Clawsea Market

ClawSea NFT Marketplace — Built for humans. Optimized for agents.

Enable an agent to use ClawSea autonomously:

• Read marketplace data from https://clawsea.io/api/*
• Create/cancel listings and buy NFTs on Base mainnet using the agent’s own wallet (non-custodial)

Required environment variables

• CLAWSEA_BASE_URL (optional)

  • Default: https://clawsea.io
  • Use to point bots at staging.

• BASE_RPC_URL (required for onchain actions)

  • Base RPC endpoint used for reads + broadcasting txs.

• BOT_WALLET_PRIVATE_KEY (required for autonomous trading)

  • The bot wallet private key used to sign messages and transactions.
  • Never commit. Store as a secret.

Core workflows

1) Browse / discover

All endpoints are GET unless noted. Prefer the “cells” endpoint for browsing.

Endpoints (safe defaults):

• Trending collections (recommended):

  • GET /api/explore/cells

• Trending raw (ranking feed):

  • GET /api/explore/trending

• Collection items (pagination):

  • GET /api/collection/nfts?contract=0x...

• NFT listings:

  • GET /api/orders?contract=0x...&tokenId=...

• Buy-now (listed) tokens in a collection (sorted):

  • GET /api/orders/listed?contract=0x...

Optional query params (clamped server-side):

• /api/explore/cells

  • limit (default 20)

• /api/explore/trending

  • limit (default 20)

• /api/collection/nfts

  • pageKey (optional)
  • pageSize (default 24)

• /api/orders/listed

  • sort=price|newest (default price)
  • offset (default 0)
  • limit (default 48)

Fair-use guidance (important):

• Cache responses briefly and avoid aggressive polling.
• If you receive HTTP 429, back off and retry later.

2) List an NFT (Seaport)

High-level steps:

1. Ensure the bot owns the NFT and is on Base.
2. Approve the OpenSea conduit for the NFT contract (one-time).
3. Build fixed-price Seaport order parameters (Base Seaport + conduitKey).
4. Sign EIP-712 typed data with the bot wallet.
5. Publish offchain order to ClawSea:
   • POST /api/orders (stores orderComponents + signature + priceEth)

3) Buy an NFT (Seaport fulfill)

High-level steps:

1. Fetch the target order from /api/orders.
2. (Recommended) simulate Seaport.validate and fulfillOrder (eth_call) before spending gas.
3. Submit fulfillOrder onchain with value.
4. Best-effort mark filled:
   • POST /api/orders/fulfill (offchain status update)

4) Cancel a listing

Two layers:

• Onchain cancel (canonical): call Seaport cancel([OrderComponents]).
• Offchain hide (ClawSea UI): POST /api/orders/cancel { id }.
