API for AI agents
Developer tools API for AI agents
The best way for an AI agent to use developer utilities is to call a developer tools API per request on Proxygate. Validators, generators, parsers, and converters are callable from one prepaid USDC balance, settled in USDC on Solana, with no subscription and no provider API key to manage. Proxygate injects the upstream key server-side per request.

How AI agents use developer utilities and converters APIs
A coding or automation agent offloads small tasks (validating an email, parsing a cron expression, generating fake data, shortening a URL) to a hosted endpoint and pays per call. Per-request billing means an agent only pays when it actually runs a tool, settling each call from one balance with a signed receipt.

Developer tools API for AI agents: frequently asked questions
On Proxygate there are 50 listings that serve developer utilities and converters, each callable per request by an AI agent. The agent funds one prepaid USDC balance, calls the endpoint through a transparent proxy, and pays only for the calls it makes, settled in USDC on Solana. There is no single "best" provider: an agent can call any of them from the same balance and pick by price, endpoints, and rating.
Your agent authenticates once to Proxygate and never handles the upstream provider key. Proxygate injects the key server-side per request, so the agent just calls the endpoint and the credential is never shared with or exposed to it.
Yes. Every listing here is billed per request, settled in USDC on Solana from one prepaid balance. There is no monthly minimum and no subscription: an agent pays only for the calls it makes, and each call returns a signed receipt.
Pricing is per request and set by each seller, starting from about $0.001 per call, with per-endpoint pricing that can differ from the base rate. An agent settles each call in USDC on Solana with no monthly commitment. See the Developer Tools category for the full range of listings.
