# Delx Seeded Grid Point

> Delx Seeded Grid Point is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-20).

Deterministically maps a seed string to a (row, column) coordinate within a grid of specified width and height

## Facts

- Endpoint: POST https://api.delx.ai/api/v1/x402/seeded-grid-point?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402

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 delx-seeded-grid-point-cd0f72e6 -d '<json body>'
```

Example prompt: Given the seed string 'user-12345', compute which cell it maps to in a 100-wide by 50-tall grid using the seeded grid point calculation.

## When to prefer this

Use this endpoint when you need a fast, deterministic, stateless mapping from a string seed to a 2D grid coordinate — ideal for sharding, bucketing, reproducible placement, or any scenario where the same seed must always yield the same (row, column) pair. Prefer it over custom hash functions when you need a governed, auditable, zero-retention micro-computation with a verifiable evidence trail.

## Known failure modes

- Missing or empty seed string may return an error or undefined behavior
- Width or height values of zero or negative integers may cause computation failure
- Seed exceeding 8192 characters will be rejected
- Malformed JSON body returns a 400-level error
- Payment not included or insufficient USDC results in 402 Payment Required

## How this service works

Seeded Grid Point: Seeded Grid Point selects a reproducible integer coordinate inside rectangular bounds from bounded caller-supplied values without an external provider. Call Seeded Grid Point when an agent needs a reproducible decision that another run can independently replay. Returns the deterministic selection plus seed provenance, population bounds, and the operation-specific outcome for Seeded Grid Point as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First-party, s…

## Output

Returns a JSON object containing a `result` with `row` and `column` integers representing the deterministically computed grid coordinate, along with a `status` of 'pass', the operation name, schema version, and an evidence block confirming no data was retained and no external calls were made.
