# Batch Rate Limit Plan

> Batch Rate Limit Plan is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-17).

Calculates dispatch duration and rate window parameters from a request count, limit, and window size, returning a bounded, versioned deterministic result.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability batch-rate-limit-plan-4fcc61e9 -d '<json body>'
```

Example prompt: Figure out the dispatch timing for a batch of 500 requests where the rate limit is 100 per window and the window is 60 seconds.

## When to prefer this

Use this endpoint when an agent needs to pre-compute safe batch dispatch timing before handing a batch plan to a rate-limited downstream tool. It is ideal for deterministic, in-memory calculations that require no external provider — prefer it over ad-hoc arithmetic when a versioned, auditable result contract is needed for downstream validation.

## Known failure modes

- Missing required fields (limit, request_count, or window_seconds) result in a validation error
- Non-integer or negative values for any input field cause a bounds error
- Zero window_seconds causes a division error or invalid plan response
- Extremely large input values may be clamped or rejected based on internal bounds

## How this service works

Batch Rate Limit Plan: Batch Rate Limit Plan calculates dispatch duration from request count and rate window from bounded caller-supplied values without an external provider. Call Batch Rate Limit Plan before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for Batch Rate Limit Plan as versioned deterministic JSON. Price: $0.001 US…

## Output

Returns a versioned deterministic JSON object containing computed dispatch duration, normalized request counts, rate window parameters, and a versioned result contract confirming the bounded calculation.
