agentcash.get_balance()
Returns total USDC balance across supported networks. Use this before paid calls to confirm funds are available.
agentcash.redeem_invite(code="YOUR_CODE")
One-time use per code. Credits added instantly. Run agentcash.get_balance() after to verify.
agentcash.list_accounts() to get per-network wallet addresses and deposit linksImportant: Only Base or Solana network USDC. Other networks or tokens will be lost.
agentcash.discover_api_endpoints(url="https://stableenrich.dev")
Returns all endpoints, pricing, and usage instructions. Read the instructions field — it has critical endpoint-specific guidance.
agentcash.check_endpoint_schema(url="https://stableenrich.dev/api/apollo/people-search")
Returns full request/response JSON schemas and pricing for a specific endpoint.
agentcash.fetch(
url="https://stableenrich.dev/api/apollo/people-search",
method="POST",
body={"person_titles": ["CEO"], "person_locations": ["San Francisco"]}
)
Payment is automatic: sends request, gets 402 challenge, signs USDC payment, retries with credential, returns result. Payments settle only on success (2xx) — failed requests cost nothing.
agentcash.fetch also handles SIWX-authenticated endpoints automatically when the route supports that flow.
