What is AXL?

AI agents can't talk to each other. They communicate in English prose (50-100 tokens), JSON (even worse), or proprietary formats requiring per-framework SDKs. In a 100-agent network, this produces 22.5 million tokens of negotiation overhead before any productive work happens.

AXL eliminates this. One URL (@axlprotocol.org/rosetta) teaches any agent the complete language on first contact. The protocol has been validated across 11 agents from 10 computational paradigms with 100% parse validity and 95.8% LLM comprehension across four major architectures.

Install

pip install axl-core

Quick Start

Parse a packet:

from axl import parse

packet = parse("π:5:0xSIG:0.001|S:OPS.4|@api.example.com|ERR500|latency|4500ms|500ms|ALERT|URG|LOG")
print(packet.domain)         # "OPS"
print(packet.body.fields)    # ['@api.example.com', 'ERR500', 'latency', '4500ms', '500ms', 'ALERT']
print(packet.flags)          # ['URG', 'LOG']

Emit a packet:

from axl import emit, Packet, Preamble, Body, PaymentProof

packet = Packet(
    preamble=Preamble(payment=PaymentProof(agent_id="5", signature="0xSIG", gas=0.001)),
    body=Body(domain="OPS", tier=4, fields=["@api.example.com", "ERR500", "latency", "4500ms", "500ms", "ALERT"]),
    flags=["URG", "LOG"]
)
print(emit(packet))
# π:5:0xSIG:0.001|S:OPS.4|@api.example.com|ERR500|latency|4500ms|500ms|ALERT|URG|LOG

CLI:

axl parse "π:5:0xSIG:0.001|S:SIG.3|BTC|69200|↓|RSI|.64|SIG"
axl validate "π:5:0xSIG:0.001|S:SIG.3|BTC|69200|↓|RSI|.64|SIG"
axl translate --to english "π:5:0xSIG:0.001|S:SIG.3|BTC|69200|↓|RSI|.64|SIG"

Domains

The Stack

AXL is the missing language layer in the agent internet:

Proven

Two live experiments. Real agents. Real packets. Real results.

Architecture

• Parser: parse(string) -> Packet dataclass
• Emitter: emit(Packet) -> AXL string (round-trip proven)
• Validator: Schema check, type check, tier range
• Translator: AXL <-> English <-> JSON
• CLI: axl parse, axl emit, axl validate, axl translate
• Zero runtime dependencies

v3 Support

Full v3 parser, emitter, validator, and translator included. Auto-detects v1 vs v3 format. All v1 code preserved for backward compatibility.

from axl import parse_v3, emit_v3, validate_v3, v3_to_json, v3_to_english

pkt = parse_v3("ID:MKT-01|OBS.99|$BTC|^67420|^fund:-0.02%+^OI:12.4B|NOW")
print(pkt.operation)      # Operation.OBS
print(pkt.confidence)     # 99
print(pkt.subject_value)  # BTC

print(emit_v3(pkt))       # ID:MKT-01|OBS.99|$BTC|^67420|^fund:-0.02%+^OI:12.4B|NOW
print(v3_to_english(pkt)) # MKT-01 observes $BTC at ^67420 with 99% confidence.
print(v3_to_json(pkt))    # {"v":"3","id":"MKT-01","op":"OBS","cc":99,...}
print(validate_v3(pkt))   # [] (no errors)
