Crypto investor API: 474 rounds for 3 funds in 3 calls

By NAUT Research · · 8 min read

474 Crypto investor API backed rounds across 3 funds, returned by 3 calls, read on 31 October 2026. Logos: Coinbase Ventures, Polychain Capital, Alliance DAO, AU21 Capital, LD Capital, Shima Capital, Uniswap, Jeeves, Suilend.

NAUT tracks 474 backed funding rounds across these 3 crypto funds, and 1 call to its crypto investor API returns a fund's whole list: Alliance DAO 202 rounds, Coinbase Ventures 185, Polychain Capital 87, read on 31 October 2026. Every portfolio row carries the company, the round type, the amount in US dollars, the announce date and a lead flag, and the call costs 5 credits.

Data note. The crypto investor data here reads straight from NAUT's database on 31 October 2026, the same records the /v1 endpoints serve. Each fund also stores a portfolio count field, and that field reads 201, 180 and 83 against portfolio rows of 202, 185 and 87, so every count here is the rows themselves. Coinbase Ventures carries 0 rows flagged as lead, which is NAUT's record of stated leads for that fund and says nothing about rounds where no source named a lead. The 3 example rounds below were each checked against a published source, linked at the end.

Is there a crypto investor API for VC portfolios?

Yes, and a crypto VC API call for 1 fund is a single GET request. GET https://api.naut.so/v1/investors/polychain-capital returns the fund, its team and its portfolio, and each portfolio row holds the company, the round type, the amount in US dollars, the announce date and a lead flag. The slug in the path is the same slug as the fund's page on naut.so, so Polychain Capital at /investors/polychain-capital reads as polychain-capital in the call.

There are no query parameters on this call. Polychain Capital's 87 rows cover 70 separate companies, so a fund that backs a company twice shows up as 2 rows with their own amounts and dates. Polychain Capital's 87 rows cover 70 separate companies, so a fund that backs a company twice shows up as 2 rows with their own amounts and dates.

What does the crypto investor API return for each fund?

3 funds, 3 calls, 474 rows. A fund portfolio API response holds 1 row per backed round, and the table ranks the 3 funds by the number of rows their call returns. NAUT files Alliance DAO as Incubation, Coinbase Ventures as Exchange and Polychain Capital as Venture.

Fund Rows Lead rows With amount
202 138 201
185 0 177
87 5 85

The lead flags tell you what kind of fund you are looking at. All 138 of Alliance DAO's lead flags sit on its 138 accelerator rounds, so the flag there marks a cohort it ran rather than a priced round it set terms on. Polychain Capital has 5, out of 87. Coinbase Ventures has 0 across 185 rows.

Dates are thinner than amounts. 47 of Alliance DAO's 202 rows carry an announce date, 125 of 185 for Coinbase Ventures, and 58 of 87 for Polychain Capital, so a date filter cuts a portfolio down fast. The most recent dated row per fund on 31 October 2026 was 4 October 2026 for Alliance DAO, 26 October 2026 for Coinbase Ventures and 15 October 2026 for Polychain Capital.

Which fields come back for 1 portfolio row?

5 fields per row. Here is the same row shape filled in by 1 real round from 2 of the 3 funds, and the Coinbase Ventures round reads the same way: company Jeeves, roundType Series C, amountUsd 110000000, announceDate 2026-09-29, isLead false.

Field Alliance DAO Polychain Capital
company
roundType Funding Round Series B
amountUsd 6000000 165000000
announceDate 2024-12-05 2022-10-13
isLead false true

The 3 rows match their published announcements. Uniswap's own blog post, dated 13 October 2022, says the $165M Series B was led by Polychain Capital, which is why that row reads isLead: true. Jeeves announced a $110M Series C on 29 September 2026 that CoinFund led with Coinbase Ventures among the participants, so the Coinbase Ventures row reads false. Suilend's $6M round of 5 December 2024 was led by Robot Ventures with other firms and angels joining, and Alliance DAO is 1 of those joiners, so that row reads false as well.

