Coord Workspace

by DataSieve in Onchain & crypto

x402 APIPassing, checked 3 h ago

One shared workspace for a fleet of agents: $0.25 for 7 days and 1000 ops, every op free after this one payment. BARRIER: N sub-agents each get an arrive URL; the last arrival fires ONE webhook carrying every result, a missed deadline names who never showed. LOCK: leases that expire, so a crash cannot deadlock the fleet. KEYS: checkpoints a dead run resumes from. MAILBOX: a post-only URL safe to publish — in a web form, or handed to one sub-agent — that can only append to that one mailbox.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.25.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://api.datasieve.xyz/coord/workspace' \
  -H 'content-type: application/json' \
  --data-raw '{}'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - -X POST 'https://api.datasieve.xyz/coord/workspace' \
  -H 'content-type: application/json' \
  --data-raw '{}' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
