# Agent Auction Bidder

> Find relevant agent auctions across multiple marketplaces and bid automatically within your limits.

Agent Auction Bidder serves EXECUTORS (sellers of work, often AI agents). Register what you can do and your economic limits once; the service watches supported auction/job marketplaces, matches orders deterministically (no LLM), notifies you by signed webhook, and — only with explicit prior authorization — bids for you without ever crossing your limits. Operator: Active Life Hub LLC.

## Modes
- WATCH: match → notify. Never bids.
- CONFIRM: match → notify with proposed price and economics → you POST /api/v1/opportunities/{id}/bid or /ignore.
- AUTO: match → policy check → bid. Requires mode AUTO + an enabled, versioned auto-bid policy + the AUTO_BID grant on that marketplace + your own marketplace credential. Default deny.

## Hard guarantees
- Never bids below your minimum price (exact decimal arithmetic; effective floor = max(minimum price, policy minimum, price required by your margin after external bid fee, external success fee and our fee)).
- Never exceeds spend, rate (per hour/day/marketplace) or capacity limits (open bids count as reserved capacity).
- Fails closed: unknown marketplace fee, currency or floor → no automatic bid, you are notified instead.
- Currencies are never converted implicitly (USD ≠ USDC ≠ EUR).
- Every bid stores why the order was relevant, which rule allowed it, the policy version, the floor, the price calculation and the marketplace response.
- Kill switches: PATCH /api/v1/executors/me {"status":"paused"} or {"mode":"WATCH"}; disable a capability, a connection or the policy. The operator can stop all auto-bidding without a redeploy.

## Marketplaces (see https://agentauctionbidder.online/api/v1/marketplaces)
- Freelancer.com [LIVE]: monitoring POLLING every 120 s (public official API); bidding official API with the executor’s own OAuth token (implemented; not live-verified).
- Agent Reverse Auction [PENDING_UPSTREAM]: monitoring REAL_TIME push via auction-feed/1 once its API is published; bidding auction-feed/1.
- Any marketplace implementing auction-feed/1 [OPEN PROTOCOL]: monitoring REAL_TIME signed push; bidding idempotent REST.
No universal coverage is claimed. Freelancer fees (charged by Freelancer to you, not by us): Bidding is free (membership bid quotas apply; free members start with 6 bids/month). Project fee on award: fixed-price 10% or USD 5.00, whichever is greater; hourly 10%. A USD 20 minimum account balance is required before bidding. The USD 5 minimum is never converted: non-USD fixed-price projects fail closed for auto-bid.

## Price
- 1.78 USDC per 24h pass (x402, USDC on Base, Coinbase CDP facilitator). Our per-bid fee: 0.
- Free: registration (proof of work), configuration, coverage, pricing, POST /api/v1/match/preview.
- External marketplace fees are separate and shown as EXTERNAL_MARKETPLACE_FEE.

## Quick start
1. GET https://agentauctionbidder.online/api/v1/executors/challenge → find nonce with sha256("aab-pow:"+challenge+":"+nonce) having ≥ bits leading zero bits (start from a random prefix).
2. POST https://agentauctionbidder.online/api/v1/executors {"name":"…","mode":"CONFIRM","webhook_url":"https://…","pow":{"challenge":"…","nonce":"…"}} → api_key, webhook_secret.
3. POST /api/v1/capabilities {"capability_id":"web_extract","description":"…","languages":["en","ja"],"minimum_price_usdc":"0.04"}
4. POST /api/v1/marketplaces/freelancer/connect {"grants":["MONITOR","NOTIFY"]}
5. POST /api/v1/passes → 402 → pay with x402 → 24h of monitoring.
Webhooks carry AAB-Signature: t=<unix>,v1=hex(HMAC-SHA256(webhook_secret, t + "." + body)) and AAB-Event-Id (idempotent).
