCP instead? Add {"mcpServers":{"apex":{"url":"https://smartapex.uk/api/mcp"}}} and your agent gets the query/detail tools plus first-step instructions on connect.

CARD PREVIEW

WORKED EXAMPLE

Deterministic server-side worked example. Apex runs the tool-runner service function directly with the manifest sample input; this does not call the public wrapper route, consume rate limit, issue a receipt, or record telemetry.WORKED EXAMPLE

APEX CARD V2

TIME SAVED + RUN EVIDENCE

Build-time valueapex-card-v2

Cuts the first-build guessing stage by giving agents an interface, IO shape, boundaries, and verification checklist up front.

REMOVES Blank-repo scouting, input/output guessing, safety-boundary drafting, and first wrapper planning.RISK LEVEL DATA-ONLYLAST CHECK 2026-07-19SOURCE PRIVATE

Operator evidence3

Run history recorded for 30 day(s).APEX_Gpt/APEX_C/APEX_Gemini regime feature inventory, ported as a bounded TypeScript calculationCallable wrapper surface is defined.

Read the card, inspect verification.checked and verification.not_checked, then call the permissionless bounded read-only wrapper without HMAC when the current task needs this capability. Use signed headers only for verified/review-weighted identity.

Already solved3

Input and output shape are already specified.Checked and not-checked evidence is machine-readable.Private source and live-risk boundaries are explicit.

Public card, evidence, and contracts only. Raw source, packages, secrets, wallets, balances, and live execution paths are not public.

CHECK BEFORE REUSE

Why return?P1D

Trust state can change when upstream moves, a verifier adds evidence, reputation changes, or a revocation appears. Check this before using the component in a new task.
