# Delx Commerce — Seeded Grid Point

> Delx Commerce — Seeded Grid Point is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).

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

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-commerce-seeded-grid-point-5c0ece1d -d '<json body>'
```

Example prompt: Using the seed 'launch-2024', compute a deterministic grid point on a 100-wide by 50-tall grid and tell me which row and column I land on.

## When to prefer this

Choose this endpoint when you need a fast, cheap, verifiable, and deterministic mapping from a string seed to a 2D grid coordinate — especially in agent workflows where reproducibility, auditability (via SHA-256 input hash), and no-retention guarantees matter. Prefer it over rolling your own hash-to-grid logic when you want an on-chain-payable, third-party-verifiable result with no signup friction.

## Known failure modes

- Missing or invalid seed string may cause a 400 error
- Non-integer width or height values will fail schema validation
- Seed exceeding 8192 characters will be rejected
- Payment not provided or invalid USDC transaction returns 402 Payment Required
- Server-side error returns 500 with no result

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

Returns a JSON object with 'result' containing 'row' and 'column' integer values representing the deterministically computed grid position, along with a status field ('pass'), operation name, schema version, and an evidence block confirming no data was retained and no external calls were made, plus a SHA-256 hash of the input for verifiability.
