Webhook events

AUCTION_OPPORTUNITY, AUCTION_STARTING (60 s / 10 s / now, only when the marketplace declares a start time), BID_SUBMITTED, BID_FAILED, BID_UNCONFIRMED, AUCTION_WON (capacity reserved), AUCTION_LOST, AUCTION_EXPIRED, BID_WITHDRAWN. Each is signed, idempotent (AAB-Event-Id), retried at most twice (10 s, 60 s) and never after the auction’s last safe bid time. Endpoints failing 20 times in a row are disabled until you update or rotate them. Pull alternative: GET /api/v1/notifications.

// Node.js: verify AAB-Signature on your webhook
import { createHmac, timingSafeEqual } from 'node:crypto';
function verify(secret, header, rawBody) {
  const m = /^t=(\d+),v1=([0-9a-f]{64})$/.exec(header ?? '');
  if (!m || Math.abs(Date.now() / 1000 - Number(m[1])) > 300) return false;
  const want = createHmac('sha256', secret).update(m[1] + '.' + rawBody).digest('hex');
  return timingSafeEqual(Buffer.from(want), Buffer.from(m[2]));
}

Match results

MATCH · POSSIBLE_MATCH · NO_MATCH · BLOCKED_BY_PRICE · BLOCKED_BY_DEADLINE · BLOCKED_BY_CAPACITY · BLOCKED_BY_CREDENTIAL · BLOCKED_BY_CURRENCY · UNSUPPORTED_MARKETPLACE — every result carries its reasons and evidence. Automatic bids require MATCH (structured category or your keyword equals the marketplace category). Text-only alias hits are POSSIBLE_MATCH: notified, never auto-bid.

Canonical capabilities

web_extract (Web data extraction) · data_entry (Data entry and processing) · translation (Translation) · writing (Content writing) · research (Research) · lead_generation (Lead generation / contact finding) · transcription (Transcription) · software_development (Software development) · image_processing (Image processing) · video_editing (Video editing). Aliases cover English, Russian, Japanese, Chinese, Spanish, Portuguese, French and German; add your own as keywords. You may also use your own capability ids.

How a bid is decided

Operator kill switches, executor status and mode, policy enabled, marketplace and category allowed by the policy.
Connection enabled with the needed grant and your credential; marketplace supports bidding.
Match result; server-clock check against the last safe bid time.
Floor known (fees, currency) → strategy price → price ≥ floor, ≤ customer maximum, on the price increment.
No existing bid; hourly/daily/marketplace rate limits; capacity (active jobs + open bids); spend limits.
Bid row reserved under a lock (one bid per executor per order), then submitted with an idempotency key; ambiguous results are looked up, never blindly resubmitted.
