When To Use This Skill
Use this skill whenever the user asks to: - find data from external APIs - call an endpoint - fetch/search information outside local context - generate an image, video, voice, transcription, or music with an external API - scrape/extract data from a URL - find an API for a task ("is there an API for X?")
If the task needs an external paid API, start with agentspend search.
Playbook (Default Workflow)
npx agentspend search "<task>"- Confirm cost and constraints with the user (
--max-cost, budget, allowlist) npx agentspend pay <endpoint> --method ... --header ... --body ... --max-cost ...
Setup
npx agentspend configure
Opens a URL to add a credit card and set a weekly spending limit. Saves credentials to ~/.agentspend/credentials.json.
If already configured, re-running opens the dashboard to update settings.
Commands
Pay
npx agentspend pay <url>
Make a paid request. AgentSpend handles the payment automatically.
Options:
- --method <method> — HTTP method (default: GET)
- --body <body> — Request body (JSON or text)
- --header <header> — Header in key:value format (repeatable)
- --max-cost <usd> — Maximum acceptable charge in USD (up to 6 decimal places)
Returns: - Response body from the endpoint - Charge amount and remaining weekly budget
Example:
npx agentspend pay <url>
--method POST
--header "key:value"
--body '{"key": "value"}'
--max-cost 0.05
Check
npx agentspend check <url>
Discover an endpoint's price without paying.
Important:
- check must use the same request shape you plan to pay with.
- Always pass --method for non-GET endpoints.
- If the endpoint needs headers/body, include the same --header and --body on check.
- If request shape is wrong, endpoint may return 404/400 instead of 402, and no price can be extracted.
Example:
npx agentspend check <url>
--method POST
--header "content-type:application/json"
--body '{"key":"value"}'
Returns: - Price in USD - Description (if available)
Search
npx agentspend search <keywords>
Keyword search over service names and descriptions in the catalog. Returns up to 5 matching services.
Example:
npx agentspend search "video generation"
Status
npx agentspend status
Show account spending overview.
Returns: - Weekly budget - Amount spent this week - Remaining budget - Recent charges with amounts, domains, and timestamps
Configure
npx agentspend configure
Run onboarding or open the dashboard to update settings (weekly budget, domain allowlist, payment method).
Spending Controls
- Weekly budget — Set during configure. Requests that would exceed the budget are rejected.
- Per-request max cost — Use
--max-costonpayto reject requests above a price threshold. - Domain allowlist — Configurable via the dashboard. Requests to non-allowlisted domains are rejected.
Common Errors
WEEKLY_BUDGET_EXCEEDED— Weekly spending limit reached. Runnpx agentspend configureto increase the budget.DOMAIN_NOT_ALLOWLISTED— The target domain is not in the allowlist. Runnpx agentspend configureto update allowed domains.PRICE_EXCEEDS_MAX— Endpoint price is higher than--max-cost. Increase the value or remove the flag.
