Crypto APIs alternative for Bitcoin data and fee estimates

Crypto APIs is a broad blockchain API suite: 35+ networks, HD wallets, webhooks and fee recommendations from $49 a month. If you run several chains, it is a sensible buy.

If Bitcoin is your whole book, you need fee rates checked against what blocks paid and balances to the satoshi. We measured both sides on 18 September 2026.

Crypto APIs leads on breadth across 35+ networks with wallets, signing and webhooks in one suite, while BitcoinDatabase indexes only Bitcoin, deeply, so you can check a fee quote or a balance against the chain itself over REST and SQL.

Side by side

Crypto APIs vs BitcoinDatabase, honestly

A fair look at what each does well. Both are capable tools. Here is where they differ.

What matters	BitcoinDatabase	Crypto APIs
Chain coverage	Bitcoin only, by design	35+ networks across UTXO, EVM, XRP, Solana and others
Entry paid plan	Developer, $49 a month, 500,000 API credits, REST API included	Starter, $49 a month or $40 billed annually, 30,000,000 credits
Mid and top plans	Growth $199 a month adds SQL, Scale $799	Scale $299 ($249 annually), Pro $799 ($665 annually)
Free tier	No free plan, a one-time demo query on the site	Yes: 100,000 credits a month, one Blockchain Events subscription, no address history
Bitcoin fee recommendations	Live mempool state plus the fee and weight of every confirmed transaction	Mempool-based fast, standard and slow, returned as strings with unit BTC
Check a fee quote against what blocks paid	Yes, same index, one SQL query over any block range	You would pull block data and compute it yourself
Address history	One year on Developer; full history from the 2009 genesis block on Growth and Scale	Latest endpoints cover roughly 14 days; full history is a separate paid-only product
SQL over the chain	Yes, POST /v1/sql from Growth	Not offered; REST and WebSocket
HD wallets, signing, broadcast	Not offered	Yes, including an MIT-licensed offline signer
AML address screening	Entity labels as context for your own review	Verify Address product, included from Starter
Unauthenticated request	HTTP 401	HTTP 401 with a clear missing_api_key code, in 0.06 to 0.14s
Best suited for	Bitcoin exchanges, wallets and analysts who need to audit fees and balances	Multi-chain products that want wallets, payments and data from one vendor

Comparison reflects general, publicly understood positioning. Capabilities change, so check each product for the latest.

What Crypto APIs costs, read from its pricing page

We read the pricing page on 18 September 2026. Four plans are listed. Free gives 100,000 credits a month with a soft throughput of 100 and a hard throughput of 1,000, one Blockchain Events subscription, and no HD wallets, address history, AML or x402. Starter is $49 a month, or $40 billed annually, with 30,000,000 credits. Scale is $299, or $249 annually, with 200,000,000. Pro is $799, or $665 annually, with 600,000,000. Overage is sold by the credit, roughly $1 per 291,545 credits on Starter and $1 per 318,522 on Scale, and the page itself points out that 600,000,000 credits cost $2,004 on Starter with overage against $799 on Pro. That is an honest page, and the arithmetic holds. The thing to price before you sign is not the plan, it is how many credits each Bitcoin call you make will burn, because that number decides which plan you are really on.

Their fee endpoint, and the unit you need to confirm

The UTXO fee reference, GET /blockchain-fees/utxo/{blockchain}/{network}/mempool, says its recommendations are built from mempool data and calculated live, which is the right approach. It returns three strings, fast, standard and slow, each described as a gas price calculated from unconfirmed transactions, with a unit field of BTC and example values of 0.000025, 0.000015 and 0.000010. The reference we read does not state the size denominator, per byte, per virtual byte or per kilobyte, while the separate smart-fee endpoint is documented as a fee per kilobyte. None of that is wrong, but a number of bitcoin with no size attached cannot go straight into a fee calculation. Call it once with a test key and convert it to sat/vB before it touches a withdrawal. We also found the developer llms.txt listing a different path, /blockchain-fees/{blockchain}/{network}/mempool/fees, and every path we tried returned 401 before routing, so the key is the only way to tell which is current.

