Corbits Marketplace

What it does

When your agent uses it

• The user wants to access paid data APIs (crypto prices
• Etc.) with per-request billing and no API key management

Example prompts

• “/corbits-marketplace”

Requirements

• Node.js

Workflow steps

8 steps, taken from the first numbered list in SKILL.md.

1. 1npx clawhub@latest install corbits
2. 2mp wallet create --name "corbits-agent"
3. 3mp buy --token usdc_ethereum --amount 50 --wallet --email
4. 4mp wallet export --wallet "corbits-agent" — copy EVM private key
5. 5/corbits init — paste key when prompted
6. 6/corbits search — discover APIs
7. 7/corbits call — payment auto-deducted from MoonPay wallet
8. 8Top up when needed: mp buy or mp token bridge

What it can do on your machine

Read from SKILL.md and the folder at commit aa672ab. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • npx
  • npm
  • jq

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  Hosts in commands or code, which the agent is likely to contact:

  • api.corbits.dev

  Also links to:

  • corbits.dev
  • npmjs.com

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Corbits Marketplace loads about 1.5k tokens when it runs. Until then it costs about 90 tokens; SKILL.md has 330 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~90

When it runs · the whole SKILL.md, loaded when a task matches

~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description

Paid API marketplace for AI agents via Corbits. Search hundreds of premium API proxies, call them with automatic USDC micropayments (x402 protocol), and fund the payment wallet with MoonPay. Use when the user wants to access paid data APIs (crypto prices, weather, financial data, etc.) with per-request billing and no API key management.

tags

/corbits search <topic>  → find matching API proxies
/corbits list            → browse endpoints + USDC pricing
/corbits call            → select endpoint → review cost → confirm → execute
                           (payment auto-deducted from MoonPay wallet)
