x402
Coding Agent Context APIs – Gateway Run is a paid API for AI agents from x402-canary.nicolas-x402-16f380a7.workers.dev, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-15).
Routes coding-agent utility requests to tools like exchange rates, FX conversion, cron explanation, DNS lookup, URL normalization, domain enrichment, email preflight, JSON inspection, and SHA-256 hashing via a single gateway endpoint.

How this service works
Free need-to-tool routing plus pay-per-call npm docs and TypeScript API signatures, npm breaking-change diffs, JavaScript-rendered browser snapshots and deterministic coding-agent checks via AgentCash/x402.
Output
A JSON object with a 'data' field containing the tool name and its result (e.g. cron schedule breakdown, exchange rate, DNS records, normalized URL, domain metadata, SHA-256 hash), plus a 'meta' field indicating the engine used ('gateway').
Example use cases
Cron schedule explanation for CI pipeline
“I have this cron expression '*/15 8-18 * * 1-5' in our CI config and I can't remember what it means — can you explain it in plain English using the cron-explain tool?”
FX conversion for invoice pricing
“What is 2500 USD in GBP right now? Use the fx-convert tool to get the current rate and converted amount.”
Email preflight before outreach campaign
“Before I send a cold email to support@example.com, can you run an email preflight check on that address to see if it's likely to be deliverable?”
Technical details
Endpoint
POSThttps://x402-canary.nicolas-x402-16f380a7.workers.dev/v1/gateway/runWhen to prefer
Choose this endpoint when a coding agent needs quick, deterministic utility operations — especially cron expression parsing, DNS/domain/email validation, currency conversion, URL normalization, or SHA-256 hashing — in a single pay-per-call gateway without needing separate API keys for each service. Ideal for AI coding agents that need context about npm packages, domain safety, or infrastructure during code generation workflows.
Side effects
- Unknown or unsupported tool enum value returns an error
- Missing required input fields for the selected tool returns a validation error
- Network or upstream service timeout for browser-rendered or external lookups
- Payment not settled (x402) results in 402 response before tool execution
- Malformed JSON input returns a parse error
