How this service works
Give a goal and the actions available to you; get back the single best action, its arguments, a confidence and a reason. The chosen action is constrained by schema enum to your list, so it can never name a tool you do not have. Built for the decision an agent makes before spending a frontier-model call — including the honest answer that it should escalate. Priced per call. For high-volume use, buy prepaid credits (POST /x402/credits/buy) and send X-Animica-Credits on each request — no settlement, no gas, no per-call payment round trip. Paying in ANM on the animica:1 lane is also ~25% cheaper because we sponsor no gas there.
Output
A JSON object containing: the name of the selected action, the arguments to pass to it, a confidence score (0–1), a natural-language reason explaining the choice, a boolean escalate flag indicating whether the agent should hand off to a human, and the name of the model that made the decision.
Example use cases
Agentic task planner for customer support bot
“My support agent has the goal 'resolve user refund request' and can perform these 4 actions: lookup_order, verify_eligibility, initiate_refund, send_email — with their descriptions. Which action should it take first and what arguments should it pass?”
Multi-step coding assistant action routing
“My coding agent is trying to 'fix a failing unit test' and has access to these actions: read_file, run_tests, edit_file, commit_changes — all described with their parameters. Tell me which action to call next, the arguments, your confidence, and your reasoning.”
E-commerce agent next-step decision
“My shopping agent's goal is 'complete the user's checkout' and the available actions are: get_cart, apply_coupon, charge_card, send_receipt. Given that the cart has already been fetched, which action should it take next and with what arguments?”

Endpoint
POSThttps://animica.dev/x402/routeWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call AI decision layer that selects among 2–20 discrete actions for an agentic workflow — especially when you don't want to manage your own LLM API key, need a fast action-routing step with confidence scoring and escalation signals, and want to pay only per inference via x402/USDC. Prefer alternatives if you need to generate free-form text, stream responses, or require a specific model provider.
Side effects
- Missing required 'goal' field returns a 400-style error
- Fewer than 2 or more than 20 actions in the actions array may be rejected
- Malformed action objects without a name or description may cause low-confidence or error responses
- Payment failure (402) if the x402 USDC payment of ~$0.005452 is not included or rejected
- Ambiguous goal/context may result in low confidence scores or escalate=true
- Model unavailability on Animica's backend could cause 5xx errors
