Give your automaton the ability to discover and call any API autonomously.
Semantic API is a universal API discovery service with 160+ indexed providers and 770+ capabilities. This skill lets any Conway automaton search for APIs by natural language, understand their capabilities, and connect to them — all paid via x402 USDC micropayments on Base.
# Via Conway CLI
install_skill(source: "git", url: "https://github.com/peter-j-thompson/semantic-api-skill")
# Or manually
cp SKILL.md ~/.automaton/skills/semantic-api/SKILL.md- "Find me a weather API" → Returns provider config, endpoints, auth requirements
- "I need to send an email" → Matches to SendGrid, Mailgun, Postmark with full specs
- "Analyze this API: https://api.stripe.com" → Deep capability analysis
| Action | Cost |
|---|---|
| Query (find matching API) | $0.01 USDC |
| Search (specific provider) | $0.05 USDC |
| Deep analysis (from URL) | $0.10 USDC |
Payments via x402 protocol on Base mainnet. No API keys needed.
- No charge on errors — If our API fails, you don't pay
- Automatic credits — Server errors give you free retry credits
- Rate limits — 60 req/min per wallet to prevent abuse
