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)

1. npx agentspend search ""
2. Confirm cost and constraints with the user (--max-cost, budget, allowlist)
3. npx agentspend pay --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 — HTTP method (default: GET)
• --body — Request body (JSON or text)
• --header
  — Header in key:value format (repeatable)
• --max-cost — 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-cost on pay to 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. Run npx agentspend configure to increase the budget.
• DOMAIN_NOT_ALLOWLISTED — The target domain is not in the allowlist. Run npx agentspend configure to update allowed domains.
• PRICE_EXCEEDS_MAX — Endpoint price is higher than --max-cost. Increase the value or remove the flag.
