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.
Example use cases
Deterministic user shard assignment
“I need to consistently assign user 'account-7891' to a fixed cell in a 10-wide by 10-tall grid every time — can you run the seeded grid point calculation for that seed and grid size?”
Reproducible A/B test bucket selection
“For my A/B test, map the seed 'experiment-feature-xyz' to a cell in a 4-wide by 5-tall grid so I can bucket it into a deterministic slot.”
Seeded content tile placement
“I want to place a content tile on a 20 by 15 grid using the seed 'campaign-autumn-2024' — which row and column does the seeded grid point calculation give me?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/seeded-grid-point?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
