This page maps your existing v2 integration onto v3. Start with the recipes if you think in terms of screens and workflows — each shows a typical v2 call and the v3 calls that replace it.
Use the full endpoint reference at the bottom as the complete lookup table. End with the checklist before you cut over.
There is no full-metadata endpoint in v3. Where v2 returned an entire entity in one call, v3 splits the data across focused endpoints.
Migration recipes
Each recipe shows one v2 call and the set of v3 calls that replace it. Request only the slices your screen needs — every call draws credits independently. Minimum plan reflects the highest-gated endpoint in the recipe.
1. Full coin card
Minimum plan: Advanced.
2. Tokenomics & unlocks
vesting/chart now returns the delta unlocked per period, not a running
cumulative total. A from/to window returns deltas inside the window only,
without a baseline.
3. Fund data
Minimum plan: Business.
4. Funding rounds
The list feed gives the overview; the detail endpoint adds lead-investor breakdown. Minimum plan: Business.
5. Drophunting
Minimum plan: Business.
Full endpoint reference
Complete v2 → v3 lookup by group. For renamed 1:1 endpoints, the v3 path is given directly; follow the reference page for renamed fields.

Two cross-cutting rules that can break clients silently:
convert applies to fiat conversion only. It does not convert between cryptocurrencies.- ATH / ATL / high24h / low24h are always returned in USD and are never affected by
convert.
