Rate limits
Fair use, caching and freshness.
- No key, no enforced limit today. Please keep to about one request per second, and cache responses.
- Freshness: the indexer polls every ~10 minutes, and distributions happen once per 1,050 Bitcoin blocks (about a week). Polling more often than every minute gains nothing.
- Upstream: the indexer reads Hiro's public API, which allows about 50 requests per minute per IP without a key. The indexer stays under it, so your requests never reach Hiro directly.
- Errors:
400for invalid parameters,503from/stressbefore the first distribution is indexed.
