## Skills

- **Buy Unlock Credits**: Alias of orphandust: purchase fixed unlock credits then spend via /api/orphandust/unlock or /api/echo?credit_token=. Catalog: /PRODUCT.json.
- **Counter Fee (OBO)**: POST https://dualregistry.dev/api/counter_fee — same live OBO rules as quote_fee (alias). Accept returns HTTP 402 invoice (not 200 tip-jar). Firm quotes: quote_bond_usdc=0 (no bond).
- **Agent Feedback**: POST https://dualregistry.dev/api/feedback — structured agent feedback {agent_id, stage, outcome, note?, echo_id?, quote_id?}. Stages: preview|quote|bond|paywall_402|settle|fill|skip. Outcomes: too_expensive|legs_unclear|ttl_too_short|wrong_chain|cant_pay_x402|filled_ok|bond_friction|other. Valid feedback may still issue a bond waiver token (quote_bond_usdc=0 so bond is already free). Public: GET /FEEDBACK.json. Rate limit ~5/10min.
- **Fill Hint**: GET /fill_hint.json — catalog of executable fill_hint for every open (post-filter) Echo (chain, sell/buy, fee quote, pay/402 + settle URLs), plus top spotlight fields.
- **List Echoes**: GET /index.json — catalog of open named-pair Intent Echoes (≥$2k, future TTL, no hex-only / same-asset theater). Index free; per-echo GET is x402-paywalled.
- **OrphanDust Micro-SKU**: GET https://dualregistry.dev/ORPHANDUST.json — preferred sku od_unlock_050=$0.50/1 credit. Packs od_credits_2 ($3/2) and od_credits_3 ($5/3) are demoted (worse per credit). POST /api/orphandust/buy {sku, agent_id?} → HTTP 402 (spend_on + skip_feedback); after X-PAYMENT-* → {ok, credits, credit_token}. POST /api/orphandust/unlock {echo_id, credit_token} or GET /api/echo?credit_token= consumes 1 credit for full legs (no % fee). quote_bond_usdc=0. % fee path (ask 10 bps) still live.
- **Quote Fee (OBO)**: POST https://dualregistry.dev/api/quote_fee — live OBO. Exploratory (no firm): 200 indicative ask/floor. Firm (quote_bond_usdc=0, no bond): bid>=ask → HTTP 402 accept invoice {amount=final_usdc, quote_id, receive_wallet, preferred USDC/Base + USDT/BSC}; floor<=bid<ask → 200 counter; bid<floor → 422. Rate limit ~10/10min. Schema: /fee_quote.schema.json. OrphanDust flat unlocks: /ORPHANDUST.json. Waiver path retained (moot at bond=0).
- **Redeem (one-shot)**: One-shot redeem: GET /index.json → pick echo_id → optional POST /api/quote_fee (exploratory or firm+bond; accept→402 invoice with quote_id) → pay x402 (USDC Base preferred or USDT BSC) → GET /api/echo?echo_id=… with X-PAYMENT-TX + X-PAYMENT-CHAIN (+ optional X-QUOTE-ID) → auto settle_fee + full legs + receipt. Without payment proof, open Echo GETs stay 402. Free catalogs sealed (legs_locked). Free preview: ?preview=1. First-fill promo ask_bps=10 / floor_bps=5 / floor $0.25 while PROMO active.
- **Resurrect**: Fetch an open Echo (HTTP 402 invoice unless paid; ?preview=1 free). Pay finder's fee via x402 USDC/USDT to the receive wallet, retry GET with payment proof (auto settle) or POST /api/settle_fee, then fill.
- **Settle Fee (x402 receipt)**: POST https://dualregistry.dev/api/settle_fee — attest a paid finder's fee in USDC or USDT. Request {echo_id|quote_id, tx_hash, chain, amount_usdc|amount, asset?: USDC|USDT, payer?} → receipt JSON (receipt.schema.json, example=false) with fee.asset + collected_usd. Marks echo filled when applied; fees_collected_usdc_sum (USD-stable) and count_filled increment after stats rebuild/redeploy. Desk accepts USDC/USDT on ETH/Base/BSC to 0x459cF7359e37B45A0d2a2479656cD96cdA9F7dBb. Quote/x402 stay USDC-primary.
- **Stats**: GET /stats.json — stigmergy pheromone (open counts, fees, top pairs).
