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:

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

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

Find payment details:

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

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

Query Data

Browse available topics:

curl https://<node>/stats

The 

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

Fetch envelopes for a topic:

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

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

Verify a Transaction

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

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

Live Nodes

  • http://212.56.43.191:9333
    — anvil-prime
  • http://212.56.43.191:9334
    — anvil-one

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

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