Anvil Mesh#

Query live data feeds, verify BSV transactions, and discover paid services on the Anvil mesh network.

What Anvil Does#

Anvil is a mesh of BSV nodes that:

• Publishes signed data feeds (price oracles, sensor data, any structured data)
• Verifies BSV transactions via SPV with merkle proofs against synced headers
• Accepts micropayments via HTTP 402 — non-custodial, sub-cent, instant settlement on BSV

Discovery#

Find a node's capabilities:

bash

curl https://<node>/.well-known/anvil

Returns a machine-readable manifest listing all available data topics, payment options, and mesh info.

Find payment details:

bash

curl https://<node>/.well-known/x402

Returns endpoint pricing and payment models (HTTP 402 standard).

Query Data#

Browse available topics:

bash

curl https://<node>/stats

The envelopes.topics field lists all active data topics with envelope counts.

Fetch envelopes for a topic:

bash

curl "https://<node>/data?topic=oracle:rates:bsv&limit=5"

Returns signed envelopes with payload, publisher pubkey, signature, TTL, and timestamp.

Verify a Transaction#

bash

curl "https://<node>/tx/<txid>/beef"

Returns the transaction in BEEF format with merkle proof for SPV verification.

Payment Flow (HTTP 402)#

If an endpoint requires payment:

1. Request the endpoint
2. Receive HTTP 402 with price and payment address
3. Create a BSV transaction for the exact amount
4. Resend request with payment proof in X402-Proof header
5. Receive data — transaction settles on BSV network

No accounts, no API keys, no signups. Sub-cent costs, instant settlement.

Example: Get BSV/USD Price#

bash

curl -s "http://212.56.43.191:9333/data?topic=oracle:rates:bsv&limit=1" | jq '.envelopes[0].payload | fromjson | .USD'