The field worth building on is amountUsd. It comes back as a plain number of US dollars, so a filter for rounds over $50M or a sort by cheque size is arithmetic on the response, with no parsing of "$110M" out of a string.

How do you find a fund's slug first?

GET https://api.naut.so/v1/investors?q=capital&sort=portfolio searches funds by name and orders the result by portfolio size, which is the fastest way to turn a half-remembered fund name into a slug. The search costs the same 5 credits as a portfolio call.

What does a crypto investor API call cost?

5 credits for a data call or a search call, which makes this article's work 20 credits: 1 search plus 3 fund portfolios. GET https://api.naut.so/v1/me is free, so a quota check costs nothing.

  • Essential, $49 a month, gives 3,000 credits, so 600 data calls. Pro at $99 gives 6,000 and Team at $249 gives 15,000.
  • A 7-day free trial grants credits, and a key without enough credits gets clearly marked sample data of the same shape at 0 credits, so you can build the pipeline before you pay for the rows.
  • Too few credits on a paid key returns HTTP 402 and charges nothing.
  • Rate limit is 120 requests a minute per account, 300 on Team, so 3 portfolio calls and 1 search sit far inside it.

Plans sit at naut.so/pricing and the reference is at naut.so/docs/api.

What this tells a BD team

  • A fund's portfolio is a pre-qualified account list. Polychain Capital's 87 rows name 70 companies that have already taken money from a fund you can reference by name in a first message.
  • Sort on amountUsd to match your price. Coinbase Ventures has 177 rows with an amount on them, which is enough to pick a band and work only the companies inside it.
  • Use isLead to find the warm path. 5 of Polychain Capital's rows are lead rounds, and a lead investor is the introduction most likely to land.
  • Pull the whole thing once a week. 3 calls is 15 credits, so a weekly refresh of 3 funds costs 60 credits a month out of the 3,000 on Essential.
How a BD team turns 1 fund into an account list
  1. Find the fundA search for capital puts AU21 Capital first at 168 recorded rounds.
  2. Pull the portfolio1 call on polychain-capital returns 87 rows with company, amount and date.

  5. Open the company pageEach of the 70 companies has a NAUT page that lists its team, so you get names and channels.

What this tells a founder raising

  • Check the fund's real pace before you pitch it. Alliance DAO shows 202 rounds with 138 of them accelerator cohorts, which tells you the shape of money it writes.
  • Check whether it leads. Coinbase Ventures has 0 rows flagged as lead on NAUT's record across 185 rounds, so a founder who needs somebody to set terms should read those rows before building a round around it.
  • Look for a portfolio company close to yours and ask that founder for the introduction. Each row carries the company, so the path is 1 page away.

Is there an API for crypto VC portfolios?

Yes. NAUT's GET https://api.naut.so/v1/investors/{slug} returns 1 fund with its team and its full portfolio, which on 31 October 2026 was 202 rows for Alliance DAO, 185 for Coinbase Ventures and 87 for Polychain Capital, at 5 credits a call.

How many rounds does Coinbase Ventures have on NAUT?

185 portfolio rows across 154 companies as of 31 October 2026, with an amount on 177 of them and an announce date on 125. None of the 185 is flagged as a stated lead on NAUT's record.

Where can I find these funds, their portfolio companies and the people to contact?

On NAUT. Each fund has a page, such as Coinbase Ventures, and each of the 474 rows links to the company's own page with its team on it, so a BD lead gets the firm, the round and the name in the same place. The same records come back from GET https://api.naut.so/v1/investors/{slug}, and GET https://api.naut.so/v1/projects/{slug} returns a company with its team.

What does it cost to pull 10 fund portfolios?

50 credits, at 5 credits a data call. That is under 2% of the 3,000 credits on the $49 Essential plan, which covers 600 data calls a month.
