Changelog

Every shipped change, newest first. Additive changes are listed for completeness even when they require nothing of you.

2026-08-19#

Added#

• settlement_confidence on payment intents, allowing early announcement at inclusion rather than finality. See Chains and finality for the trade-off.
• payment_intent.reverted event, emitted when a reorg removes a payment previously announced as succeeded.
• underpayment_tolerance_percent on payment intents, defaulting to 0.
• juicepay verify CLI command for pre-flight batch CSV validation.

Changed#

• Batch validation now reports every failing leg rather than stopping at the first, up to a ceiling of 100 reported legs.
• price_impact is now always present on quote objects, including for small orders where it rounds to zero.

Fixed#

• balance.updated could be delivered with a stale as_of when two changes landed within the same second. The snapshot is now monotonic.

2026-07-30#

Added#

• tron as a supported settlement chain for USDT payouts.
• recipient.screening_updated event, fired when a screening verdict changes after the fact.
• Per-key allowed_ips restrictions on API keys.

Changed#

• payout.leg.broadcast now includes finality alongside confirmations, so consumers no longer need to infer it.
• Retry ceiling for webhook deliveries raised from 12 hours to 24 hours.

Deprecated#

• POST /v1/transfers. Use POST /v1/payouts instead. The old endpoint continues to work and will be removed no earlier than 2027-07-30.

2026-07-11#

Added#

• partial_fills on limit orders, allowing tranche execution on thin books.
• limit_order.partially_filled event.
• Settlement report exports in Parquet in addition to CSV and JSONL.

Changed#

• Quote TTLs are now dynamic per pair. Thin pairs quote for shorter windows and now say so in the response rather than expiring early without explanation.

Fixed#

• Idempotency keys containing uppercase characters were hashed case-sensitively, causing a retry with different casing to create a duplicate resource. Keys are now normalised before hashing.

2026-06-24#

Added#

• swap.settled now includes executed_rate so consumers can detect when a refreshed quote produced a different price.
• GET /v1/ledger_entries accepts source as a filter.

Changed#

• Error responses include doc_url, linking straight to the relevant section of this documentation.

2026-05-28#

Added#

• solana and arbitrum receive addresses on all sub-accounts.
• juicepay listen gained --forward-to for custom paths.

Removed#

• The legacy /v0/ namespace, after a twelve-month deprecation period.

Deprecation policy#

When we deprecate something:

1. The changelog entry names the replacement and the removal date no earlier than twelve months out.
2. Responses that use the deprecated surface include a JuicePay-Deprecation header.
3. The dashboard surfaces a warning for any key still exercising the deprecated path.

Nothing is removed without all three.
