Delx Commerce — Seeded Round Robin Start
x402
Delx Commerce — Seeded Round Robin Start 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 selects a starting index for round-robin distribution given a seed string and a member count, with verifiable no-retention processing.

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 containing a `start_index` (the deterministically computed starting position within the round-robin) and `member_count` (echoed back), along with a verifiable evidence block including an input SHA-256 hash, confirmation that no data was retained, and a count of zero external calls made during processing.
Example use cases
Agent fleet task distribution
“I have 12 worker agents and want to distribute incoming jobs fairly. Use the seed 'job-batch-2024-06' and 12 members to get the starting index for a seeded round robin so each batch starts from a different agent.”
Reproducible team rotation scheduling
“We rotate on-call duty across 5 engineers each week. Use the seed 'oncall-week-42' and member count 5 to deterministically pick which engineer starts the rotation this week.”
Consistent shard assignment for requests
“I need to assign requests consistently to one of 8 shards without randomness. Compute the seeded round-robin start using seed 'tenant-xyz-2024' and 8 members so I get the same result every time for that tenant.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/seeded-round-robin-start?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, reproducible starting index for round-robin task or resource distribution — especially when auditability and verifiable no-retention processing matter. It is ideal for AI agent orchestration scenarios where you need consistent, seed-driven assignment without storing inputs. Prefer it over custom hashing logic when you need cryptographic evidence (SHA-256 of input) confirming the computation was clean.
Side effects
- Missing required fields (seed or member_count) result in a validation error
- member_count of zero or negative may cause a divide-by-zero or invalid range error
- Seed strings exceeding 8192 characters will be rejected
- Payment failure via x402 results in a 402 response before computation occurs
- Malformed JSON body returns a 400 bad request
