# DataSieve Coordination Workspace

> DataSieve Coordination Workspace is a paid API for AI agents from api.datasieve.xyz, paid per call via x402, $0.25/call, status unknown (last checked 2026-09-15).

Creates a shared multi-agent coordination workspace supporting BARRIER (fan-in synchronization) and LOCK (mutual exclusion) primitives for orchestrating concurrent agent workflows.

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 datasieve-coordination-workspace-986b6f76 -d '<json body>'
```

Example prompt: Set up a coordination workspace for my 5 parallel research sub-agents so that when all of them report back, a single webhook fires to https://my-orchestrator.example.com/done with all their results collected — and if any miss the deadline, send a partial event naming who's missing.

## When to prefer this

Choose this endpoint when you need to fan-in results from multiple parallel sub-agents into a single callback without building your own synchronization infrastructure, or when you need a distributed mutex to ensure exactly one agent performs a critical step. It is especially valuable in agentic pipelines where agents may crash and you cannot afford a permanently blocked workflow — the automatic lease expiry on locks makes it safer than home-rolled locking. Prefer this over ad-hoc polling patterns or external Redis/database locks when you want a lightweight, pay-per-use coordination primitive with webhook delivery.

## Known failure modes

- Missing webhookUrl means caller must poll GET /coord/:id/events for results
- 409 Conflict returned to agents attempting to acquire an already-held lock, naming the current holder
- Partial barrier event fired if one or more sub-agents miss their deadline, listing missing agent IDs
- Workspace expires after 7 days or 1000 operations, after which coordination calls will fail
- Payment failure via x402 prevents workspace creation
- Invalid webhookUrl causes webhook delivery failures silently or with retry exhaustion

## How this service works

Coordinate multiple agents through one shared workspace: $0.25 for 7 days and 1000 operations, all free after this one payment. BARRIER — collect results from N sub-agents: each gets its own arrive URL; when the last one reports, ONE webhook fires with everything collected; a missed deadline sends a partial event naming who's missing. LOCK — exactly one agent performs a critical step: others get 409 naming the holder, and leases expire on their own, so a crashed agent never blocks the rest.

## Output

Returns a workspace ID and configuration including unique arrive URLs for each sub-agent (BARRIER mode) or a lock endpoint (LOCK mode). The workspace is active for 7 days with up to 1000 operations. When the last sub-agent calls its arrive URL, the system fires a single webhook to the provided URL with all collected results. If a deadline passes before all agents report, a partial event is sent naming the missing agents. In LOCK mode, the first agent to acquire the lock proceeds; others receive a 409 with the holder's identity; leases expire automatically so a crashed agent never permanently blocks.