Why no single fee estimate is safe to trust blind

On 17 September 2026 at block 967,354, mempool.space quoted 1 sat/vB for the next block, Blockstream Esplora 3.119 and BlockCypher 4.003, while the median fee rate actually paid over fifteen blocks was 0.348. mempool.space was the cheapest and closest. On 18 September at block 967,554, read at 13:03 UTC with all three reporting the same tip, the order flipped: mempool.space quoted 5 for its fastest tier, BlockCypher 2.856 and Esplora 1.069, against a median of 1.02 sat/vB across the thirty blocks 967,525 to 967,554. The estimator that was lowest one day was highest the next, by nearly five times the going rate. Any fee API, Crypto APIs included, is a model of a queue. The only defense is to measure what your own transactions paid against the blocks that confirmed them, and that is a data question rather than an estimation one.

Where Crypto APIs is the better buy

If you support Ethereum, Solana or XRP alongside Bitcoin, one integration across 35+ networks beats stitching vendors together, and nothing here replaces that. The same goes for HD wallet management by xPub, server-side transaction preparation, broadcast, and the MIT-licensed offline signer that builds and signs transactions locally without sending a private key anywhere. Their free tier is also a real one, useful for a prototype, which ours is not. BitcoinDatabase is the better fit when Bitcoin is the business and the job is to audit it: realized fee rates on your own withdrawals, balances at a past block height, full address history in one call, and SQL across the indexed chain for reconciliation and research.

Good questions

Crypto APIs vs BitcoinDatabase, answered

Four plans were listed on 18 September 2026: Free at $0 with 100,000 credits a month, Starter at $49 a month or $40 billed annually with 30,000,000 credits, Scale at $299 or $249 annually with 200,000,000, and Pro at $799 or $665 annually with 600,000,000. Extra credits are billed as overage, at roughly $1 per 291,545 credits on Starter.

Yes. The Free plan includes 100,000 credits a month, a soft throughput of 100 and a hard throughput of 1,000, and one Blockchain Events subscription. HD wallets, address history, AML screening and x402 are listed as paid only. It is enough to prototype an integration, not to run production withdrawals or reconciliation.

It depends on how many chains you run. If Bitcoin is one of many, stay with a multi-chain suite. If Bitcoin is the whole business, a Bitcoin-only index gives you fee rates you can check against confirmed blocks, balances to the satoshi at any height, and full history in one call. BitcoinDatabase does that over REST from $49 a month and adds SQL from $199.

We could not measure it without a key, and we do not guess. Its reference says estimates come from live mempool data, the same method as mempool.space. On 18 September 2026 that method quoted 5 sat/vB for the next block against a 1.02 sat/vB median actually paid across thirty blocks. Measure any provider against what your own transactions confirmed at.

The documented response returns fast, standard and slow as strings with a unit field of BTC, for example 0.000025. The reference we read does not state whether that is per byte, per virtual byte or per kilobyte. Its separate smart-fee endpoint is documented as a fee per kilobyte. Confirm with a test call and convert to sat/vB before using it in production.

Yes, on a paid plan. Its own documentation says the addresses-latest endpoints cover roughly the last 14 days and points to a separate addresses-historical product for anything older, and the pricing page lists Address History as paid only. BitcoinDatabase returns one year of history on Developer and full history from the 2009 genesis block on Growth and Scale, through the same endpoint.

At entry they cost the same, $49 a month. Above that the plans are not like for like: Crypto APIs Scale is $299 for more credits across 35+ chains, while BitcoinDatabase Growth is $199 and adds SQL over the Bitcoin chain. Credits are not comparable units either: our Developer plan carries 500,000 API credits against 30,000,000 on their Starter, and the cost per call differs on each side. Price your real call volume on both before deciding.

No. BitcoinDatabase provides informational on-chain data and analytics only. It is not investment, financial or legal advice. Vendor facts on this page were read directly on 18 September 2026, and pricing, credit rules or endpoints may change after that date. Crypto APIs is a trademark of its owner.
