Quickstart
Your first call, in about a minute.
No key required to start. Every example below is a live request against the production API — copy one and run it.
1. Without a key
anonymous tierNo signup, no header. You're identified by IP and limited to roughly 10 requests per day. Enough to evaluate the shape of the data and wire a prototype.
2. With a key
dev · nonprofit · commercialSend the key as a bearer token, or as x-api-key — either works. A presented key that is unknown or revoked returns 401; it never silently falls back to the anonymous tier.
Responses on /v1/* carry X-RateLimit-Limit, X-RateLimit-Remaining and X-RateLimit-Window so you can see where you stand. Keys are issued by the operator — hello@globalhelplines.org. Nonprofits: include your registry URL and registration number.
3. Or skip HTTP entirely
If you're building on an agent, add the remote MCP server instead and let the model call it as a tool.
