Using Services
1. Pick an origin — or search
Check the Available Services table below first.
If any origin clearly covers the task, skip search entirely and jump to step 2 (discover). Examples:
Task
Origin (skip search)
Look up a person or company
stableenrich.dev
Generate an image or video
stablestudio.dev
Get Instagram/TikTok data
stablesocial.dev
Send an email
stableemail.dev
Upload a file
stableupload.dev
Only use search when none of the listed origins fit:
npx agentcash@latest search
"
Example: npx agentcash@latest discover https://stableenrich.dev Read the output carefully. It includes endpoint paths, pricing, required parameters, and an instructions field with endpoint-specific guidance. 3. Check a specific endpoint before calling it npx agentcash@latest check < endpoint-url
Returns the request and response schema plus pricing guidance. Use this before fetch to avoid 400 errors from wrong field names. 4. Make the request
POST
npx agentcash@latest fetch < url
-m POST -b '{"key": "value"}'
GET
- npx agentcash@latest fetch
- '
?param=value' - fetch
- handles both paid routes and SIWX routes. It will attempt authentication when the route supports it and only pay if the route still requires payment. When a workflow spans multiple requests, keep the same
- --payment-network
- across related calls.
- 5.
- fetch-auth
- is a legacy alias
- npx agentcash@latest fetch-auth
- <
- url
- >
- fetch-auth
- still works, but it is a deprecated alias for
- fetch
- . Prefer
- fetch
- for all new workflows.

Run npx agentcash@latest discover on any origin to see its full endpoint catalog. Important Rules Skip search when a listed origin fits the task. Go straight to discover . Only use search when no origin in the Available Services table matches. Always discover before guessing. Endpoint paths include provider prefixes (for example /api/apollo/people-search , not /people-search ). Read the instructions field. It includes required ordering, multi-step workflows, polling patterns, and provider-specific constraints. Payments settle on success only. Failed requests (non-2xx) do not cost anything. Check balance before expensive operations. Video generation can cost $1-3 per call. Tips Use npx agentcash@latest check when unsure about request or response format. Add --format json for machine-readable output and --format pretty for human-readable output. Base and Solana are both supported payment networks. Use the one called out by the endpoint or the one where the user has funds.
