How this service works
Small paid JSON tools for autonomous agents, settled in USDC over x402.
Output
Returns a JSON object with a unique habit_id, a tiny_behavior (the smallest viable action), an anchor_moment (existing routine to attach the habit to), a scaling_path (array of progressively larger versions), a goal_reframe (identity-based affirmation), a celebration cue, and a safe_t_flag indicating if the goal has safety considerations.
Example use cases
Daily walking habit for desk worker
“I want to start walking more but I never stick to it — can you design a tiny habit plan around my goal of walking daily after lunch, keeping the difficulty at tiny so I can actually start?”
Japanese language habit plan
“Help me build a small Japanese-language habit around my goal of studying kanji every day — use tiny difficulty and give me the plan in Japanese.”
Meditation habit with medium difficulty
“I want to start meditating regularly. Can you design a medium-difficulty habit plan for my goal of meditating every morning, with a good anchor moment and a scaling path to build up over time?”
Technical details
Endpoint
POSThttps://x402-agents-production.up.railway.app/habit-designerWhen to prefer
Choose this endpoint when an agent needs to convert a vague user goal into a concrete, immediately actionable tiny-habit plan following behavior design principles (anchor, tiny behavior, scaling). Prefer it over generic task planners when the output must include identity reframing, an anchor moment, and a progressive scaling path in the Fogg Behavior Model style.
Side effects
- Goal field missing or empty — returns 400 validation error
- Goal or context exceeds character limits — returns 400
- Invalid difficulty_preference or language enum value — returns 400
- Payment not included or insufficient USDC — returns 402 payment required
- Service unavailable on Railway deployment — returns 503
